Dev Notes March 15 2026

● In the Terminal app on your Pixel, run this single command:

mkdir -p ~/.ssh && echo “ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJA8U0MlXt/YsF15XAsOerwGre4JA6wEYrhqz33ji6QR scythe-avf” >> ~/.ssh/authorized_keys && chmod 700 ~/.ssh && chmod 600
~/.ssh/authorized_keys && echo “Key added. IP: $(hostname -I)”

Once you confirm it ran, I’ll SSH straight in and start installing Python + DuckDB + PyArrow inside the VM.

● Environment loaded: 1 MCP server, Visual Studio Code connected

❯ droid@debian:~$ sudo mkdir -p ~/.ssh && echo “ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJA8U0MlXt/YsF15XAsOerwGre4JA6wEYrhqz33ji6QR scythe-avf” >> ~/.ssh/authorized_keys && chmod 700
~/.ssh && chmod 600
~/.ssh/authorized_keys && echo “Key added. IP: $(hostname -I)”
chmod: missing operand after ‘600’
Try ‘chmod –help’ for more information.
-bash: /home/droid/.ssh/authorized_keys: Permission denied

◐ The issue is a line-wrap in the terminal that broke the chmod command. The ~/.ssh directory might already exist with wrong permissions, or the authorized_keys file has a permission
issue. Let me give a clean corrected command.

● Line-wrap broke the command. Run this clean version (single line, no wrapping):

● Print corrected command to paste
$ echo ‘sudo install -d -m 700 ~/.ssh && echo “ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJA8U0MlXt/YsF15XAsOerwGre4JA6wEYrhqz33ji6QR scythe-avf” | sudo tee -a ~/.ssh/authorized_keys && sudo
chmod 600 ~/.ssh/authorized_keys && sudo chown -R droid:droid ~/.ssh && echo “Done. IP: $(hostname -I)”‘
└ 2 lines…

● Paste exactly this into the Terminal (it’s one line):

sudo install -d -m 700 ~/.ssh && echo “ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJA8U0MlXt/YsF15XAsOerwGre4JA6wEYrhqz33ji6QR scythe-avf” | sudo tee -a ~/.ssh/authorized_keys && sudo
chmod 600 ~/.ssh/authorized_keys && sudo chown -R droid:droid ~/.ssh && echo “Done. IP: $(hostname -I)”

You should see Done. followed by the VM’s IP (likely 10.107.190.x). Share that output and I’ll connect immediately.

❯ droid@debian:~$ sudo install -d -m 700 ~/.ssh && echo “ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJA8U0MlXt/YsF15XAsOerwGre4JA6wEYrhqz33ji6QR scythe-avf” | sudo tee -a

◐ The key was added (tee printed the key), but chown failed because the group is different. The key is in authorized_keys though. Let me just fix the ownership and try SSH. The user is
“droid” but the group might be something else.

● Key is written — tee printed it successfully. The chown failed on group name, but that’s fine. Just fix ownership:

The VM server needs to survive reboots — want me to add a systemd service inside the VM for that, or move on to wiring the hypergraph + space-time cube analytics into the query
layer?

◐ RFNode has frequencyHz and RSSI but no bearing. ScytheEntity has no freq/bearing fields at all (they live in metadata).

Here’s my plan:

ScytheEntity.java: Add freqMhz and bearing fields, extract from metadata.freq/metadata.bearing in fromJson()
EventStreamer.java: Add recordRfDetection() convenience method that builds a proper rf.detection payload
ScytheDropDownReceiver.java: In onEntity() for RF entities, call EventStreamer.recordRfDetection(); also add entity.move streaming for non-RF position updates
The SSE stream from the RFScythe server on port 8080 sends entity events that the ATAK plugin consumes, and I need to forward RF entities to the VM analytics pipeline as rf.detection events. Now I’m realizing ScytheEntity doesn’t currently extract the metadata field containing frequency and bearing data, so I’m losing that information. I should parse those values and then add a method to EventStreamer that records RF detections with all the
relevant sensor parameters, then wire it up in the receiver to capture these events when they come through.

● Now I have the full picture. Three files to edit:

ScytheEntity — parse metadata.freq + metadata.bearing
EventStreamer — add recordRfDetection() convenience method + recordEntityMove()
ScytheDropDownReceiver — wire both in onEntity() + add CoT map listener for live ATAK entity positions

◐ Several issues:

java.util.List and java.util.ArrayList – the imports moved around; I need to add them back
MapItem.OnGroupChangedListener – this interface probably doesn’t have the methods I expected; need to check what methods MapGroup listeners use in ATAK
MapGroup.removeOnGroupChangedListener – might not exist (might be removeOnGroupChangedListener vs a different API)
MapGroup.forEachItem – might not exist in ATAK SDK
Several other cannot find symbol errors Let me check the ATAK SDK API for MapGroup.

● Check ATAK SDK MapGroup/MapItem APIs

└ 7 lines…

◐ The ATAK SDK has these group listeners:

MapGroup$OnGroupListChangedListener — for group add/remove
MapGroup$OnItemListChangedListener — for item add/remove
MapGroup$MapItemsCallback — callback for item iteration
MapGroup$OnItemCallback — callback And PointMapItem‘s listener:
PointMapItem$OnPointChangedListener — for position changes I need to use these correctly. Let me check what the actual interfaces look like.Also, I notice there’s no MapItem.OnGroupChangedListener – the listener I used in the implements clause doesn’t exist. I need to use the correct ATAK interfaces.Let me rethink the
approach. The map item tracking is an optional enhancement – the core RF detection pipeline is the SSE stream path. I’m going to simplify this by dropping the map group listener approach entirely since the API surface is uncertain. The core flow stays the same: SSE stream feeds RF entities into recordRfDetection(), and non-RF entities go through recordEntityMove(). This
keeps things straightforward and focused on what actually matters.

● Check MapGroup and PointMapItem API signatures
$ jar tf /home/spectrcyde/NerfEngine/ATAKScythePlugin/app/libs/atak-civ-4.6.0-api.jar | grep -E “PointMapItem|OnPoint” | head -20

└ 18 lines…

◐ Now I know the correct interfaces. I need to fix:

Implement MapGroup.OnItemListChangedListener (not MapItem.OnGroupChangedListener)
The methods are onItemAdded(MapItem, MapGroup) and onItemRemoved(MapItem, MapGroup) ✓ (same signatures I used)
OnGroupListChangedListener only has onGroupAdded and onGroupRemoved – so I should also implement that
For position changes: PointMapItem.OnPointChangedListener with onPointChanged(PointMapItem) – the lambda parameter is PointMapItem, not item (need to check return type)5. forEachItem takes MapGroup.MapItemsCallback which returns boolean (false to continue), and I need to use removeOnGroupListChangedListener and removeOnItemListChangedListener instead of the non-existent removeOnGroupChangedListener. I also need to
restore the List and ArrayList imports. I’ll create the listeners as separate anonymous inner class instances to keep the code clean and avoid cluttering the class interface.

● Now I know the exact interface names. Let me fix the implementation properly:

Changes (BUILD SUCCESSFUL, APK installed ✅)

ScytheEntity.java

Added freqMhz, bearing, emitterId fields
fromJson() now reads them from metadata.freq / metadata.bearing / metadata.emitter_id EventStreamer.java — 3 new convenience methods:
recordRfDetection(sensorId, lat, lon, alt, freqMhz, bearing, emitterId) — emits rf.detection with sensor/freq/bearing/emitter_id payload; the hypergraph groups detections by frequency to build TRIANGULATED_FROM edges
recordEntityMove(entityId, lat, lon, alt) — emits entity.move
recordSwarmUpdate(swarmId, memberIds, lat, lon) — emits swarm.update with members_list ScytheDropDownReceiver.java — two new data sources:

SSE stream (onEntity()): RF entities now call recordRfDetection() with freq/bearing from metadata; non-RF entities call recordEntityMove()
CoT map listener (MapGroup.OnItemListChangedListener + OnGroupListChangedListener): registers on the ATAK root map group at construction; emits entity.spawn on first sight, entity.move on every CoT position update, entity.remove on deletion — covers all
friendly/hostile/unknown tracks regardless of SSE

◐ The crash is confirmed: FORTIFY: pthread_mutex_lock called on a destroyed mutex in com.atakmap.app.civ. This is the exact same NDK bionic FORTIFY issue we identified earlier. This is happening at the GLThread during ATAK startup on Android 16.

The roadmap file appears to contain a copy of a chat session about the SQLite shim approach. Let me read it more carefully to get the actual sections with phases/milestones.

The crash root cause is known:

ATAK 4.6.0 crashes on Android 16 (SDK 36)
Root cause: FORTIFY pthread_mutex_lock on destroyed mutex in libatakjni.so / libcommoncommo.so
Also libsqlite3.so removed from Android 16 The roadmap seems to be discussing the libsqlite3 shim approach as the fix—building a bundled libsqlite3.so shim to include with the plugin or ATAK itself. But the roadmap content I’m reading looks like it’s the same chat transcript I was already shown earlier
in this conversation. Let me check the actual roadmap file content more carefully. The cat output shows “Yep—this is a classic trick…” which matches what I saw before, and head -5 confirms it’s the same material. So Ben created this roadmap file by pasting that chat discussion
about the SQLite shim approach—the roadmap is essentially documenting the strategy to build and bundle a libsqlite3.so shim with ATAK to resolve the Android 16 crash. Now I need to read through the full roadmap to see what phases or milestones are actually defined.

◐ The roadmap’s primary immediate action is:

SQLite shim — allow ATAK to start on Android 16
Verify plugin loading The roadmap also covers a lot of the architecture that’s already been built (DuckDB, hypergraph, etc.). The key issue to fix now is the ATAK crash on Android 16. The approach from the roadmap is to build a libsqlite3.so shim that:
Exports the SQLite symbols ATAK expects
Forwards calls to a bundled SQLite implementation (or stubs them safely)
Gets packaged with the ATAK APK… but wait — we can’t modify the ATAK APK directly (it’s the official release from TAK.gov). But looking deeper, the actual crash isn’t just a missing SQLite library—it’s a FORTIFY: pthread_mutex_lock called on a destroyed mutex error in libatakjni.so/commoncommo.so on the GLThread, which points to a bionic hardening issue with NDK compatibility
rather than a simple symbol resolution problem. The real issue is that Android 16’s FORTIFY allocator is catching ATAK’s native code trying to lock a mutex that’s already been destroyed, which means this is a genuine bug in ATAK that was masked on older Android versions. I could try building a SQLite shim, but
that won’t address the underlying pthread issue. My better options are finding an older ATAK CIV version that runs on Android 13-14, patching the APK directly by extracting and modifying the native libraries, or building from the source code that’s already
available in the assets folder. Looking at the crash details more closely, the mutex at that specific memory address is being locked after destruction during GLThread startup—likely in the map rendering initialization code within libatakjni.so. The fact that the same address appears
consistently across crashes suggests this is a global or static mutex that’s either being destroyed prematurely or initialized incorrectly. Building the SQLite shim as a first step might help narrow down whether that’s the culprit. The crash is happening in the
GLThread during map rendering, which could point to the 16KB alignment issue mentioned earlier rather than just the SQLite library. I need to examine the full backtrace to identify which library is actually failing, and determine whether ATAK bundles its own
libsqlite3.so or if that’s a separate dependency. Given the roadmap priority is fixing the crash on Android 16, I should focus on the pthread_mutex FORTIFY issue as the primary blocker. approach from roadmap: build libsqlite3.so shim But the pthread_mutex crash may be deeper. Let me check if ATAK already bundles a libsqlite3.so or not, and get the full crash backtrace. The key actions:
Pull the ATAK APK from device
Inspect its native libs
Determine if the crash is libsqlite3-related or pthread-related
Build the appropriate shim or apply the appropriate fix Let me also look at section “# Architecture: HTTP vsock Upgrade” and other roadmap sections to understand what else is planned beyond the crash fix. Looking at the broader roadmap sections:

vsock upgrade (HTTP → vsock for events, bypassing network stack)
ATAK overlay pipeline (rendering hypergraph edges as ATAK map primitives) These are future phases though. Right now I need to focus on resolving the ATAK crash, so I’m going to extract the APK from the device and examine what native libraries it contains.

● The roadmap’s immediate priority is #1: SQLite shim to let ATAK start on Android 16. Let me properly diagnose the crash before building the shim:

└ 45 lines…

◐ Now I have a clearer picture:

libsqlite3.so is NOT a dependency of any ATAK lib — libsqlite3 was always in the system but ATAK apparently doesn’t directly depend on it in the APK’s native libs. ATAK might load it dynamically via dlopen() but doesn’t have a static NEEDED entry for it.
libstdc++.so is depended on by multiple ATAK libs — This is NOT a public NDK API lib on Android 16. libstdc++.so was removed from Android 7.0+. ATAK bundles its own libgnustl_shared.so to provide the GNU STL, which was the standard in older NDK versions but has been deprecated since NDK r18 and removed entirely by r21. The APK was likely built with an old NDK toolchain that relied on gnustl instead
of the modern libc++, so the STL dependency is technically satisfied by the bundled library, though this creates compatibility issues with the pthread_mutex functions. The problem is that libgnustl_shared.so uses weak symbols for pthread_mutex_lock, which means these functions defer to the system’s libc implementation. On Android 16, the strengthened FORTIFY checks catch the misuse pattern, resulting in the crash: FORTIFY: pthread_mutex_lock called on a destroyed mutex. This happens because the way libgnustl_shared.so manages pthread_mutex_t objects violates Android 16’s stricter safety requirements. I’m also checking whether libpgscmedia.so and other ATAK libraries depend on libstdc++.so, which is a system library that may no longer be available on Android 16, and tracing through the full dependency chain to see where the actual incompatibility lies. so
the shim approach won’t solve it. On modern Android, libstdc++.so is essentially a stub redirecting to libc++, but the real issue is that libpgscmedia.so is linked against both libgnustl_shared.so and libstdc++.so, creating a mismatch where the old GNU
runtime’s std::mutex objects are being validated by bionic’s stricter FORTIFY checks on Android 16. The crash is actually a use-after-free on a mutex — a C++ static initialization order problem where a mutex gets destroyed but then accessed later, likely from a different thread like the GL renderer. This is a fundamental issue in the ATAK native code itself
that can’t be fixed through library shimming. The real solution would be rebuilding ATAK with a newer NDK using libc++ instead of the old GNU STL. But there are some workarounds worth trying: finding a newer ATAK version (4.10+ reportedly works on Android 14+), testing on an emulator with an older API level to avoid the FORTIFY checks, or attempting an LD_PRELOAD trick with a custom library that
intercepts mutex operations to skip destroyed ones. The most practical path forward seems to be building a shim library that patches pthread operations and injecting it through the plugin’s native libraries, though I’m realizing the constraints here—the plugin loads in ATAK’s process but can’t necessarily
intercept system calls from other libraries without getting into complex PLT patching territory. Maybe the real solution is building a libsqlite3.so shim instead, which could handle both the mutex issue and the library compatibility problem at once. actual path
to making ATAK work is:
Use adb shell setprop wrap.com.atakmap.app.civ 'LD_PRELOAD=/data/local/tmp/libfixmutex.so'
Build the fixmutex lib that intercepts pthread_mutex_lock and handles destroyed mutexes gracefully This is the most practical approach on a rooted/unlocked device. The wrap. property causes Android to load the app with a wrapper that sets LD_PRELOAD. Since the device has an unlocked bootloader and we have sudo access in the Debian VM, I likely have root via adb root, so I can set the wrap property and build a mutex fix library to intercept the destroyed mutex calls. The real issue is that mutex at
0x7c383fc288 is being accessed after destruction, which triggers FORTIFY’s abort — I need to trace exactly where this is happening to understand if it’s a lifecycle issue or a threading bug. For the ATAK crash, the most practical approach is building ATAK CIV
from source in assets/AndroidTacticalAssaultKit-CIV-main/ — either by upgrading to a version using libc++ instead of gnustl, or patching the mutex issue directly. The crash itself is an Android 16 FORTIFY check that catches destroyed mutexes, which would’ve
silently failed or caused undefined behavior on older Android versions, so I’m wondering if there’s a way to disable that specific FORTIFY check. I’m exploring whether Android’s wrap.sh mechanism or libc properties could help, but those mainly control malloc debugging or error output rather than disabling the FORTIFY abort itself. The real issue is that Android 16 introduced this specific check for
pthread_mutex_lock on destroyed mutexes, whereas Android 14/15 might’ve only warned about it. Looking at this differently, the roadmap items that actually matter are the SQLite shim, vsock upgrade, and ATAK overlay rendering—but the crash itself stems from the mutex check, not SQLite. The most direct solution would be to create an interposer library that
intercepts the problematic mutex calls before they hit the FORTIFY check. That said, there’s a simpler path: checking whether ATAK can run in a compatibility mode on this Pixel, since Android 16 has SDK-level compatibility behaviors, though FORTIFY operates at the libc level so that might not help. Let me look more carefully at where
the crash is actually happening in the GLThread to understand if there’s something else going on. The most practical next steps are trying to disable certain restrictions with adb, checking if root access is available, and verifying whether a newer ATAK version might resolve this. But I need to examine the full tombstone to pinpoint exactly where the
pthread_mutex crash originates, since the roadmap mentions building a sqlite shim but the actual failure is FORTIFY-related.

◐ Now I have the real crash diagnosis! It’s NOT a pthread_mutex_lock FORTIFY issue. The abort message is:

  Abort message: 'terminating due to uncaught exception of type std::invalid_argument: normal must be normalized.'

The crash is in CesiumGeometry::Plane::Plane(glm::vec<3, double>& normal, double) — it validates that the plane’s normal vector is normalized (length ≈ 1.0), and it throws std::invalid_argument when it’s not.

The crash stack:

CesiumGeometry::Plane::Plane(normal, distance) throws std::invalid_argument: normal must be normalized
CesiumGeometry::createCullingVolume(viewMatrix) calls Plane constructor
Cesium3DTilesSelection::ViewState::ViewState(...) calls createCullingVolume
CesiumBridge_render(...) — main render entry point
GLThread via android.opengl.GLSurfaceView$GLThread.guardedRun This is a completely different issue from what we thought! It’s a floating-point normalization bug in the Cesium 3D Tiles renderer inside libtakengine.so. The view matrix being passed to the culling volume creation is producing an unnormalized normal vector,
which the Plane constructor rejects. The real problem is that GLSurfaceView hasn’t finished initializing its viewport on the first render cycle, so the camera matrix contains degenerate values that fail the normalization check. The Cesium library throws an uncaught exception that crashes the
GLThread before ATAK can fully load, not a SQLite issue at all. The issue is that CesiumBridge_render is a JNI function invoked from Java’s GLSurfaceView.Renderer.onDrawFrame(), and when the C++ exception propagates through the JNI boundary without being
caught, newer Android versions abort the process rather than letting it pass through. The stack trace shows the exception originates in Cesium’s plane construction when given an invalid normal vector, likely due to zero viewport dimensions on Android 16, and
libtakengine’s exception handler is terminating the app instead of allowing graceful recovery. The root cause is that on initial render, the view matrix has a degenerate forward vector causing Cesium to compute a zero normal that fails normalization. This is
likely triggered on Android 16 due to changes in how GLSurfaceView initializes. I’m considering three potential fixes: patching the native library directly with a try-catch, rebuilding ATAK with a fixed Cesium version, or wrapping the native call in Java
exception handling — though the last option is complicated since CesiumBridge_render is native code. Other approaches include using LD_PRELOAD to skip early frames until the viewport stabilizes, disabling 3D Tiles rendering if ATAK supports it, or checking for debug system properties. This actually sounds like a known issue in the TAK community on Android
14/15/16, and the problem stems from the Cesium Plane constructor’s validation check that was added in newer versions — when the normal vector is zero, it fails. The most practical solution would be intercepting the JNI call to CesiumBridge_render through our own native library loaded first, or using PLT/GOT patching on the Plane constructor itself. But PLT patching only works across library boundaries, not within
libtakengine.so. The real issue is that the C++ exception from native code propagates through JNI without being caught by ATAK’s rendering error handlers, so I need to figure out where the exception is escaping and either catch it at the JNI boundary or prevent
it from being thrown in the first place. I’m considering using the wrap.sh mechanism on this debug device to intercept the process startup and potentially wrap the rendering calls with error handling. However, LD_PRELOAD won’t directly hook the C++ constructor since it’s an internal symbol within libtakengine.so rather than an imported one. I could try hooking lower-level functions like pthread_create or glDrawArrays, but that approach gets complicated
quickly. Building ATAK from source might be more straightforward. The source code is available in the assets folder, and the Cesium integration there could have a patched version. It’s a massive undertaking, but it’s the proper solution. Alternatively, ATAK might expose system properties or preference files to disable 3D tiles
rendering, so I should check if there’s a way to toggle Cesium off before startup. Another angle is intercepting at the Java level through the ATAKMapView renderer, since the crash happens in onDrawFrame(). the Java level. But we don’t have the ATAK source to
modify… wait, actually we DO have the source in assets/AndroidTacticalAssaultKit-CIV-main/. Looking at the ATAK source, the 3D tiles rendering is in atak/ATAK/app/src/main/java/ somewhere, calling CesiumBridge_render. We could build ATAK from source with this patched. Option E: Set ATAK preference to disable Cesium 3D Tiles before first run
ATAK stores preferences in:

  /sdcard/atak/profiles/default/

or in shared preferences. If we can inject a preference file that disables 3D tiles before ATAK launches…

Actually, let me check the ATAK source for any relevant settings.

Option F: Check for fixes in newer ATAK versions
ATAK 4.10 or 5.x might have already addressed this Cesium bug, but we’re limited to what’s available on TAK.gov. The most practical approaches right now are finding a preference to disable 3D terrain tiles, checking the source code for that setting, or attempting
a binary patch on libtakengine.so to remove the problematic exception throw from the geometry code. ARM64 instruction that triggers the throw and replacing it with a NOP. This is actually doable since we have the binary.

Let me find the throw in the binary and calculate its offset. From the tombstone:

Frame #06: CesiumGeometry::Plane::Plane(glm::vec<3, double>, double)+188 at offset 0x0000000000bfe2bc in libtakengine.so
Frame #05: __cxa_throw+128 at offset 0x00000000012bf658 The CesiumGeometry::Plane::Plane at offset +188 in the function throws. We need to:

Extract the ARM64 instruction at libtakengine.so + 0x0000000000bfe2bc
Replace the throw with a ret or a b to after the throw path
This would make Plane() silently accept unnormalized normals instead of throwing Actually, for the Plane with an unnormalized normal — if we just skip the throw and proceed, the Plane will be initialized with the unnormalized (potentially zero) normal. The culling computation might be wrong but at least ATAK won’t crash. For 3D tiles rendering on initial frame when the normal is zero, the rendering would be wrong for those specific frames but it won’t crash. Eventually when the camera is properly set up, the normals will be normalized. This binary patch approach is feasible and
targeted — I have the exact offset from the tombstone where the throw occurs, so I can verify the bytes at that location and replace them with a NOP or return instruction. Let me try a different approach though: checking if ATAK has a preferences file that can disable 3D tiles or Cesium rendering before it even attempts to render. ATAK stores preferences in /data/data/com.atakmap.app.civ/shared_prefs/, and there might be settings
like cesium3DTilesEnabled or terrain3D that we can disable to avoid triggering this code path entirely.

● Excellent — the real crash is completely different from what we expected. It’s not a pthread_mutex or libsqlite3 issue. The abort is:

std::invalid_argument: normal must be normalized.

in CesiumGeometry::Plane::Plane() called from CesiumBridge_render() in the GL thread. ATAK 4.6.0’s Cesium 3D Tiles renderer throws an uncaught C++ exception when the camera view matrix is degenerate on first render.

◐ Found it! The preference key is atakGlobeModeEnabled. If we set this to false in the ATAK shared preferences, ATAK won’t use the Cesium 3D globe mode, which means CesiumBridge_render won’t be called on first render, and ATAK won’t crash.

◐ The /sdcard/atak/config/prefs/ directory exists but is empty. ATAK loads preferences from this directory on startup – this is ATAK’s “startup configuration” path where it loads .pref files.

ATAK reads .pref files from /sdcard/atak/config/prefs/ on first load
These .pref files are XML format with <preference> entries
They override defaults for SharedPreferences So if we create a file /sdcard/atak/config/prefs/globe_disable.pref with the content to disable globe mode, ATAK should pick it up on next startup. I need to figure out the exact XML structure these preference files should use.

Inside that, <entry key="atakGlobeModeEnabled" class="class java.lang.Boolean">false</entry> Let me construct this .pref file and push it to /sdcard/atak/config/prefs/. The file format based on the export code (line 193-197):

  <?xml version='1.0' encoding='UTF-8' standalone='yes' ?>


  <preferences>
    <preference name="com.atakmap.app_preferences">
      <entry key="atakGlobeModeEnabled" class="class java.lang.Boolean">false</entry>
    </preference>
  </preferences>

Looking at the PreferenceControl.loadSettings method, the name attribute on the <preference> element gets mapped to DEFAULT_PREFERENCES_NAME for com.atakmap.app_preferences. I need to check what that constant actually resolves to and verify the exact
attribute name expected.

So the preference names like com.atakmap.app_preferences or com.atakmap.civ_preferences all map to the same default preferences name. The export format uses <entry key="..." class="...">value</entry> elements nested inside preference tags, but I’m seeing
references to both <preference key and <entry key patterns in the import logic, so I need to trace through the actual export format more carefully to understand which one is correct. I need to trace through the loadSettings method to understand the exact
structure of the preference element and how the name attribute is being used.

● Find exact .pref file element structure for ATAK preferences
$ # Find the saveSettings export format — how does it write elements
grep -n “preferences|name|saveSettings” \ /home/spectrcyde/NerfEngine/assets/AndroidTacticalAssaultKit-CIV-main/atak/ATAK/app/src/main/java/com/atakmap/app/preferences/PreferenceControl.java \ 2>/dev/null | grep -E “append|name.pref|pref.*name|preferences>” | head -20…
└ 28 lines…

◐ Now I have the format. The .pref file looks like:

  <preferences>
    <preference version="1" name="com.atakmap.app_preferences">
      <entry key="atakGlobeModeEnabled" class="class java.lang.Boolean">false</entry>
    </preference>
  </preferences>

Now I need to push this file to /sdcard/atak/config/prefs/ and then restart ATAK.

The key question: does ATAK read .pref files from config/prefs/ on startup automatically, or does it need to be imported manually?

Looking at the ATAK source, I can see that PreferenceControl loads settings from config files in a loop, and there’s a FileChecker watching the DIRPATH directory. The ImportPrefSort class handles auto-importing .pref files that are placed in the watched
directory, so ATAK should automatically detect and import the file when it’s dropped into config/prefs/.

Now I need to figure out what FileSystemUtils.getItem(DIRNAME) actually resolves to.

● Find ATAK PreferenceControl directory path constant
$ grep -n “DIRNAME|getItem|config” \
/home/spectrcyde/NerfEngine/assets/AndroidTacticalAssaultKit-CIV-main/atak/ATAK/app/src/main/java/com/atakmap/app/preferences/PreferenceControl.java \

2>/dev/null | head -5

echo “”…
└ 6 lines…

◐ The DIRPATH is /sdcard/atak/config/. So ATAK reads preference files from /sdcard/atak/config/.

But looking at DIRNAME in PreferenceControl:

  public static final String DIRNAME = FileSystemUtils.CONFIG_DIRECTORY + File.separator + "prefs";

Wait let me check the full line 59.

● Read NerfEngine/assets/AndroidTacticalAssaultKit-CIV-main/atak/ATAK/app/src/main/java/com/atakmap/app/preferences/PreferenceControl.java lines 55-75
└ 21 lines read

◐ So DIRNAME = "config/prefs" → DIRPATH = /sdcard/atak/config/prefs/.

That’s exactly the directory we found empty! ATAK reads .pref files from /sdcard/atak/config/prefs/.

Now the question is: does ATAK auto-load .pref files from this directory on startup, or does it only load them when explicitly imported?

Looking at PreferenceManagementFragment:

  prefFileObserver = new FileChecker(PreferenceControl.DIRPATH);
  prefFileObserver.loadFiles();


  prefFileObserver.startWatching();

This sets up a file observer that loads existing preference files and watches for new ones. But since PreferenceManagementFragment is just a UI fragment that only appears when the user opens the preferences screen, I need to trace how ATAK actually loads
preferences during startup.

● Find ATAK startup preference loading flow
$ # How ATAK loads prefs on startup

◐ The ingestDefaults() method looks for a file named exactly defaults (no extension) in the config/prefs/ directory on every mount point. It loads it and then deletes it! This is perfect for our use case.

So the plan:

Create a file named defaults (no extension!) at /sdcard/atak/config/prefs/defaults
The file should be in the .pref XML format with atakGlobeModeEnabled = false
ATAK will read it on next startup, apply the settings, then delete the file
ATAK will start without the Cesium globe rendering I’m creating the XML file with the proper preference structure to disable the globe mode. But I need to double-check how loadSettings() actually processes this file—there might be a difference between the overloaded versions that affects the format or parsing. Looking at the implementation, both methods use the same underlying parser, so my XML format should work correctly. The parser extracts the name attribute from the preference element and remaps com.atakmap.app_preferences to the default preferences name,
which is exactly what I need. Let me write this file and restart ATAK to verify it works.

● ingestDefaults() loads a file named exactly defaults from /sdcard/atak/config/prefs/ on every startup, applies the prefs, then deletes it. Let me inject it:

● Push ATAK defaults pref file to disable globe mode
$ ADB=”adb -s adb-28031FDH30041N-wYOeFG._adb-tls-connect._tcp”

# Create the defaults pref file to disable globe mode

◐ Good news:

The defaults pref file was consumed (the directory is now empty) — ingestDefaults() loaded it and deleted it
ATAK process is NOT in the running apps list — it crashed again or didn’t start The logcat buffer doesn’t have ATAK entries because it seems the logcat buffer was cleared. Let me try a fresh launch with logcat streaming. Wait — the defaults file was consumed (deleted), which means ingestDefaults() ran successfully. ATAK must have started, loaded the preference, then crashed AFTER loading prefs but before we checked. Let me launch ATAK again and capture logcat more carefully this time.

● The defaults file was consumed ✅ — ingestDefaults() ran and deleted it. But ATAK still crashed. Let me capture logcat from the next launch:

● Launch ATAK and capture 25s of logcat
$ ADB=”adb -s adb-28031FDH30041N-wYOeFG._adb-tls-connect._tcp”
$ADB logcat -c 2>/dev/null

# Launch ATAK
$ADB shell am start -n com.atakmap.app.civ/com.atakmap.app.ATAKActivity 2>&1…
└ 56 lines…

◐ Two important findings from the logcat:

The defaults file was NOT found at /storage/emulated/0/atak/config/prefs/defaults — but it WAS at /sdcard/atak/config/prefs/defaults. There are TWO different paths being checked:- /storage/emulated/0/atak/config/prefs/defaults (mount point checked by
ingestDefaults)
- /sdcard/atak/config/prefs/defaults (where we pushed the file)
Wait, /sdcard/ is symlinked to /storage/emulated/0/ on Android… So they should be the same. The logcat shows the file wasn’t found at /storage/emulated/0/atak/config/prefs/defaults, but we pushed it to /sdcard/atak/config/prefs/defaults — and since those paths should be equivalent on Android, something’s off. ATAK appears to be checking multiple
storage locations including both internal and external storage, so the issue might be that ingestDefaults() is iterating over mount points and not finding the file where it expects it. Wait, I’m realizing the file might have already been consumed on the previous launch — ATAK found it, applied the preference to disable globe mode, then deleted it. So this run showing “no default config file found” is actually expected behavior. The preference
should already be stored in ATAK’s SharedPreferences database. Let me check if ATAK crashed again or if it’s still running by looking at the process logs and any new tombstones. I’m noticing something important in the logcat: there’s a page size mismatch warning for ATAK’s native libraries, which means they’re not 16KB aligned. This could be blocking startup or forcing the user to dismiss a dialog. I need to see what happens after the
configuration change line to determine if ATAK crashed or made it further this time.

● Progress! ATAK got much further — it reached ATAKActivity initialization. Let me check if it crashed after configuration change and get the full picture:

● Check for new tombstones and ATAK status after launch
$ ADB=”adb -s adb-28031FDH30041N-wYOeFG._adb-tls-connect._tcp”

# Check for NEW tombstone (newer than 11:31)

❯ At this point if you feel an emulator would help we may consider it.

◐ The user is asking if an Android emulator would help. Let me assess the situation:

ATAK 4.6.0 crashes on Android 16 (Pixel 7 Pro) due to std::invalid_argument: normal must be normalized in CesiumBridge_render — a Cesium 3D Tiles GL rendering bug
The globe mode preference (atakGlobeModeEnabled=false) was successfully injected but ATAK still crashes (possibly from a different crash after the first fix, or the same crash still)
The PageSizeMismatchDialog warning appears (16KB ELF alignment issue)
Since there’s no new tombstone and ATAK isn’t running, either the app crashed silently or the PageSizeMismatchDialog is blocking startup entirely — on Android 16, this dialog might be preventing the app from even reaching the point where it would generate a
crash log. For the emulator approach, an API 33 instance would sidestep both the Cesium crash and the 16KB page size issue, and ATAK 4.6.0 should run fine there. The real limitation is missing RF hardware and SDR capabilities, but it’d still be valuable for confirming the
plugin loads and the UI functions correctly without those dependencies. The core question though is whether that PageSizeMismatchDialog actually prevented ATAK from launching on the Pixel 7 Pro, or if something else is keeping it from running. Since there’s no new crash log but the process isn’t visible, I need to figure out if the
dialog is still blocking startup or if ATAK exited cleanly after the preference change. I’m weighing whether to set up an emulator with API 33 instead of continuing to debug the physical device—the emulator would eliminate the 16KB page size and Cesium issues
entirely, giving us a clean environment to test the plugin lifecycle. Let me verify we have the necessary Android SDK components available since ANDROID_HOME is already configured.

◐ Very interesting! ATAK is actually making significant progress:

Globe.create 2232x1027 dpi=356.0 — ATAK is creating the globe now!2. It’s getting past many initialization steps
But I see ReflectInterop: getPointer() failed for NativeGeometryModel — this is a warning, not fatal The key insight: ATAK is getting MUCH further now with globe mode disabled. The Cesium 3D tiles crash has been fixed by disabling globe mode. But there are issues:
W ReflectInterop: getPointer() failed for NativeGeometryModel — this is a compatibility issue between the Java API and native engine
The process is crashing after that point, so I need to check if there’s a new tombstone file to see exactly where it’s failing now. I should also look at the full logcat output after the ReflectInterop warning to trace the actual crash. On the bright side, we do have the AVD manager available, though we’d need to download system images to set up an emulator. For now, let me focus on
understanding where ATAK is dying with this new configuration.

● ATAK got much further! Globe.create 2232×1027 — it’s past Cesium now. But ReflectInterop: getPointer() failed suggests another native compatibility issue. Let me get more:

● Get full ATAK post-Globe.create logcat and check new tombstone
$ ADB=”adb -s adb-28031FDH30041N-wYOeFG._adb-tls-connect._tcp”

# Get full logcat from 20:15:47 onward for process 30309

awk ‘/GdalLibrary: XXX/{found=1} found’ | head -80…
└ 91 lines…

◐ More analysis needed. Looking at what’s happening:

ReflectInterop: getPointer() failed for NativeGeometryModel – These are WARNINGS, not fatal errors. ATAK handles these gracefully.
CesiumBridge: CesiumBridge_init w=1 h=1 ion=(none) local=http://10.0.2.2:8080/tileset.json — The CesiumBridge is STILL being initialized! Even with atakGlobeModeEnabled=false! This means the globe mode preference doesn’t prevent CesiumBridge from
initializing, it just might prevent the Cesium globe from rendering. The bridge initialized but failed to set up GL rendering due to no EGL context on the main thread, yet it still reports ready. Notably, there’s no new tombstone file—the ones from 11:31 are still there—so ATAK isn’t crashing with a native signal anymore. The
process disappeared from ps output, but I need to dig deeper into the logcat to see what actually terminated it. Looking at the sequence, ATAK reached CesiumBridge ready and ATAKActivity: configuration changed, then vanished. The culprit could be the PageSizeMismatchDialog that Android 16 shows for 4KB-aligned native libraries—it might have blocked the app and triggered
a timeout kill—or there’s another crash on a different thread, or the system killed it for some other reason. But I see the dialog was actually shown and ATAK continued past it, so that’s probably not the blocker. The real issue is that when running remotely via adb shell am start, the PageSizeMismatchDialog appears on screen but nobody’s there to dismiss it. On Android 16, the dialog warns about compatibility issues and requires user interaction to proceed or go back.
If left untouched, the app might hang or get killed by the system after a timeout. Looking at the evidence: the ps check 25 seconds later showed ATAK wasn’t running, but there are no new tombstones after the 20:15:45 launch (only old ones from 11:31), which rules out a crash from a signal. So ATAK was either killed by the system due to ANR or
OOM, exited cleanly on its own, or was terminated because of the unhandled dialog. I need to check the logcat after 20:15:47 to see what actually happened.

● Get ATAK logcat after CesiumBridge ready

◐ Excellent! ATAK is actually running and getting VERY far! D ATAKActivity: ATAK v4.6.0.5 (83077b35) r1771026621 starting up... — it’s properly initializing! The UI is being drawn with NavButtons and everything.

And I can see GLWidgetsMapComponent resized: 2232x965 — the map is rendering!

The ATAK process is gone from ps because… the PageSizeMismatchDialog was shown and the user (or system) dismissed it. Without a display interaction, the process might have been killed by the user closing the dialog with “Force Close” or the system killed it
after a while.

But wait, looking at those final log lines more carefully — the View layout warnings and NavButton positioning suggest ATAK was actually still running when those logs were written. The process might have been running under a different UID or the grep filter
missed it, but the ps -A | grep atakmap should have caught it if it was still alive. More likely the process terminated after the PageSizeMismatchDialog appeared.

Actually, the most probable scenario is that the dialog appeared on screen and the user tapped “Force Close,” which killed the app — this is a known issue on Android 16 with 4KB-aligned binaries. The AppWarnings log confirms the dialog was shown for
com.atakmap.app.civ, and that button would terminate ATAK immediately.

The good news is ATAK was actually running and rendering the UI successfully before being killed. To fix this, I can either rebuild the APK with 16KB-aligned native libraries, enable 4KB compatibility mode through device configuration, or dismiss the dialog
directly via ADB commands.
