Android export on Google Play crash report: `UnsatisfiedLinkError` for `libgodot_android.so`

[wangdong20]

Godot version

3.4.3

System information

MacOS 12.1, Mac Pro, GLES2

Issue description

I just released game on Google play which is exported from Godot. In order to support low end device, I choose to support GLES2. It does work on my Android phone and passes the alpha test on Google play console but got crashes from Google play console statistics. Here is the crash log and device information:

It seems to fail loading libgodot_android.so here: https://github.com/godotengine/godot/blob/0ae6150d8eed297497544c007405720c7307792a/platform/android/java/lib/src/org/godotengine/godot/GodotLib.java#L44-L46

Can you check that your AAB properly contains the libgodot_android.so library for all the ABIs that you support?

ABI: arm64-v8a, armeabi-v7a, armeabi

Seems like armeabi is still reported as a supported secondary ABI even though it's no longer supported by Google Play: https://developer.android.com/ndk/guides/abis

I wonder if for some reason this device would wrongly attempt to load the armeabi library (which we don't provide, and can't even build anymore) instead of arm64-v8a?

I just set the arm64-v8a, armeabi-v7a true on Godot android export setting.

Another user (Dan_SCE) reported the same issue last week on the contributors chat:

@wangdong20 Do you do a custom build with additional plugins?

I'm not familiar with Java and Android lib loading but it's worth noting that UnsatisfiedLinkError may also mean that even though libgodot_android.so is present, one of its dependencies cannot be loaded (and then libgodot_android.so cannot be loaded either). I.e. this may not be a "file not found" error but an actual dependency issue.

Here are the dependencies for lib/arm64-v8a/libgodot_android.so in 3.4.3:

 0x0000000000000001 (NEEDED)             Shared library: [libc++_shared.so]
 0x0000000000000001 (NEEDED)             Shared library: [libOpenSLES.so]
 0x0000000000000001 (NEEDED)             Shared library: [libEGL.so]
 0x0000000000000001 (NEEDED)             Shared library: [libGLESv3.so]
 0x0000000000000001 (NEEDED)             Shared library: [libGLESv2.so]
 0x0000000000000001 (NEEDED)             Shared library: [libandroid.so]
 0x0000000000000001 (NEEDED)             Shared library: [liblog.so]
 0x0000000000000001 (NEEDED)             Shared library: [libz.so]
 0x0000000000000001 (NEEDED)             Shared library: [libdl.so]
 0x0000000000000001 (NEEDED)             Shared library: [libm.so]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so]

(Found with <android-ndk>/21.4.7075529/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-readelf -d lib/arm64-v8a/libgodot_android.so)

Which are the ones we set there: https://github.com/godotengine/godot/blob/0ae6150d8eed297497544c007405720c7307792a/platform/android/detect.py#L362

Worth noting, libGLESv3.so as a hard dependency might seem weird, but AFAIR it's provided as a stub on all Android devices even if OpenGL ES 3.0 is not supported.

How can I check the AAB properly contains the libgodot_android.so library for all the ABIs that I support?

You can unzip the generated AAB and inspect the contents to see if both libgodot_android.so and libc++_shared.so are present in the lib/<abi>/ folders.

[wangdong20]

I made a custom build with admob plugin.

Just unziped the AAB file and both libgodot_android.so and libc++_shared.so are presented in the lib/<abi>/ folders.

And only after I wrote everything above, I noticed that the error report came from a version downloaded from a third-party resource, not from Google play... And now I do not know how reliable this report is at all.

one year later 3.5.1 project target SDK 32 uses custom build and custom export template with encryption key. on my testing devices works good..

google crosshatch (Pixel 3 XL) Android 12 (SDK 31) both lib// contains libc++_shared.so and libgodot_android.so
