The test application won't compile with the given dependencies

[albintornqvist]

After following the steps in the readme of the Android project i can't seem to get the project to build properly. The readme suggests using the latest version of NDK but after some digging i found out that I have to use version 17 of NDK to be able to compile. (Maybe the readme should specify the version?). When using NDK 17 compilation goes further but i still get an error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':MapboxGLAndroidSDK:transformNativeLibsWithMergeJniLibsForDebug'.
> More than one file was found with OS independent path 'lib/armeabi-v7a/libmapbox-gl.so'"

I tried adding the following to get rid of this error:

android {
    packagingOptions {
        pickFirst 'lib/armeabi-v7a/libmapbox-gl.so'
    }
}

This makes the project compile but the test app crashes as soon as i run it on the emulator (using a Pixel 2 XL on API 26 emulator).
Crash log:

2018-11-13 13:44:08.904 19864-19864/com.mapbox.mapboxsdk.testapp A/libc: /Volumes/Android/buildbot/src/android/ndk-r12-release/ndk/sources/cxx-stl/llvm-libc++abi/libcxxabi/src/abort_message.cpp:74: void abort_message(const char *, ...): assertion "terminating with uncaught exception of type jni::PendingJavaException" failed

Am I missing something here? Some dependency version not specified in the readme? Does anyone recognize the issue?

Steps to reproduce

1. Checkout the tag android-v6.6.7 or android-v6.0.1 and use NDK 16 (not sure if correct version)
2. Setup all the dependencies and follow the steps described in the readme.
3. Build the test application MapboxGLAndroidSDKTestApp for device or emulator (or run 'make apackage' which also produces the compilation error)

Expected behavior

The project compiles and the app runs on the device/emulator.

Actual behavior

Build error or crash.

Configuration

Android versions: Android 8.0, API 26
Device models: Samsung SM-G955F or Emulator: Pixel XL 2
Mapbox SDK versions: 6.0.1 or 6.6.7
Android Studio version: 3.2.1
OS version: MacOS Mojave 10.14

Sorry, NDK r18 is currently blocked on the removal of <experimental/optional> in the libc++ used by NDK r18 (#13049).

We haven't seen multiple versions of libmapbox-gl.so being produced; that looks like a bug. Did you try clearing the build directory after you downgraded the NDK? You can run make clean to do that.

/Volumes/Android/buildbot/src/android/ndk-r12-release points to a really old NDK version. Please use a newer version. We're currently successfully using r17b.

[albintornqvist]

Ah, I'll keep my eyes on #13049 then!

I tried 'make clean' and also clean build folder in Android Studio.
I'm not sure why the stack trace points to a ndk-r12-release (could it be a dependent lib that is built with r12?...) since I'm sure I installed NDK r17c. As you can see in the screenshot i provided, Android Studio seems to have picked up that version as well. However r17c is the only version of r17 that I can find, looking at https://developer.android.com/ndk/downloads/older_releases and spending some time googling... Have you tried this version as well? or do you know how to get a hold of r17b?

[albintornqvist]

I found a version of r17b after some searching but I am experiencing the same issue with that version as well unfortunately (can not compile due to more than one file called libmapbox-gl.so).
I successfully compiled from tag android-v5.5.0 using NDK r16b. But i still get the same crash when running the test app. Stepping through the startup process of the app it seems like the instantiation of NativeConntectivityListener is causing the crash. When crashing, the app stops on a breakpoint producing the following stack trace in Android Studio:

[tobrun]

@albintornqvist your setup matches my setup locally.

More than one file was found with OS independent path 'lib/armeabi-v7a/libmapbox-gl.so'"

Can you execute a make clean in the root folder of this project to clear out any remaining artifacts? What happens if you execute make android? You mention using ndk 17, but stacktrace in OP indicates ndk 12 for some reason in /Volumes/Android/buildbot/src/android/ndk-r12-release/.

[albintornqvist]

The ndk 12-stacktrace sure is suspicious. I tried cloning the Mapbox repo fresh in a new folder and now it works like a charm. I should have tried that earlier of course... I'm guessing I had old compiled files somewhere in my previous local repo that wasn't deleted when running make clean.

Thank you for taking the time to answer my questions and pinpointing the problem!

[kkaefer]

Glad it works for you now!
