I have an Android project that builds an AAR file library. When I include this AAR file in my Godot (v3.5.2) project and export it as an Android APK, the program crashes when I call a function in Godot that results in the following Kotlin code being run:
val lsh = LicensingServiceHelper(godot.activity as Activity, "<REDACTED>")
My LicensingServiceHelper.java is as follows:
public class LicensingServiceHelper {
private static final String TAG = "LicensingServiceHelper";
private final Activity context;
private final String publicKey;
private LicensingServiceCallback callback;
private ILicensingService licensingService;
private ServiceConnection serviceConnection =
new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder binder) {
licensingService = ILicensingService.Stub.asInterface(binder);
Log.d(TAG, "Service connected");
}
@Override
public void onServiceDisconnected(ComponentName name) {
licensingService = null;
Log.d(TAG, "Service disconnected");
}
};
public LicensingServiceHelper(Activity activity, String publicKey) {
this.context = activity;
this.publicKey = publicKey;
}
}
An excerpt of my logcat is as follows:

I can provide more of my project files if needed.
It seems the issue was related to my Godot Android plugin's .gdap file not being set up correctly.
Changing GodotPlayGamesServices.gdap from
[config]
name="GodotPlayGamesServices"
binary_type="local"
binary="GodotPlayGamesServices.release.aar"
[dependencies]
remote=["com.google.android.gms:play-services-games:23.1.0", "com.google.android.gms:play-services-auth:20.5.0", "com.google.android.gms:play-services-location:21.0.1", "com.google.code.gson:gson:2.8.9"]
to
[config]
name="GodotPlayGamesServices"
binary_type="local"
binary="GodotPlayGamesServices.release.aar"
[dependencies]
local=["licensingservicehelper-release.aar"]
remote=["org.bitbucket.b_c:jose4j:0.9.6", "com.google.android.gms:play-services-games:23.1.0", "com.google.android.gms:play-services-auth:21.1.1", "com.google.android.gms:play-services-location:21.2.0", "com.google.code.gson:gson:2.8.9"]
and placing the licensingservicehelper-release.aar file in the Godot project's android/plugins directory caused the APK to run without crashing when exported in Godot.
