Android plugin crashes when built as AAR but not jar

Hi,

In order to comply with Google's messaging requirements for runtime permissions we've had to implement a plugin that overrides the main Unity activity to trigger a custom activity on startup to ask for the WRITE_EXTERNAL_STORAGE permission, before Unity starts up. If I just grab classes.jar and AndroidManifest.xml for the plugin after building in Android Studio this works great. If however I use the AAR output (from the same build), I get this crash:

Caused by: java.lang.NoSuchMethodError: no non-static method "Lcom/unity3d/player/UnityPlayer;.initializeGoogleVr()Z"

Does anyone know what causes this/how to fix it? I need to add localisation so would prefer to use an AAR if I can.

Thanks!

 

Is initializeGoogleVr() a static method? If not, try ' Call("initializeGoogleVr") ' instead of ' CallStatic ("initializeGoogleVr") ' in your c # script.
