After the update to Android MapBox SDK 4.1.0/4.1.1 my app crashes on Android emulator with:
E/mbgl: [Shader]: Vertex shader fill failed to compile: precision
For those using the emulator:
This can be fixed by changing your emulated graphics to Software - GLES 2.0 in your AVD settings. This is not ideal, but it will work (and is still much faster than emulating an ARM device).
Software - GLES 2.0
I suspect this is emulator specific.
