Apk (kivy's example 3d rotation monkey)crashes on start

Versions:

• Python: python3
• OS: Android
• Kivy: v1.11.1
• Kivy installation method: buildozer

On Linux(Ubuntu) and Windows 7 application works fine, but when I compile in apk and try to run on Android phone its crashes! Another app without shader(OpenGL2) works on android after compilation in apk, but this one don’t( Maybe the problem in shaider? How to configurate it? In buildozer.spec I add sgls, and obj extensions

This what adb logcat shows:

[AndiEcker]

Wrote a glsl tester app - tested on Linux and Android.

While playing with shaders I experienced that even simple shaders that run fine on Linux are crashing on Android in vbo.so (w/o any python traceback) if the texture did not get fetched within the pixel/fragment shader.

So the good news is that I got all of them running by adding the following statement into the shader code::

vec4 tex = texture2D(texture0, tex_coord0);

So even if you do not use the texture in your shader it seems that you have to fetch it at least to prevent the vbo.so crash.

Can you tell in which module - need to add this line of the rotating monkey code ?
