Hello,
Activity.onCreate() runs on application's main thread which is not
associated with a GL context, hence the error message.
The usual way is to have a rendering thread which you can either
associate with a GL context yourself by using EGL calls, or you can
have the Android framework help you with it if you use GLSurfaceView.
The latter is simpler if you are no expert (and given the somewhat
unpredictable behaviour of EGL on Android). Check this out for a good
explanation how to get going with GLSurfaceView:

Hi,
I just met a issue of glGenTextures. I wrote the below codes on
Activity.onCreate() function
int[] mTextureNames = new int[1];
GLES20.glGenTextures(1,mTextureNames,0);
SurfaceTexture mSurfaceTexture = new
SurfaceTexture(mTextureNames[0]);
but mTextureNames[0] is always 0 and got the log call to OpenGL ES API with
no current context (logged once per thread). I think i may need to do some
initialization work before calling the source code. Would someone help to
tell me what's the steps ? Thanks a lot!
