Actually, after thinking about this for awhile, it may be best to call updateTexImage in rendering method instead (Renderer.onDrawFrame). There you know for sure underlying texture is created etc.

I have no experience in SurfaceTexture but I would expect workflow goes roughly as;
1. Implement SurfaceTexture.onFrameAvailable(..).
2. Once new frame is available trigger a runnable to be ran on render thread (GLSurfaceView.queueEvent(..)).
3. On render thread runnable call SurfaceTexture.updateTexImage().
This way you should be able to update texture in a way it shouldn't harm rendering - meaning texture is not altered during rendering. But as said, I haven't tried this myself yet, will try something like this as soon as I get my hands on a device running on API 14+ though.
