Classcaseexception On Gl11extensionpack. Rendering To Texture On Opengl Android

I'm trying to render to a texture (really thought it would be easier than this!) I found this resource: which seems to be exactly what I want I'm getting a ClassCastException howev

Solution 1:

Calling setDebugFlags on a GLSurfaceView to wrap the GL instance has/had the unfortunate sideeffect to not implementing all GL* interfaces. Unfortunately the issue does not state in which version this is fixed.
