Lance, This looks like issue 6109 http://code.google.com/p/android/issues/detail?id=6109

Hopefully it'll make the next update to 2.1 -Dario On Jan 11, 4:31 am, Lance Nanek <lna...@gmail.com> wrote: > I'm getting exceptions when I try to use an interleaved buffer in > OpenGL with android.opengl.GLLogWrapper.
