I have no problem creating two separate GL contexts. It works and no errors are generated (tested on G1 (1.6) and Milestone (2.1)). But the problem is that resources sharing between contexts does not work as it is described in GLES 1.0 specification. So I am not sure does Android OGL implementation conform to GLES spec?
Thanks.
