Well the simple case works. I check after each call and compiling works.. creating the program works...everything return success. But when linking it just remains in the native call, never to return.
I suspected that creating the shaders and program in one requestRender() and then linking in the next one could be the issue but it isn't. Anyway even if there is something wrong with my shader code it still should return immediately. This sounds like an Android bug to me....
