Hello, I am optimizing an OpenGL-based application ported from that other major mobile OS and find that I cannot successfully access the GL context from anything other than the rendering thread of GLSurfaceView. What I CAN do on other platforms is upload my single (and large) texture to GL prior to needing to render the texture itself. This is a 640x480 8-bit RGB texture that takes some time to upload to the chip and needs to be done every time I realize a new frame of animation from the background system memory buffer. I'm sure you can appreciate the savings in execution time if I can perform this upload from another thread when I have nothing left to do but wait for GLSurfaceView's rendering thread to call me. All is synchronized safely as evidenced by the successful release of this software using this very same technique on that-other-platform-that-shall-not-be named. Things are very smooth and zippy on that platform, but Android currently suffers by comparison. Is there any way to do this?
