OpenGl is rendered directly to the bitmap (without any representation)

I need to apply some pixel shaders to a bitmap (using OpenGL) and send the result to the server. The rendering is supposed to be done in the background, so I cannot create a GLSurfaceView for this purpose. So my question is: is it possible to render OpenGL on Android without using GLSurfaceView? How to render directly to a bitmap, or canvas or some kind of buffer / array? Or maybe it is possible to use some GLSurfaceView dummy?

This SO post contains a link to the anddev post . Down a bit, someone created a PixelBuffer class that reuses the GLSurfaceView.Renderer interface, but other than that, only EGL.

It looks like you want to render the frame buffer object (i.e. directly to the texture). It is definitely possible. Just do a search for an answer here or on the Internet. I found this one, not too hard. I am not sure if you are using GL ES 1.1 or 2.0.

It also looks like APIDemos in the SDK has a sample for 1.1
