ANativeWindow_lock returns error -22

[David Seabolt]

When I try to lock the window I get an error -22, and then I receive output: E/BufferQueue(  180): [SurfaceView] connect: already connected (cur=1, req=2)

I'm attempting to lock the surface of a subclassed GLSurfaceView, and I'm attempting to draw to that surface without going through EGL, in the hopes that I can just blit a loading screen texture while the EGL thread is loading textures.

Is such a thing even possible?

I have the exact same question.

Did you manage to find any workaround for this?

[David Seabolt]

I couldn't find an acceptable workaround. It seemed to be a threading issue fighting with OpenGL

You cant lock a GLSurfaceView because EGL is already taking "ownership" of the Surface.

You need to use a simple SurfaceView.
