Working with NDK

For the "GL Recorder" activity can the rendering be done in native C++ and use the rest of the implementation as is?

E.g:

GLES20.glBindFramebuffer(GL_FRAMBUFFER, javaFBO);
nativeRender(...);
GLES20.glBindFramebuffer(GL_FRAMEBUFFER, 0);
drawToScreen();

Great job on this sandbox, learning a lot from it!

Thanks,
Cristina

Yes.

The Android EGL/GLES Java-language implementation is a thin wrapper around the native implementation. All of the interesting state is in native thread-local storage. Whatever context and surface you set up from code written in Java will be used by the native rendering calls.
