Here's a code snipplet for the framebuffer creation. So, I've been coding lots of gl code in my c++ native libs and havent got through any problem except for this. Target device is running froyo 2.2, supporting OpenGL ES 2.0. It enables depth testing, sets the clear color toīlack, and clears the color and depth buffers.I am trying to generate a frambuffer object and use stencil inside a native android application using the NDK (r5b).
