Completness is all good, but screen remains completly black. 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. Currently, to draw on screen, I generate a framebuffer with a Renderbuffer for the GL_COLOR_ATTACHMENT0 using this code.I am trying to generate a frambuffer object and use stencil inside a native android application using the NDK (r5b).
