glDiscardFrameBufferEXT undefined in Android, is there an equivalent?

I am currently in the process of converting a framework (OpenGL ES 1.1, with extensions) to Android. Trouble is, the framework uses frame buffers, yet glDiscardFramebufferEXT returns an error that it is undefined.

My Android.mk uses -DGL_GLEXT_PROTOTYPES to get the GL extensions (anything with OES tag).

Is there a workaround for this? Or do I have to make Android specific changes here? (Or maybe I'm just missing something.)

(This framework is compatible with IOS, so I figured the GL code would be similar, if not the exact same.)

Thanks.

DiscardFramebuffer is a performance hint to the OpenGL driver: it can always be trivially removed or ignored without visible impact.

If the extension isn't available, then you can just remove the calls.
