Viewing changes to src/client/android/android_client_buffer.h

android drivers have an interface for the drivers to obtain a strong reference to the native window type. Allow the drivers to acquire this strong reference to the buffer backing their texture/fbo.

Approved by PS Jenkins bot, Robert Ancell.
