I'm playing with SDL on android, and did notice a problem in latest sources ( branch "default" ) :
SDL/src/render/opengles/SDL_glesfuncs.h:10: error: 'glDrawTexiOES' undeclared (first use in this function)
SDL/src/render/opengles/SDL_glesfuncs.h:10: error: (Each undeclared identifier is reported only once
If it can help you win some time here is the fix, applied to the "Android.mk" file :
LOCAL_CFLAGS += -D GL_GLEXT_PROTOTYPES
