Hello List

while trying to understand the basics about SDL2.0 on Android
I have combined the SDLActivity example and the showimage.c example from SDL_image.
It is successful in that it does start and creates a window on the Android (both emu and real device)
but so far I can't get it to show the image in the SDL window.
the draw_background function however works fine.

I don't know what the problem is or if SDL_RenderCopy should actually show the image?

All Input Welcome!
