For Android in this mini game the monkey catches nice bananas and coconuts.
It was somewhat more problematic to create the layout in XML compared to the small game engine and controls.
Maybe we can rewrite the code more object-oriented because it is rather procedural at this time. The game is open for testing in an open alpha and the source is available at my github.
