This is a small tic-tac-toe game (michi, in Peru) prepared for an intro to android presentation which demonstrates several concepts. It is released under the GPL in hopes that you find it helpful, but make no promise that it is useful.
1) Linear layout, with embedded linear layouts were used to demonstrate basically how to lay out a screen anyway you would like. (Though not promising to be the most efficient).
2) A very Strong MVC pattern is shown. 'View' and 'Model' do not talk in this implementation. From my perspective, the benefit to this design is the ease in which you can write unit tests to exercise your application without fancy test software or hardware. Further architecture refinement is also demonstrated where the code for the view is segmented to specific input and output classes.
3) Controller is basically a 'facade controller' using a 'strategy pattern' to handle different algorithms when a human is playing a human vs. a human playing a computer.
4) Sample code for embedding advertisements is included.
