Hi Robert,
Great Website!!
I've started programming for Android two weeks ago.
I've read an awful lot about java & android (I had much experience with other languages but not java and not game development).
After the "Hello Android" example I started my own Tetris clone as a practice.
I have created the game as SplashActivity -> MenuActivity -> GameActivity -> GameView -> GameThread. (start with a splash screen, than show a menu with a button for starting the game)
