Just for fun, I recently wanted to learn Android programming and I have just finished a small (and not very original...) game which is available on Google Play.
You can get it for free (no ads, no in app purchase) here: https://play.google.com/store/apps/details?id=com.embarcadero.GemGenie
The app is a classic match 3 casual game (à la Bejeweled or Candy Crush), but obviously much more basic. Still I find it enjoyable so if you feel like it, why don't you try to beat the high score :-)
Here are a few screenshots:
