title: Android game development
body: <p>I want start develop games on Android.
  I'm yet an android app developer but I never develop a game.
  Can you help me for understand how start. It is better to use an external development suite like Unity 3d or is possibile to develop games just with Android Studio and SDK like the normal apps?
  The game I want to develop is simple, just a sprite and a backgroud. The sprite can move and jump.</p>
  
  <p>Thank you</p>
