title: Android : GameController support
body: <p>Apologies if this is not the place to ask this question.</p>
  
  <p>I have started writing an Android 3D framework where I want to support game controllers / gamepads.  I have added the MOGA SDK but this has got me thinking that I will need to go about adding every game controllers SDK, this seems a little heavy, plus hard to test.</p>
  
  <p>What do other Android Game developers do about this?  Android seems to have a API for USB controllers but not for Bluetooth.</p>
