title: Appcelerator titanium - drag and drop
body: <p>I am new to Appcelerator Titanium and would like to ask, is there a way to implement drag and drop in appcelerator titanium for android? I tried the example here <a href="https://github.com/mcongrove/TiDrop" rel="nofollow">https://github.com/mcongrove/TiDrop</a>
  but it is not working properly on android, when i click on the box, i get the following runtime error:
  Type Error: Cannot read property "y" from null (file:///android_asset/Resources/TiDrop.js#34). can anyone help me?</p>
