title: Google Glass GDK: How to Communicate with Android Device
body: <p>I'm looking for a way to send data between my Android Device and Google Glass that doesn't rely on Cloud API's.  Is this supported?  I see the Bluetooth connections in the My Glass app, which makes me think it can be done.  Is there an example source code that shows how this is done?  Or do I have to decompile the MyGlass app to figure it out?</p>
  
  <p>Is there a preferred method for doing this kind of data transfer?  Ideally I'd like to transfer data in both directions.</p>
