title: IBluetoothGatt.java in Android Studio
body: <p>I am trying to create a Bluetooth application in Android Studio.  I am using BluetoothGatt.java which requires IBluetoothGatt.java which is not in the sources folder in my android studio install.</p>
  
  <p>I downloaded IBluetoothGatt.java from grepcode and saved it in the sources folder (where BluetoothGatt.java is located) but when I try to import IBluetooth.java it can't find it.</p>
  
  <p>Is there a step I'm missing?  I've never done anything like this before so I'm not familiar with how to import a downloaded file into my project.</p>
