title: What is IBluetooth?
body: <p>I am new to android development platform.
  I came across a line of Code</p>
  
  <pre><code>IBluetooth bluetoothProxy = BuetoothAdapter.getDefaultAdapter().getBluetoothService(null);
  </code></pre>
  
  <p>in Bluetooth Socket.java class.</p>
  
  <p>It will be great to know what is exactly happening behind the scenes.</p>
