title: connect to device with Bluetooth address on String
body: <p>I am doing an Android App and where I have the MAC of another device as a string (17 characters long) and need to use that one in order to connect to that device (thread that initiates a Bluetooth connection).
  I've been playing around with it all afternoon and can't figure out how to do it. The problem is that it doesn't allow me to set the BluetoothDevice equal to a string. 
  Is there a way that this can/has to be done?</p>
  
  <p>(decided not to put any of my attempts here as code, seeing how they were full of errors)</p>
  
  <p>It has to communicate with another tablet that is running the exact same application. I looked through <a href="http://developer.android.com/guide/topics/connectivity/bluetooth.html" rel="noreferrer">this</a> page earlier and most of my app is based on that. My main problem is when using the ConnectThread example, </p>
  
  <p>I have a string with the MAC address, how do I connect to that MAC?</p>
  
  <p>Any help would be highly appreciated,</p>
