    // BluetoothAdapter.getDefault() throwing RuntimeException while not in
    // Activity
    // 
    // When I'm trying to get default bluetooth adapter while i'm NOT in
    // Activity, but in TimerTask (created inside Service) by using:
    // 
    // BluetoothAdapter.getDefaultAdapter();
    //
    // I get the following exception:
    // 
    // Exception while invoking java.lang.RuntimeException: Can't create
    // handler inside thread that has not called Looper.prepare()
    // My application do not have any activity - so is there any possibility
    // to get this adapter away from Activity?
    //
    // - Toland H, 23/02/2013
    // 
    // This appears to be a bug in Android and still exists in Android 4.0
    // (Ice Cream Sandwich)
    // 
    // To workaround this and be able to call
    // BluetoothAdapter.getDefaultAdapter() from a worker thread (e.g.
    // AsyncTask), all you have to do is call
    // BluetoothAdapter.getDefaultAdapter() once on the main UI thread (e.g.
    // inside the onCreate() of your current activity).
    //
    // The RuntimeException is only thrown during initialization, and
    // BluetoothAdapter.getDefaultAdapter() only initializes the first time
    // you call it. Subsequent calls to it will succeed, even in background
    // threads.
    //
    // - user2304686, 21/04/2013
    // 
    // calling BluetoothAdapter.getDefaultAdapter() in the UI thread works,
    // but is not very practical. I have tried the workaround with a fake
    // Activity, but since I hate such workarounds, I decided to READ what
    // the error message really says and it is nothing more than that the
    // thread didn't call Looper.prepare().
    // So calling Looper.prepare() just before calling
    // BluetoothAdapter.getDefaultAdapter() should solve the problem
    // anywhere, not just in a UI thread.
    // Works fine for me so far.
    //
    // - Flipper, 02/10/2013
    // 
    // Beware of a gotcha that exists in 2.3.x, but which has been fixed in
    // 4.x: if you call BluetoothAdapter.getDefaultAdapter() on any thread
    // other than the main application thread, that thread must call
    // Looper.prepare() and also subsequently Looper.loop().
    // Failing to do so will cause at least one problem that I ran into:
    // accept() will succeed the first time you try to connect, but then not
    // succeed on successive attempts, even after using close() on the
    // ServerSocket.
    // This happens because in the older implementation of BluetoothAdapter,
    // the cleanup of the SDP entry occurs by way of a message posted to a
    // handler created on the thread where getDefaultAdapter() is called.
