title: BluetoothAdapter.startLeScan is not working with filter
body: <pre><code>private UUID[] RX_SERVICE_UUID = new UUID[1]; 
  RX_SERVICE_UUID[0] = UUID.fromString("0000e4eee-1112-1111-1111-14addb4as215");
  </code></pre>
  
  <p>when i am using the function with UUID <code>mBluetoothAdapter.startLeScan(RX_SERVICE_UUID,mLeScanCallback)</code> method. It is not scanning the device when i am using without UUID means <code>mBluetoothAdapter.startLeScan(mLeScanCallback)</code> then it is scanning the device. Please suggest.</p>
