title: Android bluetooth get connected devices
body: <p>How can I get a list of all connected bluetooth devices for Android regardless of profile?</p>
  
  <p>Alternatively, I see that you can get all connected devices for a specific profile via <a href="https://developer.android.com/reference/android/bluetooth/BluetoothManager.html#getConnectedDevices(int)" rel="noreferrer">BluetoothManager.getConnectedDevices</a>.</p>
  
  <p>And I guess I could see which devices are connected by listening for connections/disconnections via <a href="http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#ACTION_ACL_CONNECTED" rel="noreferrer">ACTION_ACL_CONNECTED</a>/<a href="http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#ACTION_ACL_CONNECTED" rel="noreferrer">ACTION_ACL_DISCONNECTED</a><em>...seems error prone</em>.</p>
  
  <p>But I'm wondering if there's a simpler way to get the list of all connected bluetooth devices.</p>
