Android BluetoothDevice notify of deleted instant messaging states

Problem: I get a notification when a Bluetooth device connects or becomes paired. However, I don't know how to get notifications when the device is unpaired. How can I know how my application recognizes when it is unpaired with my device?

Example: Suppose I connect my tablet and my Android phone via code. My broadcast receiver will register the intent ACTION_BOND_STATE_CHANGED

and let me handle it, but I want to. Now if I want to turn off my tablet, I don't get a notification on my phone that the device has become unpaired. If I checked, device.getBondState()

for the device after it was unpaired, it is BOND_BONDED

(which clearly does not match) I can get it to recognize that it is unpaste again after trying to connect to the unpaired device, then the app crashes and then when I turn it back on application, only then will it recognize it as unpaired.

Script: I have BroadcastReceiver

registered to listen on intents called by BluetoothDevice

getActivity().registerReceiver(broadcastReceiver, new IntentFilter(BluetoothDevice.ACTION_FOUND));
getActivity().registerReceiver(broadcastReceiver, new IntentFilter(BluetoothDevice.ACTION_BOND_STATE_CHANGED));
getActivity().registerReceiver(broadcastReceiver, new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED));
getActivity().registerReceiver(broadcastReceiver, new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED));

      

        
        
        
      

    

I handle these actions with this BroadcastReciever

:

final BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        System.out.println("ACTION: "+ action);
        // When discovery finds a device

    if (BluetoothDevice.ACTION_FOUND.equals(action)) {
        list();

        // Get the BluetoothDevice object from the intent
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        System.out.println("FOUND: " + device.getName() + " STATE: " + device.getBondState());
        mapInput(device);

        // Add the name and the mac address of the object to the array adapter
        BTSimpleAdapter.notifyDataSetChanged();
    } else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) {
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        System.out.println("UPDATE Name " + device.getName() + " Value " + device.getAddress() + " Bond state " + device.getBondState());
        for (Map<String, String> entry : data) {
            if (entry.get("Name").equals(device.getName()) && entry.get("Value").equals(device.getAddress())) {
                if (device.getBondState() == BluetoothDevice.BOND_NONE) {
                    entry.put("Paired", "Unpaired");
                } else if (device.getBondState() == BluetoothDevice.BOND_BONDING) {
                    entry.put("Paired", "Pairing");
                } else {
                    entry.put("Paired", "Paired");
                }
                BTSimpleAdapter.notifyDataSetChanged();
            }
        }
    }
}
};
