How to get information ( specially headset device name ) of bluetooth headset device in android

Question

I am creating an app where I need to display the name of connected bluetooth headset . My headset is switched on and connected to android device . I am routing phone audio to headset , but I am unable to display the connected headset name .

I tried with " getName () " method , but it returns another paired bluetooth mobile device which is not currently connected and switched off .

Need suggestions so badly .

UPDATE

I used this code . But unfortunately it returns an android bluetooth device name which is not currently connected , where my headset is still connected and I am able to route phone audio

            bluetoothManager = (BluetoothManager)      getSystemService(Context.BLUETOOTH_SERVICE);


        bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

        bluetoothAdapter.cancelDiscovery();

        Set<BluetoothDevice> getDevices = bluetoothAdapter.getBondedDevices();

        String remoteDevice = null;


        for (BluetoothDevice getDevice : getDevices) {

            //stringBuilder.append(getDevice);


            remoteDevice = getDevice.toString();

        }


        blueToothDevice = bluetoothAdapter.getRemoteDevice(remoteDevice);

    StringBuilder stringBuilder1 = new StringBuilder();

        stringBuilder1.append(blueToothDevice.getName());

Answer 1

I finally solved the problem . Previously I got all bonded devices with " getBondedDevices() " method from " BluetoothAdpter " class . But I fixed the problem by using "getConnectedDevices" method from the class " BluetoothProfile ".

My new code is below, which only shows the connected bluetooth headset device name which only connected to HEADSET profile .

   bluetoothManager = (BluetoothManager)      getSystemService(Context.BLUETOOTH_SERVICE);


    bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

    bluetoothAdapter.cancelDiscovery();

               bluetoothAdapter.getProfileProxy(this, listener, BluetoothProfile.HEADSET);

public final BluetoothProfile.ServiceListener listener = new  BluetoothProfile.ServiceListener() {
    @Override

    public void onServiceConnected(int i, final BluetoothProfile      bluetoothProfile) {



        final TextView txt = (TextView) findViewById(R.id.textView);


       List<BluetoothDevice> b = bluetoothProfile.getConnectedDevices();




        StringBuilder stringBuilder = new StringBuilder();

        for(BluetoothDevice getConnectedDevice : b){

            stringBuilder.append(getConnectedDevice.getName());


        }


    txt.setText(stringBuilder); 


    }

    @Override
    public void onServiceDisconnected(int i) {
        final TextView txt = (TextView) findViewById(R.id.textView);

        txt.setText(String.valueOf(i));
    }
};
