Android search for bluetooth devices

Question

I am trying to find the available Bluetooth devices.

This is my OnClickListener which is called when the user tries to search for the available devices.

View.OnClickListener OnSearchDevices = new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            //Toast.makeText(context, "Search Devices", Toast.LENGTH_LONG).show();
            Log.d("Discovery", "Started");
            listOfDevices.clear();
            label.setText("Searching Available Devices...");
            label.setEnabled(false);
        }
    };

I have also registered a BroadcastReceiver.

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();

            // When discovery finds a device
            if (BluetoothDevice.ACTION_FOUND.equals(action)) {
                // Get the BluetoothDevice object from the Intent
                BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                Log.d("DeviceList" , device.getName() + "\n" + device.getAddress());
                MyBluetoothDevice tempDevice = new MyBluetoothDevice();
                tempDevice.setDeviceAddress(device.getAddress());
                tempDevice.setDeviceName(device.getName());
                listOfDevices.add(tempDevice);
                mListAdapter.notifyDataSetChanged();
                //  discovery is finished
            }
            else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {

                Log.d("Discovery","Finished");
                label.setEnabled(true);
                if(listOfDevices.size() == 0)
                {
                    label.setText("No Devices Available!");
                    label.setTextColor(Color.parseColor("#FF0000"));

                }
                else
                {
                    label.setText("Available Devices");
                }

            }
        }
    };

But nothing happens. It does not show anything. Please help.

Looks like you are missing the call to mBluetoothAdapter.startDiscovery().

That would explain why you are not getting any results, because the adapter doesn't even start searching for the devices.

Your code looks fine to me otherwise.
