Android - when I click on REFRESH button it always goes to onFailure

Question

I'm trying to create a Mancala game. I'm doing a Wifi-Direct, but everytime I'm clicking on REFRESH button, it goes to onFailure method. The purpose of the refresh button is to discover new devices near me, but unrotuantely I can't find any devices because it's going to onFailure method.

What can I do?

public class wifiLoginScreen extends AppCompatActivity {

    private WifiP2pManager mWifiP2pManager;
    private WifiP2pManager.Channel mWifiP2pChannel;
    private BroadcastReceiver mReceiver;
    private boolean mWifiDirectEnabled;

    private ArrayAdapter<String> mPeersAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_wifi_login_screen);

        // Initialize WifiP2pManager and WifiP2pManager.Channel objects
        mWifiP2pManager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
        mWifiP2pChannel = mWifiP2pManager.initialize(this, getMainLooper(), null);

        // Initialize the BroadcastReceiver to listen for Wi-Fi Direct events
        mReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String action = intent.getAction();

                if (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) {
                    // Wi-Fi Direct state has changed
                    int state = intent.getIntExtra(WifiP2pManager.EXTRA_WIFI_STATE, -1);
                    mWifiDirectEnabled = (state == WifiP2pManager.WIFI_P2P_STATE_ENABLED);
                } else if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {
                    // The list of available peers has changed
