How change the device name in WiFi direct p2p?

Question

Is it possibile to change the device name of WiFi direct through the code? I've tried to:

private WifiP2pDevice wDevice;
wDevice.deviceName = "newName";

But, obviously it doesn't work. Any idea?!

Is this question similar to the following? #27315698 As in you want to change the device name of the one broadcasting? – Idiotic

Following code use Reflection api of Java,It is less preferrable due to lack of efficiency but Android does not provide another way so, You can use it works with charm :

    try {
        Method m = wpm.getClass().getMethod(
                "setDeviceName",
                new Class[] { WifiP2pManager.Channel.class, String.class,
                        WifiP2pManager.ActionListener.class });

        m.invoke(WifiP2pManager wifimngr,WifiP2pManager.Channel wifichannel, new_name, new WifiP2pManager.ActionListener() {
            public void onSuccess() {
                //Code for Success in changing name
            }

            public void onFailure(int reason) {
                //Code to be done while name change Fails
            }
        });
    } catch (Exception e) {

        e.printStackTrace();
    }

This code works for me.

WifiP2pManager manager;
WifiP2pManager.Channel channel;
    try {
       manager = (WifiP2pManager)getSystemService(Context.WIFI_P2P_SERVICE);
        channel = manager.initialize(this, getMainLooper(), new WifiP2pManager.ChannelListener() {
            @Override
            public void onChannelDisconnected() {
                manager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
            }
        });
        Class[] paramTypes = new Class[3];
        paramTypes[0] = WifiP2pManager.Channel.class;
        paramTypes[1] = String.class;
        paramTypes[2] = WifiP2pManager.ActionListener.class;
        Method setDeviceName = manager.getClass().getMethod(
                "setDeviceName", paramTypes);
        setDeviceName.setAccessible(true);

        Object arglist[] = new Object[3];
        arglist[0] = channel;
        arglist[1] = devName;
        arglist[2] = new WifiP2pManager.ActionListener() {

            @Override
            public void onSuccess() {
                Log.d("setDeviceName succeeded", "true");
            }

            @Override
            public void onFailure(int reason) {
                Log.d("setDeviceName failed", "true");
            }
        };
        setDeviceName.invoke(manager, arglist);

    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    }

Tested it on Android 6.0.1 today - works great. Thank you. – Wadmal

it works, are there any risk for security? what about the intent broadcast with WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION? – Hypothec

Also tested on 6.0 today. works perfectly! big thanks. – Basically

Does this still work on latest android versions? – Afroamerican

Answer 3

if (action.equals(WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION))
{
    WifiP2pDevice device = intent.getParcelableExtra(WifiP2pManager.EXTRA_WIFI_P2P_DEVICE);
    // device.deviceName
}

this code works
