Change device name in wifidirect on android

Question

When I discover peers to connect to, i can fetch the list in this method:

@Override
public void onPeersAvailable(WifiP2pDeviceList peers) {
    List<WifiP2pDevice> peersList = new ArrayList<WifiP2pDevice>(peers.getDeviceList());

}

WifiP2PDevice.deviceName returns the name set in the System Wifi settings on the WifiDirect page.

Lets say a user sets their nickname in my app to "John", is it possible to change the device name so when another device discovers it, the name will show up as "John"?

Answer 1

It uses hidden method. You can change the device name using the following code

Method m = manager.getClass().getMethod("setDeviceName", new Class[]     {channel.getClass(), String.class,
                    WifiP2pManager.ActionListener.class});
        m.invoke(manager, channel, newDeviceName, new WifiP2pManager.ActionListener() {

            @Override
            public void onSuccess() {
            }
            @Override
            public void onFailure(int reason) {
            }
    });
