How to Set User Device Name in WifiDirect? Is there any method to broadcast custom string using WiFiDirect without establishing connection?

Question

I am trying to BroadCast Long string using wifi direct. when peer clicks on the device I want to manipulate this string. So I decided to attach this string with device name but device name change code is not working.

I tried to use the reflection of WifiManger API. But this method is hidden cannot be accessed.

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

        @Override
        public void onSuccess() {
            Log.d(TAG, "Name change successful.");
            Log.println(Log.DEBUG,TAG, "Name change successful.");
        }

        @Override
        public void onFailure(int reason) {
            Log.d(TAG, "name change failed: " + reason);
        }
    });
} catch (Exception e) {
    Log.d(TAG, "No such method");
}

this try catch block trying to access this method and use it to set custom string BroadCastName as Device Name or Host name

I want Device's Default Name in WifiDirect to be Modified as String BroadCastName but I see no change.

why you use invocation instead of the public API? no such method is likely the `setDeviceName()`. — Martin Zeitler, May 21 '19 at 08:55
actually, I found this code on StackOverflow itself. My end goal is to change device name but I couldn't find any method to do so. — Onkar Mumbrekar, May 21 '19 at 09:00
