How to make a specific group owner in Wifi-Direct Android

I have an Wifi Direct Android Application which will run on two Phones.

When phone1 connects to phone2 , I want phone1 to act as a client and phone2 to act as a server.

I used this code:

if (info.groupFormed && info.isGroupOwner) {

           // start the server thread

   } else if (info.groupFormed) {

            // start the client thread
   }

But the problem is that , sometimes phone1 which has initiated the connection and I want it to act as a client , it sometimes acts as a GroupOwner, and the server thread is started on the client phone.

I want to make sure that phone2 always act as a GroupOwner and a server.

Well, what you can do is:

@Override
public void connect(final WifiP2pDevice device) {
    //obtain a peer from the WifiP2pDeviceList
    WifiP2pConfig config = new WifiP2pConfig();
    config.deviceAddress = device.deviceAddress;
    config.wps.setup = WpsInfo.PBC;
    config.groupOwnerIntent = 15; // I want this device to become the owner
    mManager.connect(mChannel, config, new WifiP2pManager.ActionListener() {
        @Override
        public void onSuccess() {
            //success logic
            Log.d(P2P, "connected to device " + device.deviceName);
        }

        @Override
        public void onFailure(int reason) {
            //failure logic
            Log.d(P2P, "unable to establish connection to device " + device.deviceName);
        }
    });
}

Note the config.groupOwnerIntent = 15; line. This tells WifiP2pConfig that we the device stating the connection is more likely to become a GroupOwner.

Hope it helps.

To set a peer as a client , not a GroupOWner eachtime , we have to assign:

config.groupOwnerIntent = 0;
