WiFi Direct on Android not working properly

Question

I am trying to develop an app using wifi direct in android Jelly Bean 4.1.1. If p2p is enabled I immedialtely call

mManager.discoverPeers(mChannel, actionListene         


        

Answer 1

You should use the Discovering peermethod:

manager.discoverPeers(channel, new WifiP2pManager.ActionListener() {
    @Override
    public void onSuccess() {
        ...
    }

    @Override
    public void onFailure(int reasonCode) {
        ...
    }
});

If the discovery process succeeds and detects peers, the system broadcasts the WIFI_P2P_PEERS_CHANGED_ACTION intent, which you can listen for in a broadcast receiver to obtain a list of peers. When your application receives the WIFI_P2P_PEERS_CHANGED_ACTION intent, you can request a list of the discovered peers with requestPeers().
