How To Solve Discovering Other Device Via Wi-fi (android Api)?

recently I follow the steps given from Developer.Android.Com But it seems i have a few luck over there. I tried to discover the available peers nearby, put 'em into the arraylist b

Solution 1:

I guess you did't add PeerListListener to your activity. so it won't reply.

you can try to implement PeerListListener in your activity

publicclassChat1ActivityextendsActivityimplementsWifiP2pManager.PeerListListener

and override onPeerAvailable method in your activity

@OverridepublicvoidonPeersAvailable(WifiP2pDeviceList peers) {

   //put your code here

  }

and change requestPeers method in your Receiver

 if (mManager != null) {
            mManager.requestPeers(mChannel, mActivity);
 }

Hope this help!!

Solution 2:

Have you check whether your device support Wifi Direct? Having a rom > 4.0 does not means it has wifi direct hardware support. Try to check that with PackageManager's API: http://developer.android.com/reference/android/content/pm/PackageManager.html#hasSystemFeature(java.lang.String)
