Multicast Support in Android 2.2?

Does the Android 2.2 media framework support IG开发者_JAVA技巧MP/Multicast? If yes, can anyone guide how we can do that?

It is quite simple:

1. Inform the wifimanager that your app need to receive multicast:

   WifiManager wifi = (WifiManager)getSystemService( Context.WIFI_SERVICE );
   MulticastLock mcLock = wifi.createMulticastLock("mylock");
   mcLock.acquire();
   

2. Create the socket:

   InetAddress group = InetAddress.getByName(MULTICAST_ADDRESS);
   MulticastSocket s = new MulticastSocket(MULTICAST_PORT);
   s.joinGroup(group);
   

It appears that Multicast support in Android is not as solid as some of use might hope. See http://codeisland.org/2012/udp-multicast-on-android/

Ie whether it actually works out or may be device dependent. It is not working on my Nexus5.
