You need to specify appropriate permissions and do the needful as mentioned below:

Permissions in manifest:

Receiver declaration in manifest:

NetworkCheckReceiver class file:

public class NetworkCheckReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
            Log.d("NetworkCheckReceiver", "NetworkCheckReceiver invoked...");


            boolean noConnectivity = intent.getBooleanExtra(
                    ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);

            if (!noConnectivity) {
                Log.d("NetworkCheckReceiver", "connected");
            }
            else
            {
                Log.d("NetworkCheckReceiver", "disconnected");
            }
        }
    }

}

Note:

Make sure you have working mobile cellular data connection. This receiver won't trigger if you don't have internet pack and you just switching on/off. You surely need to have working connection to test.
