Answer 1

Use this in your receiver

<receiver android:name=".UpdateReceiver" >
        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
        </intent-filter>
    </receiver>

Your UpdateRecieiver

 public class UpdateReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {


      ConnectivityManager connectivityManager = (ConnectivityManager) 
                                   context.getSystemService(Context.CONNECTIVITY_SERVICE );
      NetworkInfo activeNetInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
      boolean isConnected = activeNetInfo != null && activeNetInfo.isConnectedOrConnecting();   
      if (isConnected)       
          Log.i("NET", "connecte" +isConnected);   
      else Log.i("NET", "not connecte" +isConnected);
    }
}

Answer 2

try out this function

public static boolean isInternetAvailable(Context context) {
            ConnectivityManager cm =
                (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo netInfo = cm.getActiveNetworkInfo();
            if (netInfo != null && netInfo.isConnectedOrConnecting()) {
                return true;
            }
            return false;
        }

and in the manifest

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

enjoy..
