- public class ConnectionChangeReceiver extends
BroadcastReceiver- {
- @Override
- public void onReceive( Context context, Intent intent )
- {
- ConnectivityManager connectivityManager =
(ConnectivityManager) context.getSystemService
( Context.CONNECTIVITY_SERVICE );- NetworkInfo activeNetInfo = connectivityManager.
getActiveNetworkInfo();- NetworkInfo mobNetInfo = connectivityManager.getNetworkInfo
( ConnectivityManager.TYPE_MOBILE );- if ( activeNetInfo != null )
- {
- Toast.makeText( context, "Active Network Type : " +
activeNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();- }
- if( mobNetInfo != null )
- {
- Toast.makeText( context, "Mobile Network Type : " +
mobNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();- }
- }
- }
- < !-- Needed to check when the network connection changes -->
