檢查意圖互聯網連接有安卓系統嗎？Intent ACTION_XXX當互聯網連接可用時通知我？我想實例化一個BroadcastReceiver當用戶啟用Internet連接(通過wifi、GSM等)時，通知我的應用程序。有人能幫我嗎？

public class NetworkStateReceiver extends BroadcastReceiver {
private static final String TAG = "NetworkStateReceiver";
@Override
public void onReceive(final Context context, final Intent intent) {
Log.d(TAG, "Network connectivity change");
if (intent.getExtras() != null) {
final ConnectivityManager connectivityManager = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
final NetworkInfo ni = connectivityManager.getActiveNetworkInfo();
if (ni != null && ni.isConnectedOrConnecting()) {
Log.i(TAG, "Network " + ni.getTypeName() + " connected");
} else if (intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, Boolean.FALSE)) {
Log.d(TAG, "There's no network connectivity");
}
}
