<menu xmlns:android="http://schemas.android.com/apk/res/android" >

        android:orderInCategory="100"
        android:showAsAction="never"

            final Intent intent = new Intent(this, NetworkSettingActivity.class);
            startActivity(intent);
            break;
        case R.id.action_settings:
            final Intent intent = new Intent(this, SettingsActivity.class);
            startActivity(intent);
            break;
        default:
            Log.e(TAG, "onOptionsItemSelected: invalid menuitem id " + String.valueOf(item.getItemId()));
