Android home screen widget no gets appWidgetId in Configuration Activity

I have a widget and I would like to add more than one of them to my screen, so I must control wich widget I'm configuring when I click on it in home screen with appWidgetId.

I'm following the documention in android.com, but I'm not getting the appWidgetId when I click on it in home screen.

Pieces of my code:

//MyWidgetClass

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {
    Log.i(TAG, CLASS_NAME + " onUpdate");
    for (int appWidgetId : appWidgetIds) {
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }
}

public static void updateAppWidget(Context context,
        AppWidgetManager appWidgetManager, int appWidgetId) {
    Log.d(TAG, CLASS_NAME + " updateAppWidget --- " + appWidgetId);
    if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {

        Intent settingsIntent = new Intent(context,
                Widget1x1SettingsActivity.class);
        settingsIntent
                .setAction(android.appwidget.AppWidgetManager.ACTION_APPWIDGET_CONFIGURE);
        //settingsIntent.putExtra("WIDGET_ID", appWidgetId);
        PendingIntent settingsPendingIntent = PendingIntent.getActivity(
                context, 0, settingsIntent, 0);

        RemoteViews remoteViews = null;

        int layout = R.layout.widget_1x1;
        remoteViews = new RemoteViews(context.getPackageName(), layout);
        // Do something ...

            remoteViews.setOnClickPendingIntent(R.id.widget,
                    settingsPendingIntent);

            ComponentName thisWidget = new ComponentName(context,
                    MyWidgetClass.class);
            appWidgetManager.updateAppWidget(thisWidget, remoteViews);

    }
}

//Settings class

@Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d(TAG, CLASS_NAME + " :: onCreate >>");
        super.onCreate(savedInstanceState);

        mContext = getApplicationContext();

        Intent intent = getIntent();
        Bundle extras = intent.getExtras();
        if (extras != null) {
            appWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID,
                    AppWidgetManager.INVALID_APPWIDGET_ID);
            //**//Here appWidgetId is 0 when I click on home screen widget**
        }
....
}

And when I click on ok button to finish the configuration activity:

AppWidgetManager appWidgetManager = AppWidgetManager
                    .getInstance(getApplicationContext());
            MyWidgetClass.updateAppWidget(getApplicationContext(),
                    appWidgetManager, appWidgetId);
            Intent resultValue = new Intent();
            resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
                    appWidgetId);
            Log.d(TA开发者_如何学JAVAG, CLASS_NAME + " Putting in RESULT resultValue extras: " + resultValue.getExtras() + " getInt(): " + resultValue.getExtras().getInt(AppWidgetManager.EXTRA_APPWIDGET_ID)); // it prints correct
            setResult(RESULT_OK, resultValue);
            finish();

I don't paste any xml file because I think they are ok.

Thanks in advance, SergiBC
