title: RemoteViews setViewVisibility on Android Widget
body: <p>In my AppWidgetProvider, I do following:</p>
  
  <pre><code>@Override
  public void onReceive(Context ctx, Intent intent) {
      final String action = intent.getAction();
      if (action.equals(NEXTPAGE_ACTION)) {
          AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(ctx);
          RemoteViews rv = new RemoteViews(ctx.getPackageName(), R.layout.widget_layout);
          rv.setViewVisibility(R.id.page1, View.GONE);
          rv.setViewVisibility(R.id.page2, View.VISIBLE);
      final int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
      appWidgetManager.updateAppWidget(appWidgetId, rv);
      }
  }
  </code></pre>
  
  <p>Although I'm updating the layout via updateAppWidget, the change is not really reflected on the UI. What could be possibly going wrong? Thanks much!</p>
