在应用程序启动器（抽屉），该应用程序应该更新，但快捷方式不会被更新，直到主屏幕的一次刷新。没有什么可以做，不幸的是，但在主屏幕确实在一段时间自动刷新一次，因此，新的图标将最终自动替换旧的图标。

The app in the app launcher (drawer) should be updated, but the shortcuts won't be updated until the next refresh of the homescreen. There isn't much you can do that unfortunately, but the homescreen does refresh itself once in a while, so the new icon will eventually replace the old icon automatically.
