android - angular2-seed-advanced 中的 Telerik-UI 侧抽屉(Android 设备)

Question

我试图让它工作，但它只会给我以下错误。我为 nativescript-groceries 应用做了几乎相同的事情，但是 angular2-seed-advanced 的架构有些不同，似乎是 nativescript 和种子项目以及 telerik- 之间某处的依赖注入(inject)问题用户界面。

感谢任何帮助:

这是我的改动

好的，让它工作并想分享它，因为它不是很简单，也不是特别有据可查...

随着 nativescript-telerik-ui 1.4.1 的发布和 Angular 2.0.0 的最终发布，这实际上非常容易。
