Android Studio 在更新到 2.2.2 时无法识别应用程序名称

Question

我最近将 Android Studio 更新到了 2.2.2 版，并且遇到了一些问题，其中包括清单中不再识别我的应用程序名称。我还根据位于 here 的文档迁移到了新的 Firebase SDK：

我不完全确定原因，但一直在阅读有关 multidexing 作为与此错误相关的组件之一的信息。我还在下面收到了一个运行时错误，我认为这也与该问题有关：

感谢任何帮助或建议！

Answer 1

由于您没有类com.troychuinard.fanpolls.FanPollsApplication，因此只需删除属性name='.FanPollsApplication'。它将改用标准的android.app.Application。

Answer 2

我认为当你添加 firebase 时，你的应用程序有超过 64k 的方法，你需要点击这个关于 MultiDex 的链接
