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 2.2.2 版，但遇到了一些问题，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

我不太确定原因，但一直在阅读有关多索引的信息，认为它是与此错误相关的组件之一。我还收到了下面的运行时间错误，我认为它也与问题有关：

感谢任何帮助或建议！

Answer 1

我想当你添加 firebase 时，你的应用程序有超过 64k 个方法，你需要遵循这个 link 关于 MultiDex

https://developer.android.com/studio/build/multidex.html

Answer 2

由于您没有 class com.troychuinard.fanpolls.FanPollsApplication，只需删除属性 name='.FanPollsApplication'。它将使用标准 android.app.Application 代替。
