问题描述

在v21之前的所有版本(即16-19)上，由于以下错误，我的应用在启动时崩溃:

On all versions before v21 (i.e. 16-19), my app crashes on start because of the following error:

在Android 5及更高版本上，我的应用可以正常运行.

On Android 5 and up, my app works without any issues.

我的目标是SDK版本27，最低版本是14.是的，我还启用了Multidex支持.我已经看到了一些答案，但是它们与我的问题无关，因为我已经启用了多年.目前，我还在使用最新的Firebase服务11.8.0.

I am targeting SDK version 27 and my minimum version is 14. Yes, I have also enabled Multidex support. I have seen some answers about that, but they aren't relevant to my issue as I have this enabled for years already. Currently I am also using Firebase services 11.8.0, the latest.

推荐答案

已修复！

尽管我已在Gradle中导入并启用了multidex，但我不得不更改Application类以扩展 MultidexApplication 而不是 Application .

Although I had multidex imported and enabled in Gradle, I had to change my Application class to extend MultidexApplication instead of Application.
