android - 为什么我的应用程序在使用 Admob 和 Firebase 时会崩溃？

Question

我在 Google Play 上发布了一个应用。然后我将它链接到 Admob 并且该应用程序运行，向我展示了 admob 的横幅。有时，在启动时，它会崩溃，有时不会。我查看了 Android Studio Logcat，这是错误。有人可以帮助我吗？

Android 9.0 最终默认删除了旧 Apache HTTP 库的所有痕迹。然而，似乎有些图书馆需要它。您需要将其添加到 <application> 内的 list 中元素:

<uses-library
    android:name="org.apache.http.legacy"
    android:required="false"/>
