Question

我将Firebase用于少数服务（分析，firestore，崩溃...），并且一切正常。

但是，每当我在API 28设备上启动我的应用程序时，都会出现以下错误：

java.lang.RuntimeException：无法获取提供程序 com.google.firebase.provider.FirebaseInitProvider： java.lang.ClassNotFoundException：找不到类路径上的“ com.google.firebase.provider.FirebaseInitProvider”： DexPathList [[zip文件“ / data / app /[...]

这发生在我之前的许多人身上（可以看到here，here，here或here），但是没有人描述这种API选择性行为（通常甚至相反，它可以在新的API上运行，而在旧的API上崩溃）。

我可以在一些设备上对此进行测试，然后得到以下结果：

在API 22、23和26（genymotion仿真器）上，它像一个魅力一样工作
它在API 28（仿真器和实际的One Plus 6）上崩溃了

我使用com.getkeepsafe.dexcount插件检查我是否真的不需要multidex。输出如下：

Methods remaining in app-dev-debug.apk: 15744
Fields remaining in app-dev-debug.apk:  33647
Classes remaining in app-dev-debug.apk:  59277

这是我的app模块build.gradle（但随时询问更多代码或其他代码）：

    plugin 'com.android.application'
    plugin 'io.fabric'
    plugin 'realm-android'
    plugin 'com.google.gms.google-services'

}

我尝试了其他问题的答案，例如添加multidex（即使我显然不需要它），但这没有帮助。也不清理我的项目或重建。

API 28可能是什么问题？

仅在API28中用于FirebaseInitProvider的ClassNotFoundException
