似乎是 SecurityException 导致了 Firebase API 初始化失败，然后出现了一些 NullPointerExceptions。

我试过降级性能工具，没用。然后我将 TargetSdkVersion 从 26 设置为 23，问题消失了。

将此添加到底部 apply plugin: 'com.google.gms.google-services' in app level '并使用 this最新的 firebase 依赖项，如果您使用的是 android studio 3.x 版本，请使用 'com.google.firebase:firebase-plugins:1.1.5'
