看起来SecurityException会导致Firebase API initialization failure，然后会出现一些NullPointerExceptions。

我试图降级Performance Tools，这没用。 然后我将TargetSdkVersion从26设置为23，问题解除了。

将此添加到应用级别中的底部apply plugin: 'com.google.gms.google-services'＆＃39; 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'

The documentation表示Firebase效果监控取决于Google Play服务：

  

在开始之前，您需要在您的环境中设置一些内容：

     
      
  • 运行Android 4.0（Ice Cream Sandwich）或更新版本的设备，以及 Google Play服务15.2.0或更高版本
    •   
  • 来自Google Repository的Google Play服务SDK，可在Android SDK Manager中找到
    •   
  • 最新版本的Android Studio 2.2或更高版本
    •
