Question

大家好，我正在尝试将Firebase添加到我的应用中，但是在运行时停止在模拟器上工作

我的日志：

首先尝试使用以google-play-services为后盾的模拟器，然后选中this

还如崩溃所解释的那样，尝试致电

FirebaseApp.initializeApp(Context)

在活动中使用Firebase实例之前，您可以在Application类onCreate方法中执行以下操作：

FirebaseApp.initializeApp(getBaseContext())

并确保您正确应用最新 google-play-services插件

在Android Studio中运行时，Android应用程序无法在模拟器上运行
