Firestore崩溃具有新依赖项的应用程序

Question

昨天我用17.1.1用4.1.0和Google Services更新了Firestore的依赖项。现在，在启动应用程序时，它崩溃了。

注意：

如果我将Google服务更改为4.0.2，则Firestore会正确初始化并且应用程序会按预期运行。

classpath 'com.google.gms:google-services:4.0.2'

更新：

改为4.2.0的作品。

Answer 1

没有必要使用FirebaseApp.initializeApp(context)。仅使用依赖关系就足够了。因此，如果您执行标准集成，则不应该手动调用它，因为它将通过ContentProvider自动调用，该how to initialize Firebase on Android将在任何其他Activity或Service之前初始化。你可以阅读Doug关于alpha13的帖子。

您的代码中的问题是您的项目使用classpath 'com.android.tools.build:gradle:3.3.0-alpha13' 版本作为您的gradle。要解决此问题，请更改以下代码行：

classpath 'com.android.tools.build:gradle:3.2.0'

根据qazxswpoi，这是play-services插件4.1.0中确认的错误。答案是使用早期版本，例如4.0.2。

编辑：版本4.2.0已发布，其中修复了错误。
