问题描述
昨天,我用 17.1.1
更新了Firestore的依赖关系,并用 4.1.0
更新了Google Services的依赖关系.现在,在启动应用程序时,它会崩溃.
Yesterday I updated the dependencies of Firestore with 17.1.1
and Google Services with 4.1.0
. Now while launching the app it crashes.
注意:
如果我将Google Services更改为 4.0.2
,则Firestore会正确初始化,并且该应用程序将按预期运行.
If I change Google Services to 4.0.2
, the Firestore initializes properly and the app works as expected.
classpath 'com.google.gms:google-services:4.0.2'
更新:
更改为 4.2.0
可行.

推荐答案
无需使用 FirebaseApp.initializeApp(context)
.仅使用依赖项就足够了.因此,如果您执行标准集成,则无需手动调用它,因为它将通过 ContentProvider
自动启动,该启动将在任何其他Activity或Service之前初始化.您可以在如何初始化中阅读道格的帖子Android上的Firebase .
There is no need to use FirebaseApp.initializeApp(context)
. Using only the dependencies is enough. So you shouldn't ever have to call it manually if you performed the standard integration, as it will be invoked automatically a startup via a ContentProvider
that will initialize before any other Activity or Service. You can read Doug's post regarding on how to initialize Firebase on Android.
您的代码中的问题是您的项目正在使用gradle的 alpha13
版本.要解决此问题,请更改以下代码行:
The problem in your code is that your are using for your project the alpha13
version for your gradle. To solve this, please change the following line of code:
classpath 'com.android.tools.build:gradle:3.3.0-alpha13'
到
classpath 'com.android.tools.build:gradle:3.2.0'
将解决此问题.
