在将广告依赖项更新到最新版本后获得构建错误

Question

当我试图从Android Studio.运行我的应用程序时，我得到了这个构建错误

这只发生在我更新广告到最新版本的依赖关系。

:

implementation 'com.google.android.gms:play-services-ads:20.0.0'

:

implementation 'com.google.android.gms:play-services-ads:20.4.0'

如果我把它改回20.0.0，那么它工作得很好。我想问题出在最新版本的20.4.0上。

有谁能帮帮我吗?提前谢谢。

Answer 1

发布说明没有给出任何提示。

我现在使用20.3.0，它不会产生这个错误。

Answer 2

另一个Google拥有的库安装了一个冲突的com.google.android.gms:play-services-measurement-base版本。在我的例子中，它是Firebase Analytics。

重火力点分析

+--- com.google.firebase:firebase-analytics:18.0.0
|    +--- com.google.android.gms:play-services-measurement:18.0.0

Play Services Ads

+--- com.google.android.gms:play-services-ads:20.6.0
|    +--- com.google.android.gms:play-services-ads-lite:20.6.0
|    |    +--- com.google.android.gms:play-services-measurement-sdk-api:18.0.3
|    |    |    --- com.google.android.gms:play-services-measurement-base:18.0.3

将Firebase Analytics从18.0.0版本升级到20.1.2后，问题就解决了。

要确定在项目中哪个库是冲突的，输出依赖关系树并找到哪个库也安装了com.google.android.gms:play-services-measurement-base。然后将库升级到最新版本。
