在发布修复程序之前有任何解决方法？

Answer 1

使用了gradlew :app:dependencies，发现某些依赖项没有使用最新版本。

手动添加以下依赖项以覆盖加载的版本可以解决该问题。

implementation 'com.google.android.gms:play-services-measurement-sdk-api:16.0.3'
implementation 'com.google.android.gms:play-services-basement:16.1.0'

Answer 2

一旦遇到此问题，请尝试将Google Play服务版本更新为最新版本，并更新您正在使用的所有Firebase库。从Android Studio 3.2.1开始，以下是最新的内容：

 dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.0.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

Answer 3

这是简单的解决方案，

Google已解决此问题，您需要做的就是将ads gradle版本更新为17.1.1，这将解决firebase-core：16.0.5的问题，添加以下几行即可解决该问题

implementation 'com.google.firebase:firebase-ads:17.1.1'
implementation 'com.google.android.gms:play-services-ads:17.1.1'
implementation 'com.google.firebase:firebase-core:16.0.5'

使用firebase-analytics时重复的jar条目：16.0.5
