android - 如何解决错误 : In project 'app' a resolved Google Play services library dependency

Question

在我将 com.google.android.gms:play-services-ads 依赖项从 17.2.0 更新到 18.0.0 之后，我出现以下错误:

ERROR: In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[16.5.
0]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

Dependency failing: com.google.android.gms:play-services-measurement-api:16.5.0 -> com.google.android.gms:play-services-
measurement-sdk-api@[16.5.0], but play-services-measurement-sdk-api version was 17.0.0.

The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
ifact with the issue.
-- Project 'app' depends onto com.google.android.gms:play-services-ads@18.0.0
-- Project 'app' depends onto com.google.firebase:firebase-analytics@{strictly 16.5.0}
-- Project 'app' depends onto com.google.android.gms:play-services-ads@{strictly 18.0.0}
-- Project 'app' depends onto com.google.android.gms:play-services-measurement-api@{strictly 16.5.0}
-- Project 'app' depends onto com.google.android.gms:play-services-measurement-sdk@{strictly 16.5.0}
-- Project 'app' depends onto com.google.android.gms:play-services-measurement-sdk-api@{strictly 17.0.0}
-- Project 'app' depends onto com.google.firebase:firebase-core@16.0.9
-- Project 'app' depends onto com.google.android.gms:play-services-ads-lite@{strictly 18.0.0}
-- Project 'app' depends onto com.google.firebase:firebase-core@{strictly 16.0.9}

For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b
uild.gradle file.

Answer 1

您的 Gradle 文件中的依赖项似乎存在版本冲突。

请查看Release Notes June 17, 2019找到它们。

Artifacts released on maven.google.com
com.google.android.gms:play-services-ads:18.0.0
com.google.firebase:firebase-core:17.0.0
com.google.firebase:firebase-messaging:19.0.0

等等

在你的代码中，firebase 相关的似乎是基于 May 07, 2019 的发布。

implementation 'com.google.android.gms:play-services-ads:18.0.0'
implementation 'com.google.firebase:firebase-core:16.0.9' // old
implementation 'com.google.firebase:firebase-messaging:18.0.0' // old
