android - 无法同时使用Google Analytics(分析)和Firebase依赖项

Question

共享我的gms依赖项:

implementation 'com.google.android.gms:play-services-location:15.0.1'
implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.google.android.gms:play-services-analytics:16.0.0'
implementation 'com.google.android.gms:play-services-auth:16.0.0'
implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-messaging:17.3.0'
implementation 'com.google.code.gson:gson:2.8.2'

建立应用程式时发生错误。分享错误。

如果删除“com.google.android.gms:play-services-analytics:16.0.0”依赖项，构建将成功。

如果我们删除了Firebase依赖项，构建也会成功。

implementation 'com.google.firebase:firebase-core:16.0.3'
   implementation 'com.google.firebase:firebase-messaging:17.3.0'

我无法同时使用Google Analytics(分析)和Firebase依赖项。如果您对此有任何想法请帮忙？

共享Google Service Gradle插件错误信息:

In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0.4]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

有关扩展的调试信息，请从命令行使用以下命令执行Gradle:
./gradlew --info:app:assembleDebug来查看到的依赖路径
神器。此错误消息来自google-services Gradle
插件，在以下位置报告问题
https://github.com/google/play-services-plugins并通过添加禁用
“googleServices {disableVersionCheck = false}”到您的build.gradle
文件。

Answer 1

play-services和firebase库的所有版本都必须为:

版本15.x或更低版本，它们都必须完全相同。

16.0及更高版本，它们可以是不同的版本。这需要Google服务Gradle插件版本3.3或更高版本。

无法在<= 15.x和> = 16.x之间混合使用。因此，您要么需要将Firebase降级到15.x，要么(更可能是)将Play Service升级到16.x。请参阅latest version of Play Services的文档。

另请参阅:
