面对我自己，在评论中看到过几次类似的问题-即使安装了“最新”谷歌播放服务和谷歌存储库仍然有同样的问题。

问题是，它们可能是当前Android SDK工具版本的最新版本，但不是应用构建所需的最新版本。

In such case make sure to install latest version of Android SDK Tools first, and probably Android SDK Platform-tools (both under Tools branch). Also please note you may need to go through this several times if you haven't updated for a long time (i.e. install latest Android SDK Tools and Android SDK Platform-tools, then restart Android SDK Manager, then repeat), since the updates seem to be going through some critical mandatory milestones and you cannot install the very latest if you currently have the revision which is pretty "old".

错误:(30,13)Failed to resolve: com.google.firebase:firebase-auth:9.6.1

如果你遇到这个错误，并且你使用的是Android studio 2.2，其中集成了firebase组件，默认的库版本为9.6.0，你正在添加9.6.1等最新的依赖项。您可能需要将com.google.firebase:firebase-auth:9.6.1降级为com.google.firebase:firebase-auth:9.6.0

或者检查您预先安装的firebase的库版本，并确保它与您试图添加或添加到项目中的新库版本相同。

我尝试了所有的方法，但没有一种对我有效。更改gradle版本对我来说很有效。

我在gradle-wrapper.properties中更改了以下内容

from

distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

to

distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip

2022年10月更新

com.google。firebase-core已于2022年10月弃用。使用firebase-analytics或firebase- analysis -ktx而不是firebase-core。

firebase-core库已弃用，不会有其他版本 被释放。该SDK包括谷歌Analytics的Firebase SDK。 现在，要使用谷歌Analytics或推荐添加的产品 谷歌Analytics，你需要显式地声明Analytics 依赖:com.google。重火力点:firebase-analytics或 com.google.firebase: firebase-analytics-ktx。
