java - Android Studio应用程序(Java)中的模块中的重复类androidx.lifecycle.DefaultLifecycleObserver

Question

我在网上找了半天怎么解决这个错误没有找到。我试着按照写的here进行搜索，但我没有找到任何东西，可能是因为我不明白如何使用它。这是什么错误？如何解决？请帮帮我。附言我可以添加任何必要的文件或其他信息。

在模块生命周期-common-2.4.0.jar (androidx.lifecycle:lifecycle-common:2.4.0) 和生命周期-common-java8-2.3.0.jar 中发现重复的类 androidx.lifecycle.DefaultLifecycleObserver (androidx.lifecycle:lifecycle-common-java8:2.3.0)

Lifecycle 在单一版本约束下运行 - 这意味着您在应用中使用的每个 Lifecycle Artifact 都应该具有完全相同的版本号(不幸的是，Gradle 不会为您强制执行此操作)。

您的错误表明您的依赖项之一是对 androidx.lifecycle:lifecycle-common-java8:2.3.0 的依赖项，它与 2.4.0 不匹配 您正在使用的其他生命周期依赖项的版本。

因此，要解决您的问题，请添加对 lifecycle-common-java8 的 2.4.0 版本的依赖项:

implementation 'androidx.lifecycle:lifecycle-common-java8:2.4.0'
