在 Android Studio 应用 (Java) 的模块中重复 class androidx.lifecycle.DefaultLifecycleObserver

Question

我在网上搜索了很长时间如何解决这个错误，但没有找到it.I 尝试按照here 中所写的进行搜索，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？请帮助我。 P.S。我可以添加任何必要的文件或附加信息。

Duplicate class androidx.lifecycle.DefaultLifecycleObserver found in modules lifecycle-common-2.4.0.jar (androidx.lifecycle:lifecycle-common:2.4.0) and lifecycle-common-java8-2.3.0.jar (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 工件都应该具有完全相同的版本号（不幸的是，这不是 Gradle 会为您强制执行的） .

您的错误指出您的一个依赖项正在引入对 androidx.lifecycle:lifecycle-common-java8:2.3.0 的依赖项，这与您正在使用的其他生命周期依赖项的 2.4.0 版本不匹配。

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

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