我使用的是 android studio 3.3，一切正常。但是今天更新到 3.4 后我得到了这些错误。看来问题源于 androidX 依赖项。它也发生在我的两个依赖于 androidX 的不同项目中。

我尝试了以下方法:

1.清理并重建我的项目

2.使缓存失效并重启。

我该如何解决

最佳答案

我通过在 gradle-wrapper.properties

来自

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

回到

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip

并且还从 build.gradle 中恢复 gradle 依赖性

classpath 'com.android.tools.build:gradle:3.4.0'

回到

classpath 'com.android.tools.build:gradle:3.3.2'

现在我的项目很好。
