二进制XML文件第27行:膨胀类androidx.appcompat.widget.ActionBarContainer

Question

我尝试了所有方法，但似乎无法解决此错误。我找到的所有解决方案都适用于androidx之前的代码。我想我添加了所有需要的依赖项，但它仍然不起作用。我还更新了我的android工作室和所有的依赖关系到他们的最新版本。如有任何帮助，我们将不胜感激。以下是我的Android Studio项目的代码片段：

Answer 1

请查看日志中的这一行：

原因：android.content.res.Resources$NotFoundException：Drawableandroid:color/primary_text_light，资源ID为0x1060003由以下原因引起：android.content.res.Resources$NotFoundException：来自可提取资源ID#0x1060003 的文件res/color/primary_text_light.xml

"primary_text_light.xml"似乎不存在或找不到

Answer 2

我遇到了同样的问题。所以我开始了一个新的空项目，根本没有我自己的代码。同样的错误！只有一个xml文件，它只有18行，但logcat在line#27上抱怨！

所以我只是升级了gradle，并在真实设备上成功加载了空应用程序。
