Android Studio-AAPT：错误：文件无法使用PNG图像编译

如何解决Android Studio-AAPT：错误：文件无法使用PNG图像编译

我当时在Ubuntu Linux上工作，最近我撤出了我的项目并开始在Win10上工作。

从现在开始，我无法构建/运行我的应用程序。资源文件夹中的那些PNG文件一定存在问题。

这是尝试构建应用程序时的错误输出：

我不知道是什么原因造成的。我清理了缓存，删除并再次拉项目。我也找不到在线解决方案。

更新 发现Linux（Ubuntu）上的Android Studio工作正常，事实上，此错误仅发生在Windows的Android Studio上。

解决方法

如果某些文件已加密，则AAPT可能无法正常工作。请检查与编译错误相关的文件是否已加密。就您而言，这些是PNG文件。
