Android Studio - AAPT：错误：文件无法使用 PNG 图像进行编译

Question

我当时在 Ubuntu linux 上工作，最近我撤回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 文件肯定有问题。

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，删除并再次拉取项目。我也无法在网上找到解决方案。

更新 发现Linux(Ubuntu)上的Android Studio工作得很好，事实上这个错误只发生在Windows的Android Studio上。

Answer 1

我遇到了与此类似的问题，根本原因是 JPEG 文件以 PNG 文件扩展名命名。一旦我修复了文件扩展名 AAPT 就很高兴。

Answer 2

如果某些文件已加密，AAPT 可能无法正常工作。请检查与编译错误相关的文件是否被加密。在您的情况下，这些是 PNG 文件。
