我在Ubuntu linux上工作，最近我退出了我的项目，开始在Win10上工作。
从现在起，我无法构建/运行我的应用程序。resources文件夹中的那些PNG文件一定有问题。
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。我再次清理了缓存、删除和拉取项目。此外，我在网上找不到解决方案。
更新发现Linux(Ubuntu(上的Android Studio运行良好，事实上，此错误仅发生在Windows的Android Studio上。。
我遇到了类似的问题，根本原因是JPEG文件的扩展名是PNG。一旦我修复了文件扩展名，AAPT很高兴。
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已加密。在您的情况下，这些是PNG文件。
在我的案例中，我试图使用从whatsapp下载的一些png图像，这些图像经过了加密。
要修复它，请执行以下步骤：
1-开放式油漆2-打开您的图像3保存
你已经准备好出发了！
如果是expo应用程序，请删除您刚才添加的png资产。你可以将它们重命名为jpg，这将适用于
我也有同样的错误。尝试了一切，包括拔出我自己的耳朵，但都没用。然后有人提到运行Android Studio作为admin可以解决这个问题。。。因此，它与write access问题有关。答对 了试试这个：
In windows go to Ransomware protection and disable it!
然后尝试再次构建。如果有效，则使用Allow an app through Controlled folder access赋予gradle访问权限。然后再次启用勒索软件保护。
在Windows中，尽量将您的项目保存在与Windows不同的驱动器(C驱动器(中。您可以使用D驱动器并尝试保持路径较短(例如D:\Projects\XyzProject(。这可能会解决您的问题。
我面临同样的问题，并已解决。此错误是由于windows安全性，请选择导致问题的文件属性并取消阻止。
这个问题不过是图像文件扩展名的问题。我的图像是jpeg格式的，但我把它保存在我的可绘制文件夹中作为png格式。这就是为什么这场冲突是由android引发的。
我只是将我的图像转换为png版本，并在我的android项目中实现，并删除了旧的jpg图像。然后android正常工作。
