读取 PNG 签名失败：文件不以 PNG 签名开头

Question

Gradle 构建失败并出现此错误：

 Error:C:\Users\Roman\.gradle\caches\transforms-1\files-1.1\appcompat-v7-26.0.2.aar\bab547c3f1b8061ef9426f524a823a15\res\drawable-xhdpi-v4\abc_btn_switch_to_on_mtrl_00001.9.png failed to read PNG signature: file does not start with PNG signature

我试图解决这个问题的一些基本事情：

1. 使缓存无效/重新启动
2. 删除 gradle 文件夹

打开 [Root_project]/app/build.gradle 并添加以下行。

 release {
          ...

            crunchPngs false // or true

            lintOptions {
                checkReleaseBuilds false
                abortOnError false
            }

          ...
}
