当我尝试验证.apk(andriod 应用程序(是否已签名时，我看到以下错误。
我不确定此错误到底是什么意思？
这是否会引起任何安全问题？

谢谢
APK 的签名保证，如果文件在签名后在 APK 中发生更改，则无法将其安装在 Android 设备上(签名将失效(。
APK 的签名存储在 APK 的 META-INF 目录中，这意味着如果其他一些文件存储在 META-INF 目录中，则它们不会被签名覆盖。您看到的警告显示 APK 中的一些文件位于 META-INF 目录中，不受签名保护。
实际上，这些文件并不重要，它们大多是你所依赖的库的版本(只有版本号，而不是已经在 dex 代码中编译的那些库的实际代码(，所以即使有人修改了这些文件，也不会对你的应用程序产生任何影响。这就是为什么它只是一个警告：APK中的那些文件可以被其他人修改，同时仍然假装APK是由你签名的，但这些文件并不重要。
这在APK中很常见，所以我不会担心。
