android – Apk Metainfo警告

当我尝试验证时,如果.apk(andriod应用程序)已签名,我会看到以下错误.

我不确定这个错误究竟意味着什么？

这会引起任何安全问题吗？

谢谢

APK的签名保证如果文件在签名后在APK中更改,则无法在Android设备上安装(签名将无效).

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,则签名不会覆盖它们.您看到的警告会显示APK中某些文件,这些文件位于META-INF目录中,不受签名保护.

在实践中,这些文件并不重要,它们主要是您所依赖的库的版本,因此即使有人修改了这些文件,也不会对您的应用产生任何影响.这就是为什么它只是一个警告：你的APK中的那些文件可以由其他人修改,同时仍假装APK由你签名,但这些文件并不重要.

这在APK中很常见,所以我不担心.
