问题描述

我从互联网上下载了 Myfiles.apk 并尝试将其安装到我的 Android 模拟器中.

I downloaded Myfiles.apk from the internet and I'm trying to install it to my Android emulator.

在通过命令提示符安装 Myfiles.apk 文件时，我收到此错误.

推荐答案

这个 网站帮助我正确签署未签名的apk.但是，对于最后一个过程，即对于 jarsigner，需要使用以下命令

This site helped me a lot to properly sign the unsigned apk. But,for the last process i.e. for jarsigner,following command need to be used

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore    my_application.apk alias_name.

如果您遇到任何zipexception 错误.所以总的来说，使用以下程序

Further do look upon this unable to sign zipexception if you encounter with any zipexception error . So overall,use following procedure

1. keytool -genkey -v -keystore debug.keystore -alias android -keyalg RSA -keysize 2048 -validity 20000
2. jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore yourapkalign.apk alias_name
3. zipalign -v 4 yourapk.apk yourapkalign.apk

现在，您可以成功安装apk文件了.

Now,you can successfully install the apk file.
