问题描述

我试图发展用于备份文件的应用程序。我需要提取安装的应用程序的APK文件，例如天文管理者做的。

I am trying to develop a application for backing up the files. I need to extract the APK files of installed applications like the Astro manager does.

如果有谁知道如何提取，请给我的解决方案。

推荐答案

它们存储在 /数据/应用/ ，但除非你的手机是植根你不会看到任何那里。

They are stored in /data/app/ but unless your phone is rooted you won't see anything there.

系统的apk都存储在 /系统/应用程序

System apk's are stored at /system/app

获取准确的apk路径的一种更好的方式：

A better way of getting the exact apk path :

PackageManager  pm = getPackageManager();
List<PackageInfo> pkginfolist = pm.getInstalledPackages(PackageManager.GET_ACTIVITIES);
List<ApplicationInfo> appinfoList = pm.getInstalledApplications(0);
for (int x = 0; x < pkginfolist .size(); x++) {             
  PackageInfo pkginfo = pkginfolist.get(x);
  pkg_path[x] = appinfoList.get(x).publicSourceDir;  
}
