获取安装的应用程序APK [英] Get APK of installed app
问题描述
我要寻找一种可能性来提取的安装Android应用程序的APK文件，而无需root权限。直到5分钟前，我认为这是不可能的，因为所有的应用程序的apk位于/数据/应用程序（非系统应用程序）和访问这个文件夹就是可能的root权限。
I am looking for a possibility to extract the apk files of an installed android app WITHOUT root permission. Until 5 min ago I thought that this is not possible, since all app apks are located in /data/app (non-system-apps) and accessing this folder is just possible with root permission.
后来我发现，在谷歌Play商店的virus.total Android应用程序（https://play.google.com/store/apps/details?id=com.virustotal），他们似乎有机会获得的apk连在非root权限的设备。
Then I found the virus.total Android app in the google play store (https://play.google.com/store/apps/details?id=com.virustotal) and they seem to have access to the apks even on non rooted devices.
有人可以告诉我这怎么可能？是不是有备份软件的备份，而不根的apk ???
Can someone tell me how this is possible ? Aren't there backup apps which backup the apks without root ???
非常感谢你。
推荐答案
访问/数据/应用程序可能没有root权限;在该目录的权限是rwxrwx - X。执行权限上的目录意味着你可以访问它，但是没有读权限意味着你无法获得其内容的列表 - 因此，为了获得它，你必须知道你将要访问的文件的名称。 Android的包管理器会告诉你，一个给定的包中存储的apk的名字。
Accessing /data/app is possible without root permission; the permissions on that directory are rwxrwx--x. Execute permission on a directory means you can access it, however lack of read permission means you cannot obtain a listing of its contents -- so in order to access it you must know the name of the file that you will be accessing. Android's package manager will tell you the name of the stored apk for a given package.
要在命令行中执行此操作，使用亚行外壳时列表包来获取安装包的列表，找到所需的包。
To do this from the command line, use adb shell pm list packages to get the list of installed packages and find the desired package.
通过包名，就可以得到实际的文件名，并使用APK的位置亚行外壳时路径的包名。
With the package name, we can get the actual file name and location of the APK using adb shell pm path your-package-name.
和知道完整的目录，我们可以使用亚行拉满/目录/终于拉亚行/ the.apk
And knowing the full directory, we can finally pull the adb using adb pull full/directory/of/the.apk
