通过Java代码获取android设备上已安装的应用程序的.apk文件

Question

是否可以使用Java代码为已安装在android设备上的应用程序生成.apk文件？

Answer 1

All the android apk are stored in the following path:

/data/app

The permissions of this dir is drwxrwx--x

The permission if the files(apk's) inside this folder are -rw-r--r--

Since there is read permission for others , so you will be able to read the files if you know the names of the apk's. You can do that by the means of simple java File IO operations.
