But, i can't see the installed application on my real device. Where it is stored. I can see the default application from here /system/app But i can't see installed application whatever i downloaded and my own application. Anyone guide me?

推荐答案

在模拟器，你有root权限。

On the emulator, you have root access.

在你的手机，你没有root访问权限（除非你根它）。而且每个应用程序都有自己的私有文件夹与自己的Linux用户ID，这样一个应用程序可以不看到另一个应用程序的文件夹。这可是Android安全模型的一个方面。还有更多。

On your phone, you do not have root access (unless you root it). And each application gets its own private folder with its own linux userid, so that one application can not look into the folder of another application. This is but only one aspect of the Android security model. There are many more.

您寻找在这些文件夹什么特别？如果是这样，也有变通方法。例如，如果你想看看你的sqlite.db文件，一个解决办法是让自己的应用程序（因为它有这样做的权限）编程读取数据库文件和重组它在SD卡上（每次要手动检查）。

Are you looking for anything in particular in those folders? If so, there are workarounds. For instance, if you're trying to look at your sqlite.db file, one workaround is to have your own application (since it has the permission to do so) programmatically read the database file and reconstitute it on the SD card (every time you want to manually check it).
