apk file parsing

Each and every android application is bundled as an apk file. When an apk file is installed different entites (files) of the application are stored in different parts of the system. For example i have found that real player stores its files in the following places of the android file system /data/data/com.real.RealPlayer /data/app/com.real.RealPlayer-1.apk /data/dalvik-cache/data@app@com.real.RealPlayer-1.apk@classes.dex /data/system/packages.list /data/system/packages.xml /data/data/com.sec.android.app.twlauncher/databases/launcher.db

How can i do this for every installed application on my phone/emulator?? Is it the right way to parse apk file 开发者_Go百科and find the places where all the parts of the app are stored?? Any ideas?

On normal non-rooted phones an application can see only its own files, due to security restrictions.
