I read that during .apk installation process a new user is created and with this new user rights, the Applications directory(.apk is extracted here) in the internal storage is created (in /data/app , not very sure). I can’t find any Application directory in /data/app , even /system/app also contain .apk not Application directories . Can someone explain where I can find Application directories ??

Also what are the things happens during installation process (I am interested in knowing if some specific files are copied to specific location).

    You read wrong 🙂 APKs are not extracted on the file system, just decompressed in memory. So you will only find APK files in /data/app, /system/app, etc. The whole process is version dependent (for example Jelly Bean adds forward locking/encryption). You need to read the Android source to get the actual details. Start with PackageManagerService.java.
