As a sibling comment says, if you are on Android and have root access, it is very easy.

Just have a look at /data/data/appname/.

For example, this is what I copy to make backups of my contacts on my Android phone:

> # pwd

> /data/data/com.android.providers.contacts/databases

>> # ls -1

> calllog.db

> contacts2.db

> profile.db

This is a simple way for moving data around, restoring applications, performing backups, editing your data (if you know your way inside the app).

Beware of the selinux labels if you are moving files across different devices, as recent android version now run with selinux in enforcing mode.

Just be sure to adjust them (useful commands if you need a reference: ls -lZ, chcon, semanage).
