Android Packaging and User Data

When I package my Android app, how do I get my user data to be packaged along with it. For example, the db file in sqlite, I put it under user://. But after packaging it for android, I found that the file does not exist. What settings should I do, while packaging the app

One way would be to put it under res:// and copy it to user:// during initialization, when no such file is there yet.

I tried it out, manually selected the package and sent it to the phone for installation, and could read the database file. However, before I was using remote debug wifi, automatic installation, data file does not exist. Or am I setting something wrong where I need to look again
