I think, If your database stored in application's internal storage /data/data/<package_name>/databases/ then when your application un-installed from device, all directories with your application package are removed from the device this cause your database removed.

To prevent put your database copy in application's /asset directory so whenever your application first time runt it copy the database from asset to internal storage path. And you can access it whenever application re-installed, also you can put your database in /sdcard but user can also delete it..

EDIT: Using your own SQLite database in Android applications and How to ship an Android application with a database?

Thanks...
