Upgrade Database

Sometime as developer you want add new word to database SQLite but do not want to replace user word that already created, so in version 5.0 we split database into two Db file :

database.sqlite  ---> Original database      ( Upgradeable )  
database_user.sqlite  ---> User database     ( Non upgradeable )

To upgrade original database you need to increment value db_version at file string.xml

<integer name="db_version">1</integer>

ex : 1, 2, 3 ... n When you increment db_version this current original database at user device will be replaced with new database from app\src\main\assets.
