I’m programming a game with my own engine. I want to create a store in my game. It will be adding some new features for game with coins.
How can I store game data like coin quantity,new characters(bought or not bought)? SQlite or any other way to do this?How do professionals do it?
Please look at the Android Dev Guide for the data storage topic.
Also check out SQLite which is a sub section of the guide posted above.
Info on how to encrypt data in a SQLite Database:
Android SQLCipher
PBKDF2
Hope this helps!
