What is the difference between Sqlite and mysql is field of Android?

SQLite is standard on the Android platform so you won't have to add any external library.

Sqlite is a lite weight RDBMS that can be used both on desktop and mobile device. If you want your mobile app (either android or iOS) to store data locally to your device, SQLite is your best choice. If you want to either synchronize your data from mobile to central database server, you need to call a web service (written in either php or C#).
