You have many options:

1) SQLiteOpenHeleper:

You can store data into SQLite database with SQLiteOpenHelper class.

for a simple implementation watch this link : Android SQLite Example

2) Room Library: (Recommended)

This is a great library written by google that provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.

for a simple implemantation watch this links: A Beginner’s Guide to the Room Persistence Library Room Persistence Library

3) Shared Prefrences: If you have a simple data you can store it via Shared Prefrences. it is not a database though. Shared Preferences allow you to save and retrieve data in the form of key,value pair inside xml files in device data folder.

for a simple implementation watch this: How to use SharedPreferences in Android to store, fetch and edit values

4) Realm: Realm is a mobile database and a replacement for SQLite. Realm is not using SQLite as it’s engine. Instead it has own C++ core and aims to provide a mobile-first alternative to SQLite.

You can learn it with this link: How to use Realm for Android like a champ, and how to tell if you’re doing it wrong

5) ETC There is some other types like File (read/write) and greenDao. You can learn them by just simple googling :)
