Android provides a set of APIs that allow developers to interact with SQLite databases. These APIs are included in the Android SDK and can be used to create, read, update, and delete data from SQLite databases.
Some of the key features of Android SQLite include:
1. Lightweight: SQLite is a lightweight database that doesn't require much memory or resources to function. This makes it ideal for use on mobile devices.
2. Transactional: Android SQLite supports transactions, which means that any changes made to the database are either fully committed or fully rolled back.
3. Easy to use: The Android SQLite APIs are easy to use and can be accessed using simple SQL commands.
4. Open-source: Android SQLite is an open-source project, which means that developers can contribute to its development and improve its functionality.

Android SQLite is a built-in database engine that is used to store and manage data in Android applications. SQLite is a lightweight and fast database engine that stores data in a relational database management system (RDBMS) format. It is a part of the Android operating system and can be accessed using the Android SDK.
SQLite databases can be created and managed using SQL commands, and data can be inserted, updated, and deleted using SQL queries. Android SQLite provides a set of classes and methods that can be used to interact with the database, such as SQLiteOpenHelper, SQLiteDatabase, and Cursor.
Developers can use Android SQLite to store various types of data in their applications, such as user preferences, settings, and local data. It is also commonly used to implement offline caching and data synchronization in mobile applications.
