ActiveAndroid
ActiveAndroid is a persistence framework for managing local SQLite databases on Android. It provides an active record object-relational mapping system that binds database tables to classes, allowing for data persistence and retrieval without writing manual SQL.
The project distinguishes itself through a dedicated schema migration tool that updates database structures using versioned scripts loaded from application assets. It also includes a framework for sharing database content between different Android applications via a standard URI-based content provider interface.
The library covers broad capability areas including object-relational mapping for managing table relationships and custom data types, bulk transaction processing for data ingestion, and automated database initialization from pre-populated asset files. It further provides utilities for programmatic querying and column indexing to manage data lookup and retrieval.
Features
- Active-Record ORMs - Provides an Active Record ORM that binds data access logic directly to model objects.
- Android SQLite Management - Provides a comprehensive persistence framework for managing SQLite databases within the Android ecosystem.
- Schema Migration Scripts - Uses ordered SQL scripts from assets to incrementally update database structures across application versions.
- Database Schema Migrations - Automates the application of versioned updates to database schemas to maintain structural compatibility.
- Object-Relational Mapping Associations - Manages relationships and foreign key associations between database entities at the ORM level.
- Programmatic Query APIs - Retrieves objects from the database using a programmatic API to filter and fetch records.
- Schema Migration Tools - Ships a management tool for updating database structures using versioned scripts loaded from assets.
- Class-to-Table Mappings - Maps classes to tables using annotations to manage primitive data types and primary keys.
- Object Relational Mappings - Provides an object-relational mapping system to bind Android classes to SQLite tables using annotations.
- Content Providers - Implements standardized Android Content Providers to share database content with other applications.
- Inter-App Data Sharing - Exports database records to other Android applications via system-standard content providers.
- URI-Based Content Provisioning - Exposes database records to external applications using a standard provider interface and URI-based access patterns.
- Schema Mappings - Maps application objects to database table columns using metadata annotations.
- Database Schema Migrations - Implements a dedicated tool for updating database schemas through sequential, versioned SQL scripts.
- Custom Type Serializers - Implements serialization and deserialization logic to map complex Java objects to primitive database types.
- Data Type Mappings - Translates application-level complex data types into native database column formats.

- Database Initializations - Provides mechanisms for initializing the database using pre-populated files from application assets.
- Database Schema Initializations - Provides a mechanism to initialize the database structure and seed it with data from application assets.
- Database Setup - Automates the configuration and initialization of the database layer during application startup.
- Bulk ORM Operations - Provides high-speed bulk insert and update operations for records using batch processing.
- Record Deletion - Provides methods for removing specific database records based on object instances or query criteria.
- Bulk Record Insertions - Supports bulk record insertion by wrapping multiple save operations in a single atomic transaction.
