Features

• Android Libraries - An official collection of libraries that provide backward-compatible APIs, lifecycle-aware components, and modern UI tools for building Android applications.
• Declarative UI Frameworks - Describes the user interface declaratively and automatically updates it when app state changes.
• Lifecycle-Aware Data Layers - Integrates LiveData, ViewModel, and Room to manage data lifecycle and persistence with less boilerplate.
• Compile-Time Verified Databases - Generates type-safe SQLite database access code from annotated interfaces at compile time.
• Background Task Schedulers - Runs deferred or periodic tasks while respecting system constraints like network and battery, offloading execution complexity.
• Backward Compatibility Libraries - Uses libraries that expose modern platform features on older Android versions so apps work consistently across devices.
• Compose Compiler Plugins - Transforms composable functions into UI code at compile time using Kotlin compiler extensions.
• Live Preview UI Development - Integrates with existing code and Android Studio to provide live previews and fast iteration during development.
• Constraint-Based Background Task Schedulers - Runs deferred background tasks while respecting system constraints like doze mode and battery saver.
• Background Task Execution - Moves work to background coroutines to keep the UI responsive and avoid jank.
• Android Activity Lifecycle Management - Builds lifecycle-aware components that adjust behavior based on current activity or fragment state.
• Composable Lifecycle APIs - Accesses composable APIs built on top of Activity for managing screen lifecycle events.
• Lifecycle-Aware Components - Provides opinionated, lifecycle-aware components that reduce boilerplate and make configuration changes easier to handle.
• Android App Navigation - Manages in-app navigation with a configurable, type-safe system that eliminates common anti-patterns.
• App Navigation Frameworks - Ships a navigation component for managing screen transitions, deep links, and routing.
• Declarative Data Bindings - Binds UI components to data sources using a declarative format to automate state updates.
• Android Development Boilerplate Reductions - Handles tedious work like managing background tasks, navigation, and activity lifecycle automatically.
• Dynamic Component Lifecycles - Adjusts component behavior based on the current lifecycle state of an activity or fragment.
• Lifecycle-Aware Data Observers - Exposes observable data holders that automatically respect the Android lifecycle, preventing memory leaks and crashes.
• Android Lifecycle Management - Manages Android component lifecycles automatically to prevent memory leaks and crashes.
• Lifecycle-Aware Data Observers - Emits data updates to observers while automatically respecting lifecycle states.
• Material Design Components - Provides ready-to-use Material Design components for building UIs that match the specification.
• Material Design Systems - Provides built-in support for Material Design, dark theme, animations, and adaptive layouts.
• Flexible Layout Constraints - Positions widgets using relative constraints for flexible, responsive layouts.
• Constraint-Based Layout Systems - Positions child views using relative constraints in a flat view hierarchy for flexible layouts.
• Lifecycle-Aware State Holders - Preserves UI-related data across configuration changes using a lifecycle-scoped container.
• Navigation Graph DSLs - Defines screen transitions declaratively using a type-safe Kotlin DSL with compile-time validation.
• Adaptive UI Layouts - Provides responsive components that automatically adjust layouts to any screen size.
• UI State Management - Applies patterns to handle and update application state within a declarative user interface.
• RecyclerView Pagination - Presents large datasets incrementally by loading pages of data into a RecyclerView.
• In-App Search Providers - Creates custom in-app search capabilities that let users find content within the application.
• AI Assistant Integrations - Exposes app features and data to AI assistants so they can discover and execute tasks on the device.
• Backward-Compatible Bluetooth APIs - Calls platform Bluetooth APIs through a backward-compatible interface to discover and connect to nearby devices.
• Camera App Frameworks - Provides backward-compatible APIs for building camera applications on Android.
• App Generation Templates - Generates templated applications for Android Auto and Android Automotive OS.
• Wear OS - Provides a specialized toolkit for building user interfaces on Wear OS devices.
• Animations - Provides animation APIs for building transitions and interactive state changes in Compose.
• Small-Buffer Optimizations - Reduces memory impact of small collections with optimized data structures.
• Biometric Authentication - Verifies user identity using biometrics or device credentials and performs cryptographic operations.
• AndroidX Dependency Injection Extensions - Extends Dagger Hilt to provide dependency injection for classes from the AndroidX libraries.
• Performance Benchmarkers - Accurately benchmarks code execution within Android Studio to identify performance characteristics.
• Android Environment Testing - Provides testing tools and frameworks for Android applications.
• Autofill Hints - Extends autofill hints so the system can fill form fields more precisely.
• Declarative and View-Based Interop - Provides interoperability between declarative Compose and traditional View-based UIs.
• Background Layout Inflations - Loads layout files in the background to prevent UI jank during inflation.
• Official Projects - Official development environment and source code for the toolkit.
• Core Frameworks - The official source for core framework libraries and components.
