This is the higher level entry point of Compose, designed to provide components that match those described at www.material.io. compose.material3 Build Jetpack Compose UIs with Material Design 3 Components, the next evolution of Material Design. Material 3 includes updated theming and components and Material You personalization features like dynamic color, and is designed to be cohesive with the new Android 12 visual style and system UI. compose.runtime Fundamental building blocks of Compose’s programming model and state management, and core runtime for the Compose Compiler Plugin to target. compose.ui Fundamental components of compose UI needed to interact with the device, including layout, drawing, and input. concurrent Move tasks off the main thread with coroutines and take advantage of ListenableFuture. constraintlayout Position and size widgets in a flexible way with relative positioning. contentpager Load and page across ContentProvider data in a background thread. coordinatorlayout Position top-level application widgets, such as AppBarLayout and FloatingActionButton. core Target the latest platform features and APIs while also supporting older devices. core.uwb Implement UWB (ultra-wideband) on supported devices. credentials This library provides unified access to a user’s credentials. This can include passwords, passkeys and federated credentials. This library should be used to provide seamless and secure sign-in experiences. cursoradapter Expose Cursor data to a ListView widget. customview Implement custom views. datastore Store data asynchronously, consistently, and transactionally, overcoming some of the drawbacks of SharedPreferences documentfile View a file document. draganddrop Accept drag-and-drop data from another app or within an app, and show a consistent drop target affordance. drawerlayout Implement a Material Design drawer widget. dynamicanimation Create smooth animations with a physics-based animation API. emoji Display emoji in current and older devices. emoji2 Display emoji in current and older devices. enterprise Create enterprise-ready applications. exifinterface Read and write image file EXIF tags. games Use the Android Game SDK natively in your app to perform complex games tasks, like Frame Pacing. glance Build layouts for remote surfaces using a Jetpack Compose-style API. graphics Leverage graphics facilities across multiple Android platform releases gridlayout Implement a grid layout. health Create performant health applications in a platform agnostic way. health.connect Allows developers to read or write user’s health and fitness records. heifwriter Encode an image or image collection in HEIF format using the available codecs on the Android device. input Reduce the latency of input interactions by predicting future MotionEvents interpolator Use animation interpolators on older platforms. javascriptengine Enable your Android app to evaluate JavaScript. jetifier A standalone tool that migrates a library’s dependencies on the deprecated support library to equivalent AndroidX dependencies. leanback Write apps for Android TV devices using dpad-friendly widgets and template fragments. legacy This artifact and its classes are deprecated. Starting with Android 8, background check restrictions make this class no longer useful. loader Load data for your UI that survives configuration changes. localbroadcastmanager This artifact and its classes are deprecated. Use LiveData or reactive streams instead. media Share media contents and controls with other apps. Superseded by media2. media2 Share media contents and controls with other apps. media3 * Support libraries for media use cases. mediarouter Enable media display and playback on remote receiver devices using a common user interface. multidex Deploy applications with multiple dex files on pre-Android 5 devices. metrics Track and report various runtime metrics for your application palette Extract representative color palettes from images. percentlayout This artifact and its classes are deprecated. Use ConstraintLayout and associated layouts instead. preference Build interactive settings screens without needing to interact with device storage or manage the UI. print Print photos, docs, and other graphics and images from your app. privacysandbox.ads This library enables integration with Privacy Preserving APIs, which are part of Privacy Sandbox on Android. privacysandbox.plugins Android Privacy Sandbox Sdk Library Gradle Plugin privacysandbox.sdkruntime This library provides components for SdkRuntime aware consumers privacysandbox.tools A library to utilize the Privacy Sandbox functionality in Android profileinstaller Enables libraries to prepopulate ahead of time compilation traces to be read by ART. recommendation Promote content to the Android TV Launcher home screen. recyclerview Display large sets of data in your UI while minimizing memory usage. remotecallback Create a wrapper that makes it easier for developers to provide a PendingIntent. resourceinspection Surface the attributes of custom views in Android Studio’s Live Layout Inspector. savedstate Write pluggable components that save the UI state when a process dies, and restore it when the process restarts. security Safely manage keys and encrypt files and sharedpreferences. sharetarget Provide backwards compatibility for using shortcuts as direct share targets. slice Display templated UI elements outside your app. slidingpanelayout Implement a sliding pane UI pattern. startup Implement a straightforward, performant way to initialize components at app startup. sqlite Work with local SQLite databases.
