Package Index - Android SDK

The classes in this package are used for development of accessibility service that provide alternative or augmented feedback to the user.

These classes provide functionality for the property animation system, which allows you to animate object properties of any type. int, float, and hexadecimal color values are supported by default. You can animate any other type by telling the system how to calculate the values for that given type with a custom TypeEvaluator.

For more information, see the Animation guide.

Contains high-level classes encapsulating the overall Android application model.

Contains the backup and restore functionality available to applications. If a user wipes the data on their device or upgrades to a new Android-powered device, all applications that have enabled backup can restore the user's previous data when the application is reinstalled.

For more information, see the Data Backup guide.

Contains the components necessary to create "app widgets", which users can embed in other applications (such as the home screen) to quickly access application data and services without launching a new activity.

For more information, see the App Widgets guide.

Contains classes for accessing information about an application package, including information about its activities, permissions, services, signatures, and providers.

Provides classes for managing DRM content and determining the capabilities of DRM plugins (agents).

Provides support for hardware features, such as the camera and other sensors.

Provides support to communicate with USB hardware peripherals that are connected to Android-powered devices.

For more information, see the USB guide.

Contains the framework API classes that define Android location-based and related services.

Note: The Google Location Services API, part of Google Play Services, provides a more powerful, high-level framework that automates tasks such as location provider choice and power management. Location Services also provides new features such as activity detection that aren't available in the framework API. Developers who are using the framework API, as well as developers who are just now adding location-awareness to their apps, should strongly consider using the Location Services API.
To learn more about the Location Services API, see Location APIs.

For more information about the framework API, see the Location and Maps guide.

Provides APIs that let you interact directly with connected cameras and other devices, using the PTP (Picture Transfer Protocol) subset of the MTP (Media Transfer Protocol) specification.

Provides APIs for RTP (Real-time Transport Protocol), allowing applications to manage on-demand or interactive data streaming.

Provides classes to manage Wi-Fi functionality on the device.

Provides an OpenGL ES static interface and utilities.

Contains classes for the system storage service, which manages binary asset filesystems known as Opaque Binary Blobs (OBBs).

Overview

Provides classes for implementing print support in applications and also contains all base classes and abstractions involved in printing.

Provides classes for implementing print services.

RenderScript provides support for high-performance computation across heterogeneous processors.

For more information, see the RenderScript developer guide.

Provides access to a few facilities of the Android security subsystems.

A framework for writing Android test cases and suites.

For more information, see the Testing developer guide.

Provides classes used to render or track text and text spans on the screen.

Provides classes that monitor or modify keypad input.

The classes in this package are used to represent screen content and changes to it as well as APIs for querying the global accessibility state of the system.

Provides tools for browsing the web.

Extensible cryptographic service provider infrastructure (SPI) for using and defining services such as Certificates, Keys, KeyStores, MessageDigests, and Signatures.

This package provides all the classes and all the interfaces needed to generate, administer and verify X.509 certificates.

This package provides the classes and interfaces needed to specify keys and parameters for encryption and signing algorithms.

This package provides the classes and interfaces for cryptographic applications implementing algorithms for encryption, decryption, or key agreement.

This package provides the classes and interfaces needed to specify keys and parameter for encryption.

Provides a standard OpenGL interface.

This package provides classes and interfaces needed to use the Secure Sockets Layer (SSL) protocol and the successor Transport Layer Security (TLS) protocol.

This package provides classes and interfaces needed to interact with the application in order to execute the authentication and authorization processes.

This package provides classes needed to store X.500 principals and their credentials.
