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.

Provides device administration features at the system level, allowing you to create security-aware applications that are useful in enterprise settings, in which IT professionals require rich control over employee devices.

For more information, see the Device Administration 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 and publishing data on a device.

Contains classes for accessing application resources, such as raw asset files, colors, drawables, media or other other files in the package, plus important device configuration details (orientation, input types, etc.) that affect how the application may behave.

For more information, see the Application Resources guide.

Provides classes to manage a variety of visual elements that are intended for display only, such as bitmaps and gradients.

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

Provides classes that allow you to apply a variety of visual effects to images and videos.

Provides access to Session Initiation Protocol (SIP) functionality, such as making and answering VOIP calls using SIP.

For more information, see the Session Initiation Protocol developer guide.

Provides classes to create peer-to-peer (P2P) connections with Wi-Fi Direct.

Provides access to Near Field Communication (NFC) functionality, allowing applications to read NDEF message in NFC tags. A "tag" may actually be another device that appears as a tag.

For more information, see the Near Field Communication guide.

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).

Provides convenience classes to access the content providers supplied by Android.

A framework for writing Android test cases and suites.

For more information, see the Testing developer guide.

Provides classes used to view or change the style of a span of text in a View object.

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.

Provides classes related to Dalvik bytecode.

This package is for compatibility with legacy code only, and should not be used or expected to do anything useful.

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.

XML/Java Type Mappings.

This package implements DOM-specific transformation APIs.

This package implements stream- and URI- specific transformation APIs.

This package provides an object-model neutral API for the evaluation of XPath expressions and access to the evaluation environment.

This package contains interfaces to SAX2 facilities that conformant SAX drivers won't necessarily support.
