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 developer 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 developer 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 developer 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 developer 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 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 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 developer 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.

Provides classes that allow you to create spell checkers in a manner similar to the input method framework (for IMEs).

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 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 all the classes and interfaces needed to implement and program the Secure Socket abstraction based on the SSL protocol SSSLv3.0 or TLSv1.2.

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.
