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

For more information, see the USB guide.

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

For more information, 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.

These classes provide access to a tag technology's features, which vary by the type of tag that is scanned.

The Renderscript rendering and computational APIs offer a low-level, high performance means of carrying out mathematical calculations and 3D graphics rendering.

For more information, see the Renderscript developer guide.

Utility classes providing stubs or mocks of various Android framework building blocks.

For more information, see the Testing guide.

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

Provides classes that monitor or modify keypad input.

Provides classes that handle tweened animations.

Provides utility and system information classes specific to the Dalvik VM.

Provides the system's ReferenceQueue implementation as well as different forms of reference objects which impose special behavior on the garbage collector.

This package provides the classes and the interfaces needed to build Access Control Lists.

This package provides the interfaces needed to generate: (1) Keys for the RSA asymmetric encryption algorithm using the PKCS#1 standard; (2) Keys for the Digital Signature Algorithm (DSA) specified by FIPS-186; (3) Keys for a generic Elliptic Curve asymmetric encryption algorithm.

Provides a compatibility interface for accessing SQL-based databases.

This package provides the interfaces needed to implement the Diffie-Hellman (DH) key agreement's algorithm as specified by PKCS#3.

This package provides factory classes to create sockets and server-sockets.

This package provides a pluggable and stackable authentication system based on ideas and concepts from the Unix-PAM module.

This package is provided only for compatibility reasons.

Provides a utility class with useful XML constants.

XML Namespace processing.

This package defines the generic APIs for processing transformation instructions, and performing a transformation from source to result.

This package implements SAX2-specific transformation APIs.

This package provides an API for validation of XML documents.

Provides the official W3C Java bindings for the Document Object Model, level 2 core.

This package provides the core SAX APIs.

This package contains "helper" classes, including support for bootstrapping SAX-based applications.
