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.

Provides classes that manage Bluetooth functionality, such as scanning for devices, connecting with devices, and managing data transfer between devices. The Bluetooth API supports both "Classic Bluetooth" and Bluetooth Low Energy.

For more information about Classic Bluetooth, see the Bluetooth guide. For more information about Bluetooth Low Energy, see the Bluetooth Low Energy (BLE) 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.

The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device.

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.

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

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.

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

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

For more information, see the Testing guide.

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

The classes in this package enable "scenes & transitions" functionality for view hiearchies.

Provides classes that handle tweened animations.

The widget package contains (mostly visual) UI elements to use on your Application screen.

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.

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

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.
