android development: Collection of libraries in android

Android Libraries for developing the application. Core APIs for android
Android offers a number of APIs for developing your applications. The following list of core APIs
should provide an insight into what’s available; all Android devices will offer support for at least
these APIs:
android libraries, android library
android framework

❑ android.util The core utility package contains low-level classes like specialized containers,
string formatters, and XML parsing utilities.
❑ android.os The operating system package provides access to basic operating system services
like message passing, interprocess communication, clock functions, and debugging.

colors, and drawing primitives, and lets you draw on canvases.

with databases.
❑ android.content The content API is used to manage data access and publishing by providing
services for dealing with resources, content providers, and packages.

using a series of Views to provide the user interaction components.

you can use within your application. Includes the MapView control as well as the Overlay and
MapController classes used to annotate and control your embedded maps.
❑ android.app A high-level package that provides access to the application model. The application
package includes the Activity and Service APIs that form the basis for all your Android
❑ android.provider To ease developer access to certain standard Content Providers (such as the
contacts database), the Provider package offers classes to provide access to standard databases
included in all Android distributions.
❑ android.telephony The telephony APIs give you the ability to directly interact with the device’s
phone stack, letting you make, receive, and monitor phone calls, phone status, and SMS messages.
❑ android.webkit The WebKit package features APIs for working with Web-based content,
