Android is a software stack for mobile devices that includes an operating system, middleware, and key applications. The Android SDK provides the tools and libraries necessary to begin developing applications that run on Android-powered devices.
This site provides information about Google projects based on the Android platform, such as external libraries that extend the platform, hosted services and APIs, and more. Everything on this site is provided by Google for the benefit of Android developers. If you are interested in developing applications for Android devices, please visit the Android Developers site at developer.android.com.
The Google APIs add-on extends your Android SDK to give your applications access to Google libraries such as Maps. Using the Maps library, you can quickly add powerful mapping capabilities to your Android applications.
C2DM has been deprecated and replaced by Google Cloud Messaging for Android (GCM). This means that C2DM has stopped accepting new users and quota requests. No new features will be added to C2DM. However, apps using C2DM will continue to work. Existing C2DM developers are encouraged to migrate to GCM. See the C2DM-to-GCM Migration document for more information. Developers must use GCM for new development.
Google Play services brings Google APIs, such as Google+, to your Android apps with support for an authentication flow that makes it easy for you and your users to request and grant credentials. Google Play services are delivered through the Google Play Store and Android 2.2 or later devices receive these new features without waiting for carrier or OEM updates. You’ll get to use new features in your apps and be confident your users’ devices will support them.
