Before installing the Android SDK, you must agree to the following terms and conditions.
Now that you've downloaded the Android SDK, you don't need to return here for SDK updates. The SDK tools allow you to install additional packages and future updates from the SDK Manager.
For instructions about setting up your Android SDK for the first time, read Setting Up the ADT Bundle.
The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android.
If you're a new Android developer, we recommend you download the ADT Bundle to quickly start developing apps. It includes the essential Android SDK components and a version of the Eclipse IDE with built-in ADT (Android Developer Tools) to streamline your Android app development.
With a single download, the ADT Bundle includes everything you need to begin developing apps:
To get the ADT Bundle or stand-alone SDK Tools, please visit the web site at developer.android.com/sdk/
If you prefer to use an existing version of Eclipse or another IDE, you can instead take a more customized approach to installing the Android SDK. See the following instructions.
If you already have an IDE you want to use for Android app development, setting up a new SDK requires that you download the SDK Tools, then select additional Android SDK packages to install (such as the Android platform and system image). If you'll be using an existing version of Eclipse, then you can add the ADT plugin to it.
Note: Eclipse 3.5 (Galileo) is no longer supported with the latest version of ADT.
Note: Some Linux distributions may include JDK 1.4 or Gnu Compiler for Java, both of which are not supported for Android development.
