Download the Android SDK

Welcome Developers! If you are new to the Android SDK, please read the steps below, for an overview of how to set up the SDK.

If you're already using the Android SDK, you should update to the latest tools or platform using the Android SDK and AVD Manager, rather than downloading a new SDK starter package. See Adding SDK Components.

Here's an overview of the steps you must follow to set up the Android SDK:

Prepare your development computer and ensure it meets the system requirements.
Install the SDK starter package from the table above. (If you're on Windows, download the installer for help with the initial setup.)
Install the ADT Plugin for Eclipse (if you'll be developing in Eclipse).
Add Android platforms and other components to your SDK.
Explore the contents of the Android SDK (optional).
To get started, download the appropriate package from the table above, then read the guide to Installing the SDK.



Installing the SDK



Welcome to the Android SDK!

The Android SDK archive initially contains only the basic SDK tools. It does
not contain an Android platform or any third-party libraries. In fact, it
doesn't even have all the tools you need to develop an application.

In order to start developing applications, you must install the Platform-tools
and at least one version of the Android platform, using the SDK Manager.

Platform-tools contains build tools that are periodically updated to support new
features in the Android platform (which is why they are separate from basic
SDK tools), including adb, dexdump, and others.

To install Platform-tools, Android platforms and other add-ons, you must
have an Internet connection, so if you plan to use the SDK while
offline, please make sure to download the necessary components while online.

To start the SDK Manager, please execute the program "tools/android".

From the command-line you can also directly trigger an update by
executing:
tools/android update sdk
