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.
