Installing the ADT Plugin

The sections below provide instructions on how to download and install ADT into your Eclipse environment. If you encounter problems, see the Troubleshooting section.

Preparing Your Development Computer

ADT is a plugin for the Eclipse IDE. Before you can install or use ADT, you must have a compatible version of Eclipse installed on your development computer. Check the System Requirements document for a list of Eclipse versions that are compatible with the Android SDK.

• If Eclipse is already installed on your computer, make sure that it is a version that is compatible with ADT and the Android SDK.
• If you need to install or update Eclipse, you can download it from this location:
  http://www.eclipse.org/downloads/
  The "Eclipse Classic" version is recommended. Otherwise, a Java or RCP version of Eclipse is recommended.

Additionally, before you can configure or use ADT, you must install the Android SDK starter package, as described in Downloading the SDK Starter Package. Specifically, you need to install a compatible version of the Android SDK Tools and at least one development platform. To simplify ADT setup, we recommend installing the Android SDK prior to installing ADT.

When your Eclipse and Android SDK environments are ready, continue with the ADT installation as described in the steps below.

Downloading the ADT Plugin

Use the Update Manager feature of your Eclipse installation to install the latest revision of ADT on your development computer.<>

Assuming that you have a compatible version of the Eclipse IDE installed, as described in Preparing for Installation, above, follow these steps to download the ADT plugin and install it in your Eclipse environment.
