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.

Start Eclipse, then select Help > Install New Software....
Click Add, in the top-right corner.
In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location:
```
https://dl-ssl.google.com/android/eclipse/
```
Click OK
Note: If you have trouble acquiring the plugin, try using "http" in the Location URL, instead of "https" (https is preferred for security reasons).
In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
In the next window, you'll see a list of the tools to be downloaded. Click Next.
Read and accept the license agreements, then click Finish.
Note: If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
When the installation completes, restart Eclipse.

Configuring the ADT Plugin

After you've successfully downloaded the ADT as described above, the next step is to modify your ADT preferences in Eclipse to point to the Android SDK directory:

Select Window > Preferences... to open the Preferences panel (Mac OS X: Eclipse > Preferences).
Select Android from the left panel.

You may see a dialog asking whether you want to send usage statistics to Google. If so, make your choice and click Proceed. You cannot continue with this procedure until you click Proceed.

For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory.
Click Apply, then OK.

Done! If you haven't encountered any problems, then the installation is complete. If you're installing the Android SDK for the first time, return to Installing the SDK to complete your setup.

Troubleshooting ADT Installation

If you are having trouble downloading the ADT plugin after following the steps above, here are some suggestions:

If Eclipse can not find the remote update site containing the ADT plugin, try changing the remote site URL to use http, rather than https. That is, set the Location for the remote site to:
```
http://dl-ssl.google.com/android/eclipse/
```
If you are behind a firewall (such as a corporate firewall), make sure that you have properly configured your proxy settings in Eclipse. In Eclipse, you can configure proxy information from the main Eclipse menu in Window (on Mac OS X, Eclipse) > Preferences > General > Network Connections.

If you are still unable to use Eclipse to download the ADT plugin as a remote update site, you can download the ADT zip file to your local machine and manually install it:

Download the current ADT Plugin zip file from the table below (do not unpack it).

Name Package Size MD5 Checksum

ADT 10.0.1 ADT-10.0.1.zip 5096182 bytes e26a77db08377bdd2e62edeb9a3e3701
Follow steps 1 and 2 in the default install instructions (above).
In the Add Site dialog, click Archive.
Browse and select the downloaded zip file.
Enter a name for the local update site (e.g., "Android Plugin") in the "Name" field.
Click OK.
Follow the remaining procedures as listed for default installation above, starting from step 4.

Name	Package	Size	MD5 Checksum
ADT 10.0.1	ADT-10.0.1.zip	5096182 bytes	e26a77db08377bdd2e62edeb9a3e3701

To update your plugin once you've installed using the zip file, you will have to follow these steps again instead of the default update instructions.

Other install errors

Note that there are features of ADT that require some optional Eclipse components (for example, WST). If you encounter an error when installing ADT, your Eclipse installion might not include these components. For information about how to quickly add the necessary components to your Eclipse installation, see the troubleshooting topic ADT Installation Error: "requires plug-in org.eclipse.wst.sse.ui".

For Linux users

If you encounter this error when installing the ADT Plugin for Eclipse:

An error occurred during provisioning.
Cannot connect to keystore.
JKS

...then your development machine lacks a suitable Java VM. Installing Sun Java 6 will resolve this issue and you can then reinstall the ADT Plugin.

Updating the ADT Plugin

From time to time, a new revision of the ADT Plugin becomes available, with new features and bug fixes. Generally, when a new revision of ADT is available, you should update to it as soon as convenient.

In some cases, a new revision of ADT will have a dependency on a specific revision of the Android SDK Tools. If such dependencies exist, you will need to update the SDK Tools component of the SDK after installing the new revision of ADT. To update the SDK Tools component, use the Android SDK and AVD Manager, as described in Adding SDK Components.

To learn about new features of each ADT revision and also any dependencies on the SDK Tools, see the listings in the Revisions section. To determine the version currently installed, open the Eclipse Installed Software window using Help > Software Updates and refer to the version listed for "Android Development Tools".

Follow the steps below to check whether an update is available and, if so, to install it.

Select Help > Check for Updates.
If there are no updates available, a dialog will say so and you're done.
If there are updates available, select Android DDMS, Android Development Tools, and Android Hierarchy Viewer, then click Next.
In the Update Details dialog, click Next.
Read and accept the license agreement and then click Finish. This will download and install the latest version of Android DDMS and Android Development Tools.
Restart Eclipse.

If you encounter problems during the update, remove the existing ADT plugin from Eclipse, then perform a fresh installation, using the instructions for Installing the ADT Plugin.
