Installing the Eclipse Plugin

Android offers a custom plugin for the Eclipse IDE, called Android Development Tools (ADT). This plugin is designed to give you a powerful, integrated environment in which to develop Android apps. It extends the capabilites of Eclipse to let you quickly set up new Android projects, build an app UI, debug your app, and export signed (or unsigned) app packages (APKs) for distribution.

If you will be developing in Eclipse with the ADT Plugin, first make sure that you have a suitable version of Eclipse installed on your computer as described by the system requirements.

If you need to install Eclipse, you can download it from We recommend the "Eclipse Classic" version. Otherwise, you should use a Java or RCP version of Eclipse.

Note: If you prefer to work in a different IDE, you do not need to install Eclipse or ADT. Instead, you can directly use the SDK tools to build and debug your application. So if you're not using Eclipse, continue to the next page by clicking the 后一个 link on the right.

Download the ADT Plugin

  1. Start Eclipse, then select Help > Install New Software....
  2. Click Add, in the top-right corner.
  3. In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location:
  4. 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).

  5. In the Available Software dialog, select the checkbox next to Developer Tools and click 后一个.
  6. In the next window, you'll see a list of the tools to be downloaded. Click 后一个.
  7. 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.

  8. When the installation completes, restart Eclipse.

Configure the ADT Plugin

After you've installed ADT and restarted Eclipse, you must specify the location of your Android SDK directory:

  1. Select Window > Preferences... to open the Preferences panel (on Mac OS X, select Eclipse > Preferences).
  2. Select Android from the left panel.
  3. You may see a dialog asking whether you want to send usage statistics to Google. If so, make your choice and click Proceed.

  4. For the SDK Location in the main panel, click Browse... and locate your downloaded Android SDK directory (such as android-sdk-windows).
  5. Click Apply, then OK.

If you haven't encountered any errors, you're done setting up ADT and can continue to the next step of the SDK installation.

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 package of the SDK after installing the new revision of ADT. To update the SDK Tools package, use the Android SDK Manager, as described in Exploring the SDK.

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.

  1. Select Help > Check for Updates.

    If there are no updates available, a dialog will say so and you're done.

  2. If there are updates available, select Android DDMS, Android Development Tools, and Android Hierarchy Viewer, then click 后一个.
  3. In the Update Details dialog, click 后一个.
  4. 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.
  5. 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.


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:
  • 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:

  1. Download the current ADT Plugin zip file from the table below (do not unpack it).
    Name Package Size MD5 Checksum
    ADT 20.0.0 12387628 bytes ea0fc934af3b6b89097f0146c7822ed0
  2. Follow steps 1 and 2 in the default install instructions (above).
  3. In the Add Site dialog, click Archive.
  4. Browse and select the downloaded zip file.
  5. Enter a name for the local update site (e.g., "Android Plugin") in the "Name" field.
  6. Click OK.
  7. Follow the remaining procedures as listed for default installation above, starting from step 4.

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 packages (for example, WST). If you encounter an error when installing ADT, your Eclipse installion might not include these packages. For information about how to quickly add the necessary packages 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.

...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.
