<p>Android offers a custom plugin for the Eclipse IDE, called Android

Development Tools (ADT). This plugin is designed to give you a powerful, integrated

Development Tools (ADT). This plugin provides a powerful, integrated

environment in which to develop Android apps. It extends the capabilities

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.

    <dt>Dependencies:</dt>

    <dd>

      <ul>

        <li>Android SDK Platform-tools revision 15 or later.</li>

        <li>If you are developing in Eclipse with ADT, note that the SDK Tools r21 is designed

        for use with ADT 21.0.0 and later. If you haven't already, update your

        <a href="{@docRoot}tools/sdk/eclipse-adt.html">ADT Plugin</a> to 21.0.0.</li>

        <li>If you are developing outside Eclipse, you must have

          <a href="http://ant.apache.org/">Apache Ant</a> 1.8 or later.</li>

    <dt>General Notes:</dt>

    <dd>

      <ul>

        <li>Build System

          <ul>

            <li>Added a flag that sets <em>jumbo mode</em> for DEX files, which allows a larger

              number of strings in the DEX files. Enable this mode by adding the following line to

              the {@code project.properties} file of your project:

              <pre>set dex.force.jumbo=true</pre></li>

            <li>Improved the build time by pre-dexing libraries (both JAR files and library

              projects).</li>

            <li>Updated the build to generate {@code R} resource classes for library projects

              with only the IDs needed by the libraries, reducing the risk of hitting DEX file

              limits for fields and methods.</li>

            <li>Improved the build so that several editing features (code completion, resource

              chooser, go to declaration) properly handle library project resources.</li>

          </ul>

        </li>

        <li>Lint

          <ul>

            <li>Added over 25 new lint rules for resources, locale settings, layout

              files, incorrect use of {@link android.util.SparseArray} and

              {@link android.os.PowerManager.WakeLock} and manifest issues.</li>

            <li>Updated reporting to include errors in library projects if the library project is

              in the list of projects to be checked.</li>

            <li>Added a new {@code lint} target to the Ant build system for easier

              integration with continuous build systems.</li>

            <li>Added new {@code --sources} and {@code --classpath} arguments to point to sources

              with different directory structures.</li>

            <li>Improved the XML export function to support the <a

              href="https://wiki.jenkins-ci.org/display/JENKINS/Android+Lint+Plugin">Jenkins Lint

              plugin</a>.

            </li>

            <li>Added support for class file flow analysis.</li>

          </ul>

        </li>

        <li>Android Virtual Devices (AVD)

          <ul>

            <li>Added new <strong>Device Definitions</strong> tab in the AVD Manager for configuring

              standard size and Nexus virtual devices.</li>

            <li>Improved emulators so that they launch with a skin that is dynamically generated and

              reflects the actual hardware configured in the AVD Manager.</li>

          </ul>

        </li>

        <li>Added {@code jobb} tool for creating and encrypting

          <a href="{@docRoot}guide/google/play/expansion-files.html">APK Expansion Files</a>.

          (<a href="{@docRoot}tools/help/jobb.html">more info</a>)

        <li>Improved the Android JUnit test runner to allow a test to be run on all connected

          devices simultaneously.</li>

      </ul>
