+page.title=ADT Plugin Notes
+@jd:body
+
+<p>Android Development Tools (ADT) is a development plugin for the Eclipse IDE. It
+extends the capabilites of Eclipse to let you quickly set up new Android
+projects, create an application UI, add components based on the Android
+Framework API, debug your applications using the Android SDK tools, and even export
+signed (or unsigned) APKs in order to distribute your application.</p>
+
+<p>This document provides version-specific information about ADT releases. To
+keep up-to-date on new releases, make sure that you view this page at <a
+href="http://developer.android.com/sdk/adt-notes.html">http://developer.
+android.com/sdk/adt-notes.html</a>.</p>
+
+<p>To install ADT in your Eclipse IDE environment, use the Eclipse Update Site
+feature. For more information, see <a
+href="{@docRoot}sdk/eclipse-adt.html">Installing and Updating ADT</a>. </p>
+

+<p>ADT 0.9.4 provides several new features for developers, as described below.
+</p>
+
+<h3>Dependencies</h3>
+
+<p>ADT 0.9.4 requires features provided in SDK Tools, Revision 3. If you install
+ADT 0.9.4, which is highly recommended, you should use the Android SDK and AVD
+Manager to download SDK Tools 3 or higher into your SDK. For more information,
+see <a href="{@docRoot}sdk/adding-components.html">Adding SDK Components</a>.
+</p>

+render on different devices. Default device descriptions include ADP1
+and Google Ion, while SDK add-ons can also provide new descriptions.
+A new UI allows you to create custom descriptions.</li>
+<li>Adds a new clipping toggle, to let you see your full layout even if it's
+bigger than the screen.</li>
+</ul>
+
+<h3>DDMS Integration</h3>
+<ul>
+<li>Includes the improvements from the standlone DDMS, revision 3.</li>
+<li>Adds an option to open HPROF files into eclipse instead of writing them on
