+SDK Tools, Revision 9</a> <em>(January 2011)</em>
+  <div class="toggleme">
+  <dl>
+<dt>Dependencies:</dt>
+<dd>
+<p>If you are developing in Eclipse with ADT, note that the SDK Tools r9 is
+designed for use with ADT 9.0.0 and later. After installing SDK Tools r9, we
+highly recommend updating your ADT Plugin to 9.0.0.</p>
+
+<p>If you are developing outside Eclipse, you must have <a href="http://ant.apache.org/">Apache
+Ant</a> 1.8 or later.</p>
+
+<dt>Upgrading to SDK Tools r9:</dt>
+<dd>
+<p>If you are upgrading to SDK Tools r9 from SDK Tools r7 or earlier, the default installed location
+for the <code>adb</code> tool has changed from <code>&lt;<em>SDK</em>&gt;/tools/adb</code> to
+<code>&lt;<em>SDK</em>&gt;/platform-tools/adb</code>. This means that you should
+add the new location to your PATH and modify any custom build scripts to
+reference the new location. Copying the <code>adb</code> executable from the new
+location to the old is not recommended, since subsequent updates to the SDK
+Tools will delete the file.</p>
+</dd>
+
+<dt>General notes:</dt>
+<dd>
+  <ul>
+    <li>The default ProGuard configuration, <code>proguard.cfg</code>, now ignores the following classes:
+      <ul>
+        <li>classes that extend {@link android.preference.Preference}</li>
+        <li>classes that extend {@link android.app.backup.BackupAgentHelper}</li>
+      </ul>
+    </li>
+    <li>Ant lib rules now allow you to override <code>java.encoding</code>, <code>java.source</code>,
+    and <code>java.target</code> properties.</li>
+    <li>The default encoding for the <code>javac</code> Ant task is now UTF-8.</li>
+    <li>The LogCat view in DDMS now properly displays UTF-8 characters.</li>
+    <li>The SDK Manager is more reliable on Windows. For details on the improvements, see the
+    <a href="http://tools.android.com/recent/sdkmanagerfixes">Android Tools Project Site</a>. </li>
+    <li>If you enabled snapshots for an AVD, they are automatically captured. The emulator also now restores to the state when
+     it last closed almost instantly.</li>
+    <li>Fixed the missing JAR file error that prevented <code>draw9patch</code> from running.</li>
+    <li>Fixed the Windows launch scripts <code>hierarchyviewer</code> and <code>ddms</code> to support
+    the new location of <code>adb</code>.</li>
+    <li>Known issues with emulator performance: Because the Android emulator must simulate the ARM
+instruction set architecture on your computer, emulator performance is  slow. We're working hard to
+resolve the performance issues and it will improve in future releases.</li>
