5 <p>SDK Tools is a downloadable component for the Android SDK. It includes the
6 complete set of development and debugging tools for the Android SDK.</p>
8 <p>If you are new to the Android SDK, the <a
9 href="{@docRoot}sdk/index.html">SDK starter package</a> installs the
10 latest revision of the SDK Tools in the <code><sdk>/tools</code> directory.</p>
12 <p>If you are already using the SDK and you want to update to the latest version
13 of the SDK Tools, use the <em>Android SDK Manager</em> to get the
14 update, rather than downloading a new SDK starter package. For more information
15 about how to update, see <a
16 href="{@docRoot}sdk/exploring.html#UpdatingComponents">Exploring the SDK</a>.</p>
19 <h2 id="notes">Revisions</h2>
21 <p>The sections below provide notes about successive releases of
22 the SDK Tools, as denoted by revision number. To determine what revision of the SDK
23 Tools you are using, refer to the "Installed Packages" listing in the Android SDK Manager. </p>

130 <li>Changed the structure of the SDK by adding a new build tool SDK Component, which is
131 based on the existing platform-tools component. This change decouples the build tools
132 versions from the IDE versions, allowing updates to the tools without requiring an

222 <li>Updated build to detect and handle package name conflicts between an application and
223 the libraries it depends on. Libraries cannot share package names unless all of them
224 share the same package name.
225 (<a href="http://code.google.com/p/android/issues/detail?id=40152">Issue 40152</a>,
226 <a href="http://code.google.com/p/android/issues/detail?id=40273">Issue 40273</a>)
228 <li>Added a flag to disable dex merging to deal with cases where merging could generate
229 a broken dex file. If this happens to your project, add the following setting to your
230 {@code project.properties} file: {@code dex.disable.merger=true} This setting
231 causes the build system to revert to the older, slower dex processing that does not
232 pre-dex libraries.</li>
238 <li>Added support for
239 <a href="{@docRoot}guide/topics/renderscript/compute.html#filterscript">Filterscript</a>
241 <li>Added new project setting to control the Renderscript compilation target separately
242 from an Android project. Adding the following line to a {@code project.properties}
243 file causes Renderscript code to be compiled for Android API Level 17, while the
244 containing application can target a different (lower) API level:
245 <pre>renderscript.target = 17</pre>
246 Previously, the Renderscript compilation target was tied to the
247 {@code android:minSdkVersion} setting in the manifest.
248 (<a href="http://code.google.com/p/android/issues/detail?id=40487">Issue 40487</a>)

328 <pre>set dex.force.jumbo=true</pre></li>
329 <li>Improved the build time by pre-dexing libraries (both JAR files and library
331 <li>Updated the build to generate {@code R} resource classes for library projects
332 with only the IDs needed by the libraries, reducing the risk of hitting DEX file
333 limits for fields and methods.</li>

335 chooser, go to declaration) properly handle library project resources.</li>
340 <li>Added over 25 new lint rules for resources, locale settings, layout
341 files, incorrect use of {@link android.util.SparseArray} and

361 reflects the actual hardware configured in the AVD Manager.</li>
362 <li>Improved support for developing Android apps on MIPS-based devices with new MIPS
363 System Images for Android Virtual Devices.</li>

479 to capture a slice of system activity, plus additional information tagged from the <strong>Settings
480 > Developer Options > Monitoring: Enable traces</strong> or with specific calls added to your
481 application code.</li>
485 <li>Added automatic merging of library project manifest files into the including
486 project's manifest. Enable this feature with the {@code manifestmerger.enabled} property.</li>
487 <li>Added automatic ProGuard support for the {@code aapt -G} flag. This change causes
488 the build system to generate a temporary ProGuard {@code keep-rules} file containing classes that
489 are referenced from XML files (such as custom views) and pass this to ProGuard at shrink time. This
490 can make the resulting APK much smaller when using just a small portion of a large library project

657 kept in project and the generic Android flags distributed (and updated) with the tools
663 <li>Added a feature that allows you to run some code only in debug mode. Builds now
664 generate a class called {@code BuildConfig} containing a {@code DEBUG} constant that is
665 automatically set according to your build type. You can check the ({@code BuildConfig.DEBUG})

667 <li>Fixed issue when a project and its libraries include the same jar file in their libs
668 folder. (<a href="http://tools.android.com/recent/dealingwithdependenciesinandroidprojects">more
670 <li>Added support for custom views with custom attributes in libraries. Layouts using

672 of the URI that includes the app package name. This URI is replaced with the app specific one at
678 <li>Updated Lint to check Android application code. Lint rules which previously
679 performed pattern based searches in the application code (such as the unused resource check) have
680 been rewritten to use the more accurate Java-style parse trees.</li>
681 <li>Added support for checking library projects. This change means that rules such as
682 the unused resource check properly handle resources declared in a library project and referenced in
683 a downstream project.</li>
684 <li>Added ability to suppress Lint warnings in Java code with the new

995 <dt>Upgrading to SDK Tools r9:</dt>
997 <p>If you are upgrading to SDK Tools r9 from SDK Tools r7 or earlier, the default installed location
998 for the <code>adb</code> tool has changed from <code><<em>SDK</em>>/tools/adb</code> to
999 <code><<em>SDK</em>>/platform-tools/adb</code>. This means that you should
1000 add the new location to your PATH and modify any custom build scripts to
1001 reference the new location. Copying the <code>adb</code> executable from the new
1002 location to the old is not recommended, since subsequent updates to the SDK
1003 Tools will delete the file.</p>
1006 <dt>General notes:</dt>
1009 <li>The default ProGuard configuration, <code>proguard.cfg</code>, now ignores the following classes:

1017 <li>The default encoding for the <code>javac</code> Ant task is now UTF-8.</li>
1018 <li>The LogCat view in DDMS now properly displays UTF-8 characters.</li>
1019 <li>The SDK Manager is more reliable on Windows. For details on the improvements, see the
1020 <a href="http://tools.android.com/recent/sdkmanagerfixes">Android Tools Project Site</a>. </li>
1021 <li>Early look at the new snapshot feature: To improve startup time for the emulator, you can
1022 enable snapshots for the system state. The emulator will then restore to the state when it last
1023 closed almost instantly. <strong>Note:</strong> The snapshot feature is still under active
1024 development and might not always perform as expected.</li>

1026 <li>Fixed the Windows launch scripts <code>hierarchyviewer</code> and <code>ddms</code> to support
1027 the new location of <code>adb</code>.</li>
1028 <li>Known issues with emulator performance: Because the Android emulator must simulate the ARM
1029 instruction set architecture on your computer, emulator performance is slow. We're working hard to
1030 resolve the performance issues and it will improve in future releases.</li>

1045 <dt>Dependencies:</dt>
1047 <p>If you are developing in Eclipse with ADT, note that SDK Tools r8 is
1048 designed for use with ADT 8.0.0 and later. After installing SDK Tools r8, we
1049 highly recommend updating your ADT Plugin to 8.0.0.</p>

1054 <p>Also note that SDK Tools r8 requires a new SDK component called
1055 <em>Platform-tools</em>. The new Platform-tools component lets all SDK platforms
1056 (Android 2.1, Android 2.2, and so on) use the same (latest) version of build
1057 tools such as <code>adb</code>, <code>aapt</code>, <code>aidl</code>, and
1058 <code>dx</code>. To download the Platform-tools component, use the Android SDK
1059 Manager, as described in <a href="{@docRoot}sdk/exploring.html">Exploring the
1062 <dt>Upgrading from SDK Tools r7:</dt>
1064 <p>If you are upgrading to SDK Tools r8 from an earlier version, note that the
1065 the default installed location for the <code>adb</code> tool has changed from
1066 <code><<em>SDK</em>>/tools/adb</code> to

1074 <dt>General notes:</dt>
1077 <li>All SDK platforms now support Library Projects.</li>
1078 <li>Support for a true debug build. Developers no longer need to add the
1079 <code>android:debuggable</code> attribute to the
1080 <code><application></code> tag in the manifest — the build tools add
1081 the attribute automatically. In Eclipse/ADT, all incremental builds are assumed
1082 to be debug builds, so the tools insert <code>android:debuggable="true"</code>.
1083 When exporting a signed release build, the tools do not add the attribute. In
1084 Ant, a <code>ant debug</code> command automatically inserts the
1085 <code>android:debuggable="true"</code> attribute, while <code>ant release</code>
1086 does not. If <code>android:debuggable="true"</code> is manually set, then
1087 <code>ant release</code> will actually do a debug build, rather than a release
1089 <li>Automatic ProGuard support in release builds. Developers generate a ProGuard
1090 configuration file using the <code>android</code> tool — the build tools
1091 then automatically run ProGuard against the project sources during the build.
1092 For more information, see the <a
1093 href="{@docRoot}tools/help/proguard.html">ProGuard</a>
1094 documentation. </li>
1095 <li>New overridable Ant javac properties: <code>java.encoding</code>,
