For a summary of all known issues in SDK Tools, see http://tools.android.com/knownissues.

SDK Tools, Revision 21.1.0(February 2013)

• Android SDK Platform-tools revision 16 or later.
• If you are developing in Eclipse with ADT, note that the SDK Tools r21.1.0 is designed for use with ADT 21.1.0 and later. If you haven't already, update your ADT Plugin to 21.1.0.
• If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.

• Improved error reporting in dx when dex merging fails in the build system.
• Added more than 15 new Lint checks, including checks for overriding older APIs, XML resource problems, graphic asset issues and manifest tags.
• Added new aapt feature to compile resources.

SDK Tools, Revision 21.0.1(December 2012)

• Android SDK Platform-tools revision 16 or later.
• If you are developing in Eclipse with ADT, note that the SDK Tools r21.0.1 is designed for use with ADT 21.0.1 and later. If you haven't already, update your ADT Plugin to 21.0.1.
• If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.

• Build
  • Updated build to detect and handle package name conflicts between an application and the libraries it depends on. Libraries cannot share package names unless all of them share the same package name. (Issue 40152, Issue 40273)
  • Added a flag to disable dex merging to deal with cases where merging could generate a broken dex file. If this happens to your project, add the following setting to your project.properties file: dex.disable.merger=true This setting causes the build system to revert to the older, slower dex processing that does not pre-dex libraries.
• Renderscript
  • Added support for Filterscript compilation.
  • Added new project setting to control the Renderscript compilation target separately from an Android project. Adding the following line to a project.properties file causes Renderscript code to be compiled for Android API Level 17, while the containing application can target a different (lower) API level: Previously, the Renderscript compilation target was tied to the android:minSdkVersion setting in the manifest. (Issue 40487)

• Lint
  • Corrected check for 0px values in style XML elements. (Issue 39601)
  • Fixed incorrect flagging of formatting strings. (Issue 39758)
  • Fixed problem where tools:ignore directive in the manifest file was ignored by the Lint tool. (Issue 40136)
  • Fixed problem with flagging a wakelock release inside a conditional. (Issue 40424)
  • Fixed incorrect reporting of missing layout_width and layout_height XML fields. (Issue 38958)
  • Fixed handling of custom namespace attributes.
  • Added fixes for filtering out library project warnings.
  • Removed warnings about missing classes before a build.
• Fixed problem with UI Automator Viewer execution script where Android tools directory is not set.
• Fixed problem with the SDK Manager so that it auto-selects the most recently released platform on startup.
• Fixed Java finding script to look for the currently supported version of Java (1.6 or higher).
• Fixed the SDK Manager launcher in the ADT bundle so that it can properly launch the SDK Manager program when it is placed at the root of the bundle.

SDK Tools, Revision 21(November 2012)

• Android SDK Platform-tools revision 16 or later.
• 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 ADT Plugin to 21.0.0.
• If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.

• Build System
  • Added a flag that sets jumbo mode for DEX files, which allows a larger number of strings in the DEX files. Enable this mode by adding the following line to the project.properties file of your project:
  • Improved the build time by pre-dexing libraries (both JAR files and library projects).
  • Updated the build to generate 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.
  • Improved the build so that several editing features (code completion, resource chooser, go to declaration) properly handle library project resources.
• Lint
  • Added over 25 new lint rules for resources, locale settings, layout files, incorrect use of SparseArray and PowerManager.WakeLock and manifest issues.
  • Updated reporting to include errors in library projects if the library project is in the list of projects to be checked.
  • Added a new lint target to the Ant build system for easier integration with continuous build systems.
  • Added new --sources and --classpath arguments to point to sources with different directory structures.
  • Improved the XML export function to support the Jenkins Lint plugin.
  • Added support for class file flow analysis.
• Android Virtual Devices (AVD)
  • Added new Device Definitions tab in the AVD Manager for configuring standard size and Nexus virtual devices.
  • Improved emulators so that they launch with a skin that is dynamically generated and reflects the actual hardware configured in the AVD Manager.
  • Improved support for developing Android apps on MIPS-based devices with new MIPS System Images for Android Virtual Devices.
• Added jobb tool for creating and encrypting APK Expansion Files. (more info)
• Improved the Android JUnit test runner to allow a test to be run on all connected devices simultaneously.

• Fixed manifest merger to properly adapt library classes in the merged manifest.

SDK Tools, Revision 20.0.3(August 2012)

• Android SDK Platform-tools revision 12 or later.
• If you are developing in Eclipse with ADT, note that the SDK Tools r20.0.3 is designed for use with ADT 20.0.3 and later. If you haven't already, update your ADT Plugin to 20.0.3.
• If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.

• Added new Device Monitor application, grouping Android debugging tools into asingle application, including ddms, traceview, hierarchyviewer and Tracer for GLES. (more info)
• Added new System Trace new tool for tracing Android system activity. This tool allow youto capture a slice of system activity, plus additional information tagged from the Settings> Developer Options > Monitoring: Enable traces or with specific calls added to yourapplication code.
• Build System
  • Added automatic merging of library project manifest files into the includingproject's manifest. Enable this feature with the manifestmerger.enabled property.
  • Added automatic ProGuard support for the aapt -G flag. This change causesthe build system to generate a temporary ProGuard keep-rules file containing classes thatare referenced from XML files (such as custom views) and pass this to ProGuard at shrink time. Thiscan make the resulting APK much smaller when using just a small portion of a large library project(such as the Android Support library), since the catch-all rules to keep all custom views from thedefault ProGuard configuration file have also been removed.
  • Added two ProGuard configuration files for use in projects: proguard-android-optimize.txt which enables optimizations and proguard-android.txt whichdisables them.
• SDK Manager
  • Improved caching to reduce downloading of repository definitions.
  • Added Tools > Manage Add-on Sites option to improve performance by allowing temporary deactivation of third-party sites if they are loading slowly.

SDK Tools, Revision 10(February 2011)

If you are developing in Eclipse with ADT, note that the SDK Tools r10 isdesigned for use with ADT 10.0.0 and later. After installing SDK Tools r10, wehighly recommend updating your ADT Plugin to 10.0.0.

If you are developing outside Eclipse, you must have ApacheAnt 1.8 or later.

• The tools now automatically generate Java Programming Language source files (in thegen directory) and bytecode (in the res/raw directory) from your native .rs files

SDK Tools, Revision 9(January 2011)

If you are developing in Eclipse with ADT, note that the SDK Tools r9 isdesigned for use with ADT 9.0.0 and later. After installing SDK Tools r9, wehighly recommend updating your ADT Plugin to 9.0.0.

If you are developing outside Eclipse, you must have ApacheAnt 1.8 or later.

If you are upgrading to SDK Tools r9 from SDK Tools r7 or earlier, the default installed locationfor the adb tool has changed from <SDK>/tools/adb to<SDK>/platform-tools/adb. This means that you shouldadd the new location to your PATH and modify any custom build scripts toreference the new location. Copying the adb executable from the newlocation to the old is not recommended, since subsequent updates to the SDKTools will delete the file.

• The default ProGuard configuration, proguard.cfg, now ignores the following classes:
  • classes that extend Preference
  • classes that extend BackupAgentHelper
• Ant lib rules now allow you to override java.encoding, java.source, and java.target properties.
• The default encoding for the javac Ant task is now UTF-8.
• The LogCat view in DDMS now properly displays UTF-8 characters.
• The SDK Manager is more reliable on Windows. For details on the improvements, see the Android Tools Project Site.
• Early look at the new snapshot feature: To improve startup time for the emulator, you canenable snapshots for the system state. The emulator will then restore to the state when it lastclosed almost instantly. Note: The snapshot feature is still under activedevelopment and might not always perform as expected.
• Fixed the missing JAR file error that prevented draw9patch from running.
• Fixed the Windows launch scripts hierarchyviewer and ddms to support the new location of adb.
• Known issues with emulator performance: Because the Android emulator must simulate the ARMinstruction set architecture on your computer, emulator performance is slow. We're working hard toresolve the performance issues and it will improve in future releases.

SDK Tools, Revision 8(December 2010)

If you are developing in Eclipse with ADT, note that SDK Tools r8 isdesigned for use with ADT 8.0.0 and later. After installing SDK Tools r8, wehighly recommend updating your ADT Plugin to 8.0.0.

If you are developing outside Eclipse, you must have ApacheAnt 1.8 or later.

Also note that SDK Tools r8 requires a new SDK component calledPlatform-tools. The new Platform-tools component lets all SDK platforms(Android 2.1, Android 2.2, and so on) use the same (latest) version of buildtools such as adb, aapt, aidl, anddx. To download the Platform-tools component, use the Android SDKManager, as described in Exploring theSDK

If you are upgrading to SDK Tools r8 from an earlier version, note that thethe default installed location for the adb tool has changed from<SDK>/tools/adb to<SDK>/platform-tools/adb. This means that you shouldadd the new location to your PATH and modify any custom build scripts toreference the new location. Copying the adb executable from the newlocation to the old is not recommended, since subsequent updates to the SDKTools will delete the file.

• All SDK platforms now support Library Projects.
• Support for a true debug build. Developers no longer need to add theandroid:debuggable attribute to the<application> tag in the manifest — the build tools addthe attribute automatically. In Eclipse/ADT, all incremental builds are assumedto be debug builds, so the tools insert android:debuggable='true'.When exporting a signed release build, the tools do not add the attribute. InAnt, a ant debug command automatically inserts theandroid:debuggable='true' attribute, while ant releasedoes not. If android:debuggable='true' is manually set, thenant release will actually do a debug build, rather than a releasebuild.
• Automatic ProGuard support in release builds. Developers generate a ProGuardconfiguration file using the android tool — the build toolsthen automatically run ProGuard against the project sources during the build.For more information, see the ProGuarddocumentation.
• New overridable Ant javac properties: java.encoding,java.source, and java.target (default values are'ascii', '1.5', and '1.5', respectively).
• New UI for the HierarchyViewer tool.

SDK Tools, Revision 7(September 2010)

If you are developing in Eclipse with ADT, note that SDK Tools r7 isdesigned for use with ADT 0.9.8 and later. After installing SDK Tools r7, wehighly recommend updating your ADT Plugin to 0.9.8.

• Added support for library projects that depend on other library projects.
• Adds support for aidl files in library projects.
• Adds support for extension targets in Ant build to perform tasks between thenormal tasks: -pre-build, -pre-compile, and-post-compile.
• Adds support for 'headless' SDK update. See android -h update sdkfor more information.
• Fixes location control in DDMS to work in any locale not using '.' as adecimal point.

SDK Tools, Revision 6(May 2010)

If you are developing in Eclipse with ADT, note that SDK Tools r6 isdesigned for use with ADT 0.9.7 and later. After installing SDK Tools r6, wehighly recommend updating your ADT Plugin to 0.9.7.

The SDK Tools now support the use of library projects duringdevelopment, a capability that lets you store shared Android applicationcode and resources in a separate development project. You can then reference thelibrary project from other Android projects and, at build time, the toolscompile the shared code and resources as part of the dependent applications.More information about this feature is available in the Creating and Managing Projects document.

If you are developing in Eclipse, ADTprovides the equivalent library project support.

SDK Tools, Revision 5(March 2010)

• If you are developing in Eclipse with ADT, note that SDK Tools r5 isdesigned for use with ADT 0.9.6 and later. After installing SDK Tools r5, wehighly recommend updating your ADT Plugin to 0.9.6.
