    set dex.force.jumbo=true

  • 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.

• Build System
  • Added automatic merging of library project manifest files into the including project's manifest. Enable this feature with the manifestmerger.enabled property.
  • Added automatic ProGuard support for the aapt -G flag. This change causes the build system to generate a temporary ProGuard keep-rules file containing classes that are referenced from XML files (such as custom views) and pass this to ProGuard at shrink time. This can 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 the default 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 which disables them.
• SDK Manager

If you are developing in Eclipse with ADT, note that this version of SDK Tools is designed for use with ADT 10.0.0 and later. After installing SDK Tools r10, we highly recommend updating your ADT Plugin to 10.0.0.

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

General notes:

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

Dependencies:

If you are developing in Eclipse with ADT, note that this version of SDK Tools 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.

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

Upgrading to SDK Tools r9:

If you are upgrading to SDK Tools r9 from SDK Tools r7 or earlier, the default installed location for the adb tool has changed from <SDK>/tools/adb to <SDK>/platform-tools/adb. 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 adb executable from the new location to the old is not recommended, since subsequent updates to the SDK Tools will delete the file.

General notes:

• 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 can enable snapshots for the system state. The emulator will then restore to the state when it last closed almost instantly. Note: The snapshot feature is still under active development 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 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.

Dependencies:

If you are developing in Eclipse with ADT, note that this version of SDK Tools is designed for use with ADT 8.0.0 and later. After installing SDK Tools r8, we highly recommend updating your ADT Plugin to 8.0.0.

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

Also note that SDK Tools r8 requires a new SDK component called Platform-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 build tools such as adb, aapt, aidl, and dx. To download the Platform-tools component, use the Android SDK Manager, as described in Exploring the SDK

Upgrading from SDK Tools r7:

If you are upgrading to SDK Tools r8 from an earlier version, note that the the default installed location for the adb tool has changed from <SDK>/tools/adb to <SDK>/platform-tools/adb. 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 adb executable from the new location to the old is not recommended, since subsequent updates to the SDK Tools will delete the file.

General notes:

• All SDK platforms now support Library Projects.
• Support for a true debug build. Developers no longer need to add the android:debuggable attribute to the <application> tag in the manifest — the build tools add the attribute automatically. In Eclipse/ADT, all incremental builds are assumed to be debug builds, so the tools insert android:debuggable="true". When exporting a signed release build, the tools do not add the attribute. In Ant, a ant debug command automatically inserts the android:debuggable="true" attribute, while ant release does not. If android:debuggable="true" is manually set, then ant release will actually do a debug build, rather than a release build.
• Automatic ProGuard support in release builds. Developers generate a ProGuard configuration file using the android tool — the build tools then automatically run ProGuard against the project sources during the build. For more information, see the ProGuard documentation.
• 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.

Dependencies:

If you are developing in Eclipse with ADT, note that this version of SDK Tools is designed for use with ADT 0.9.8 and later. After installing SDK Tools r7, we highly recommend updating your ADT Plugin to 0.9.8.

General notes:

• 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 the normal tasks: -pre-build, -pre-compile, and -post-compile.
• Adds support for "headless" SDK update. See android -h update sdk for more information.
• Fixes location control in DDMS to work in any locale not using '.' as a decimal point.

Dependencies:

If you are developing in Eclipse with ADT, note that this version of SDK Tools is designed for use with ADT 0.9.7 and later. After installing SDK Tools r6, we highly recommend updating your ADT Plugin to 0.9.7.

Library projects:

The SDK Tools now support the use of library projects during development, a capability that lets you store shared Android application code and resources in a separate development project. You can then reference the library project from other Android projects and, at build time, the tools compile 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, ADT provides the equivalent library project support.

Dependencies:

• If you are developing in Eclipse with ADT, note that this version of SDK Tools is designed for use with ADT 0.9.6 and later. After installing SDK Tools r5, we highly recommend updating your ADT Plugin to 0.9.6.
• For Mac OS platforms, OS X 10.4.x (Tiger) is no longer officially supported.

SDK and AVD Manager:

• Fixes SSL download for the standalone version of the SDK Updater.
• Fixes issue with 64-bit JVM on Windows.
• Adds support for platform samples components.
• Improves support for dependency between components.
• AVDs now sorted by API level.
• The AVD creation dialog now enforces a minimum SD card size of 9MB.
• Prevents deletion of running AVDs.
• Settings are now automatically saved, no need to click "Apply".

Emulator:

• Emulator now requires SD card to be 9MB or more.

Layoutopt:

• Fixes layoutopt.bat to execute correctly on Windows.

Dependencies:

This version of SDK Tools is compatible with ADT 0.9.5 and later, but not compatible with earlier versions. If you are developing in Eclipse with ADT, you must update your ADT plugin to version 0.9.5 or higher if you install SDK Tools r4 in your SDK.

General notes:

• Launcher script now forces GDK_NATIVE_WINDOW=true (linux only), to fix a compatibility issue between GTK and SWT.

Android SDK and AVD Manager:

• AVD Launch dialog now shows scale value.
• Fixes potential NPE in SDK Manager on AVD launch, for older AVD with no skin name specified.
• Fixes XML validation issue in on older Java versions.
• No longer forces the use of Java 1.5 on Mac OS X.

Emulator:

• No longer limits the size of the system partition.

Ant build tools:

• .apk packaging now properly ignores vi swap files as well as hidden files.

Dependencies:

This version of SDK Tools is compatible with ADT 0.9.4 and later, but not compatible with earlier versions. If you are developing in Eclipse with ADT, you must update your ADT plugin to version 0.9.4 or higher if you install SDK Tools r3 in your SDK.

Android tool:

• Adds new android create test-project and android update test-project commands to allow for greater flexibility in the location of the main and test projects.

DDMS:

• Adds a button to dump HPROF file for running applications (app must be able to write to the sdcard).
• Button to start/stop profiling of a running application (app must be able to write to the sdcard). Upon stop, Traceview will automatically be launched to display the trace.
• Fixed DDMS, Traceview, and the AVD Mananger/SDK Updater to run on Mac OS X 10.6.
• Fixed screenshot support for devices running 32-bit framebuffer.

Android SDK and AVD Manager:

• Provides a new UI that lets you set options for controlling the emulator skin, screen size/density, and scale factor used when launching an AVD.
• Provides improved AVD creation UI, which lets you customize the hardware properties of your AVDs.
• Now enforces dependencies between platforms and tools components, and between SDK add-ons and platforms.

Layoutopt, a new tool for optimizing layouts:

The SDK Tools r3 package includes layoutopt, a new command-line tool that helps you optimize your layout hierarchies. When run against your layout files, the tool analyzes their hierarchies and notifies you of inefficiencies and other potential issues. The tool also provides simple solutions for the issues it finds. For usage, see layoutopt.
