resource problems, graphic asset issues and manifest tags.
- Added new aapt feature to compile resources.
SDK Tools, Revision 21.0.1 (December 2012)
- Dependencies:
-
- Android SDK Platform-tools revision 16 or later.
- If you are developing in Eclipse with ADT, note that this version of SDK Tools 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.
- General Notes:
-
- 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
{@code project.properties} file: {@code 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 {@code 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:
renderscript.target = 17
Previously, the RenderScript compilation target was tied to the
{@code android:minSdkVersion} setting in the manifest.
(Issue 40487)

- 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.

the {@code project.properties} file of your project:
dex.force.jumbo=true
- Improved the build time by pre-dexing libraries (both JAR files and library
projects).
- Updated the build to generate {@code R} resource classes for library projects

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 {@link android.util.SparseArray} and
{@link android.os.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 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.

- Fixed memory leak in the emulator.
SDK Tools, Revision 20 (June 2012)
- Dependencies:
-
- Android SDK Platform-tools revision 12 or later.
- If you are developing in Eclipse with ADT, note that this version of SDK Tools is designed for
use with ADT 20.0.0 and later. If you haven't already, we highly recommend updating your
ADT Plugin to 20.0.0.

Apache Ant 1.8 or later.
- General notes:
-
- Added new Device Monitor application, grouping Android debugging tools into a
single application, including ddms, traceview, hierarchyviewer and Tracer for GLES. (more info)

application code.
- Build System
- Added automatic merging of library project manifest files into the including
project's manifest. Enable this feature with the {@code manifestmerger.enabled} property.
- Added automatic ProGuard support for the {@code aapt -G} flag. This change causes
the build system to generate a temporary ProGuard {@code 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: {@code
proguard-android-optimize.txt} which enables optimizations and {@code proguard-android.txt} which
disables 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.
- Added settings for the SDK Manager download cache (SDK Manager > Tools >
Options).
- Bug fixes:
-
- Build
- Fixed problem where test projects did not have access to the full classpath of tested
projects, including Library Projects and third-party jars.
- Fixed deployment logic so that applications with embedded tests can now be deployed
and tested like test applications, including code coverage information.
- Fixed Ant support for testing projects with libraries.

performed pattern based searches in the application code (such as the unused resource check) have
been rewritten to use the more accurate Java-style parse trees.
- Added support for checking library projects. This change means that rules such as
the unused resource check properly handle resources declared in a library project and referenced in
a downstream project.
- Added ability to suppress Lint warnings in Java code with the new
{@code @SuppressLint} annotation, and in XML files with the new tools: namespace and
ignore attribute. (more info)
- New Lint checks:
- Added check for Android API calls that require a version of Android higher than
the minimum supported version. You can use the new {@code @TargetApi} annotation
to suppress warnings when the code is wrapped in a system version condition.
(more info)
- Added over 20 new Lint rules, including checks for
performance,
XML layouts, manifest and file handling.

SDK Tools, Revision 10 (February 2011)
- Dependencies:
-
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
SDK Tools, Revision 9 (January 2011)
- 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 {@link android.preference.Preference}
- classes that extend {@link android.app.backup.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.
SDK Tools, Revision 8 (December 2010)
- 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.
SDK Tools, Revision 7 (September 2010)
- 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.
SDK Tools, Revision 6 (May 2010)
- 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.
SDK Tools, Revision 5 (March 2010)
- 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

- 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.

- 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:

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.
