  • 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.

  • General Notes:
  • Build System
  • Added a flag that sets jumbo mode for DEX files, which allows a larger number of strings in the DEX files.
  • 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.
  • Added jobb tool for creating and encrypting APK Expansion Files.
  • Improved the Android JUnit test runner to allow a test to be run on all connected devices simultaneously.
  • Bug fixes:
  • Fixed manifest merger to properly adapt library classes in the merged manifest.

New in Android SDK Release 20.0.3 (Nov 14, 2012)

  • Dependencies:
  • 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.
  • Bug fixes:
  • Fixed problem with cached download lists in SDK Manager.

New in Android SDK Release 20.0.1 (Jul 19, 2012)

  • Dependencies:
  • Android SDK Platform-tools revision 12 or later.
  • If you are developing in Eclipse with ADT, note that the SDK Tools r20.0.1 is designed for use with ADT 20.0.1 and later. If you haven't already, update your ADT Plugin to 20.0.1.
  • If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.
  • Bug fixes:

  • General notes:
  • Added new Device Monitor application, grouping Android debugging tools into a single application, including ddms, traceview, hierarchyviewer and Tracer for GLES.
  • Added new System Trace new tool for tracing Android system activity. This tool allow you to capture a slice of system activity, plus additional information tagged from the Settings > Developer Options > Monitoring: Enable traces or with specific calls added to your application code.
  • 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
  • Improved caching to reduce downloading of repository definitions.
  • Added Tools > Manage Add-on Sites option to allow deactivation of third-party sites for improved performance (e.g., if one or more sites are temporarily slow to load.)
  • 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.

New in Android SDK Release 19 (Jun 27, 2012)

  • Dependencies:
  • Android SDK Platform-tools revision 9 or later.
  • If you are developing in Eclipse with ADT, note that the SDK Tools r19 is designed for use with ADT 18.0.0 and later. If you haven't already, we highly recommend updating your ADT Plugin to 18.0.0.
  • If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.
  • Bug fixes:
  • Fixed an issue that prevented some developers from running the emulator with GPU acceleration.

New in Android SDK Release 18 (Apr 10, 2012)

  • Dependencies:
  • Android SDK Platform-tools revision 9 or later.
  • If you are developing in Eclipse with ADT, note that the SDK Tools r18 is designed for use with ADT 18.0.0 and later. If you haven't already, we highly recommend updating your ADT Plugin to 18.0.0.
  • If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.
  • General notes:
  • Updated the SdkController app to encapsulate both sensor and multitouch emulation functionality.
  • Bug fixes:
  • Fixed Ant issues where some jar libraries in the libs/ folder are not picked up in some cases.

New in Android SDK Release 17 (Mar 22, 2012)

  • Emulator:
  • Added support for hardware accelerated graphics rendering. This feature requires an API Level 15, Revision 3 or later system image.
  • Added experimental support for multi-touch input by enabing the emulator to receive touch input from a USB-tethered physical Android device.
  • Added viewing of live detailed network usage of an app in DDMS.
  • ProGuard:
  • Updated the bundled ProGuard tool to version 4.7. In addition to many new features, this update fixes the Conversion to Dalvik format failed with error 1 error some users have experienced.
  • Updated the default proguard.cfg file with better default flags for Android.
  • Split the ProGuard configuration file has been in half, with project specific flags kept in project and the generic Android flags distributed (and updated) with the tools themselves.
  • Build:
  • Added a feature that allows you to run some code only in debug mode. Builds now generate a class called BuildConfig containing a DEBUG constant that is automatically set according to your build type. You can check the (BuildConfig.DEBUG) constant in your code to run debug-only functions.
  • Fixed issue when a project and its libraries include the same jar file in their libs folder.
  • Added support for custom views with custom attributes in libraries. Layouts using custom attributes must use the namespace URI http://schemas.android.com/apk/res-auto instead of the URI that includes the app package name. This URI is replaced with the app specific one at build time.
  • Lint:
  • Updated Lint to check Android application code. Lint rules which previously 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 @SuppressLint annotation, and in XML files with the new tools: namespace and ignore attribute.
  • 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 @TargetApi annotation to suppress warnings when the code is wrapped in a system version condition.
  • Added over 20 new Lint rules, including checks for performance, XML layouts, manifest and file handling.

  • Dependencies:
  • Android SDK Platform-tools revision 9 or later.
  • If you are developing in Eclipse with ADT, note that the SDK Tools r16 is designed for use with ADT 16.0.0 and later. If you haven't already, we highly recommend updating your ADT Plugin to 16.0.0.
  • If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.
  • General notes:
  • Added Lint tools to detect common errors in Android projects.
  • Added sensor emulation support, which allows the emulator to read sensor data from a physical Android device.
  • Bug fixes:
  • Snapshots now work for Android 4.0 system images.
  • Fixed several small issues for the build file

New in Android SDK Release 15 (Oct 28, 2011)

  • Dependencies:
  • Android SDK Platform-tools revision 9 or later.

  • General notes:
  • Added webcam support to Android 4.0 or later platforms to emulate rear-facing cameras when one webcam is present, and to emulate both rear-facing and front-facing cameras when two webcams are present. Webcam suport is for Windows and Linux only. Mac support will come in a later release.
  • Changed default.properties to project.properties and build.properties to ant.properties. Any existing projects that you build with Ant must be updated with the android update project command.
  • Changed Ant build.xml file to support improvements to the build system and added and modified Ant commands to support these changes. For a list of Ant commands, see the Ant Command Reference.
  • Changed how library projects are built.
  • Improved incremental builds, so that resource compilation runs less frequently. Builds no longer run when you edit strings or layouts (unless you add a new id) and no longer run once for each library project.
  • Introduced a "PNG crunch cache" that only runs on modified PNG files, instead of crunching all existing PNG files, all the time.
  • Revamped the SDK Manager UI

New in Android SDK Release 13 (Sep 23, 2011)

  • Dependencies:
  • If you are developing in Eclipse with ADT, note that the SDK Tools r13 is designed for use with ADT 12.0.0 and later. If you haven't already, we highly recommend updating your ADT Plugin to 12.0.0.

New in Android SDK Release 11 (May 11, 2011)

  • Dependencies:
  • If you are developing in Eclipse with ADT, note that the SDK Tools r11 is designed for use with ADT 10.0.1 and later. If you haven't already, we highly recommend updating your ADT Plugin to 10.0.1.
  • If you are developing outside Eclipse, you must have Apache Ant 1.8 or later.
  • General notes:
  • Miscellaneous emulator changes to support Android 3.1.

New in Android SDK Release 10 (Feb 23, 2011)

  • Dependencies:
  • If you are developing in Eclipse with ADT, note that the SDK Tools r10 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

New in Android SDK Release 09 (Jan 27, 2011)

  • Dependencies:
  • 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.
  • 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 /tools/adb to /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.
  • 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.
  • 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.

New in Android SDK Release 08 (Dec 6, 2010)

  • Dependencies:
  • If you are developing in Eclipse with ADT, note that SDK Tools r8 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.
  • 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 Adding SDK Components
  • 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 /tools/adb to /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 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.

New in Android SDK Release 07 (Dec 6, 2010)

  • Dependencies:
  • If you are developing in Eclipse with ADT, note that SDK Tools r7 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.

New in Android SDK Release 06 (May 21, 2010)

  • Dependencies:
  • If you are developing in Eclipse with ADT, note that SDK Tools r6 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 Developing in Other IDEs document.
  • If you are developing in Eclipse, ADT 0.9.7 provides the equivalent library project support.

New in Android SDK Release 05 (May 13, 2010)

  • Dependencies:
  • If you are developing in Eclipse with ADT, note that SDK Tools r5 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.
  • 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.

New in Android SDK Release 04 (Dec 4, 2009)

  • This release includes minor API changes, bug fixes and framework behavioral changes. For information on changes and fixes, see the Framework API section.
  • For developers, the Android 2.0.1 platform is available as a downloadable component for the Android SDK. The downloadable platform includes a fully compliant Android library and system image, as well as a set of emulator skins, sample applications, and more. The downloadable platform includes no external libraries

New in Android SDK 2.0 Release 1 (Oct 28, 2009)

  • The SDK downloadable package includes only the latest version of the Android SDK Tools.
  • Once you've installed the SDK, you now use the Android SDK and AVD Manager to download all of the SDK components that you need, such as Android platforms, SDK add-ons, tools, and documentation.
  • The new approach is modular — you can install only the components you need and update any or all components without affecting other parts of your development environment.
  • In short, once you've installed the new SDK, you will not need to download an SDK package again. Instead, you will use the Android SDK and AVD Manager to keep your development environment up-to-date.

New in Android SDK 1.6 Release 1 (Sep 16, 2009)

  • Emulator support for multiple screen sizes/densities, including new skins.
  • Android SDK and AVD Manager, a graphical UI to let you manage your SDK and AVD environments more easily. The tool lets you create and manage your Android Virtual Devices and download new SDK packages (such as platform versions and add-ons) into your environment.
  • Improved support for test packages in New Project Wizard

New in Android SDK 1.5 R3 (Jul 17, 2009)

  • The SDK includes a new version of the Google APIs add-on. The add-on provides an updated com.google.android.maps external library that fixes compile errors related to certain classes such as GeoPoint.
  • The SDK add-on architecture now lets device manufacturers specify a USB Vendor ID in their add-ons.
  • The android tool provides a new command that scans SDK add-ons for their USB Vendor IDs and makes them available to adb (OS X and Linux versions of the SDK only). The command is android update adb. On Windows versions of the SDK, a custom USB driver is included that supports the "Google" and "HTC" Vendor IDs, which allow adb to recognize G1 and HTC Magic devices. For other devices, contact the device manufacturer to obtain a USB driver, especially if you have an SDK add-on that defines a new USB Vendor ID.
  • The telephony, sensor, and geo fix issues in the emulator are now fixed.
  • When you use adb to uninstall an upgraded application, the Android system now properly restores any permissions that had already been granted to the previous (downgrade) version of the application

New in Android SDK 1.5 R2 (Jun 26, 2009)

  • Provides an updated Android 1.5 system image that includes a security patch

New in Android SDK 1.5 R1 (Apr 28, 2009)

  • Multiple versions of the Android platform are included (Android 1.1, Android 1.5). The tools are updated to let you deploy your application on any platform in the SDK, which helps you ensure forward-compitility and, if applicable, backward-compatibility.
  • Introduces Android Virtual Devices — (AVD) configurations of options that you run in the emulator to better model actual devices. Each AVD gets its own dedicated storage area, making it much easier to work with multiple emulators that are running concurrently.
  • Support for SDK add-ons, which extend the Android SDK to give you access to one or more external Android libraries and/or a customized (but compliant) system image that can run in the emulator.
  • The new Eclipse ADT plugin (version 0.9.0) offers new Wizards to let you create projects targetted for specific Android configurations, generate XML resources (such as layouts, animations, and menus), generate alternate layouts, and export and sign your application for publishing.
  • Improved JUnit support in ADT
  • Easier profiling of performance
  • Easier management of localized applications. You can now include or exclude locale resources when building your APK from a single Android project.
  • A new tool called "android" replaces the activitycreator script.

New in Android SDK 1.0 (Sep 29, 2008)

  • Emulator now saves the user image in /SDK1.0/
  • Fixed EsounD-related freezes on Linux.
  • Fixed the documentation in -help-audio. '-audio list' doesn't work, one needs to call -help-audio-out and -help-audio-in to get the list of valid audio backends.
  • Fixed scrollwheel Dpad emulation in rotated mode. before that, using the scroll-wheel would always generated Dpad Up/Down events, even when in landscape mode.
  • Several Obsolete command options were removed.
  • Setting the network speed through the console or the -netspeed option will properly modify the connectivity icon on the device.
  • Setting the GSM voice registration state to 'roaming' in the console will properly modify the voice icon on the device
  • If you are developing in Eclipse/ADT and want to add JUnit test classes, you can do so. However, you need to set up a custom JUnit configuration before your tests will run properly. For detailed information about how to set up the JUnit configuration, see the troubleshooting topic Running a Junit test class in Eclipse.
  • It is not possible to send MMS messages between emulator instances.
  • In some cases, you may encounter problems when using the browser on an emulator started with the command-line option -http-proxy.
  • We regret to inform developers that Android 1.0 will not include support for dot-matrix printers.
  • On the OSX platform, if you manually remove the ~/.android directory using rm -rf ~/.android, then try to run the emulator, it crashes. This happens because the emulator fails to create a new .android directory before attempting to create the child SDK1.0 directory. To work around this issue, manually create a new .android directory using mkdir ~/.android, then run the emulator. The emulator creates the SDK1.0 directory and starts normally.
  • The final set of Intent patterns honored by Android 1.0 has not yet been fully documented. Documentation will be provided in future releases.
  • In ADT Editor, you can add at most ten new resource values at a time, in a given res/values/*.xml, using the form in the Android Resources pane. If you add more than ten, the Android Resources pane will not display the attributes fields for the additional resource entries. To work around this problem, you can close the file in the editor and open it again, or you can edit the resource entries in the XML text mode.
  • The emulator's battery-control commands (power ) are not working in this release.
