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.
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.
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. Content and code samples on this page are subject to the licenses described in the Content License.
Android Developers. Revisions The sections below provide notes about successive releases of the SDK Tools, as denoted by revision number. SDK Tools, Revision Added a comment to explain that. All avd , target , and device commands should work as before. See the new Android Emulator Release Notes.
This change is backward compatible with older Android Studio versions. Android Emulator bug fixes: Fixed a crash on async socket reconnect. Fixed a crash on Mac when glDeleteTextures is called after the corresponding context was destroyed. Android Emulator bug fixes: Fixed a crash in gles pipe when accessing a closed one. Fixed a rare crash if emulator is closed during location loading. Added new sdkmanager command line tool to view, install, update, and uninstall individual Android SDK packages.
New Android Emulator features and bug fixes: Fixed -gpu guest issue Added support for WebP image decoding. Added support for ETC2 texture decompression.
Added simulated vertical swipes for scrolling through vertical menus with a mouse wheel. General Notes: To improve the security of the Android Emulator and to address a reported security vulnerability, the Android Emulator Console now requires authentication before you can enter commands.
Added SMP support to take advantage of host multi-core architecture when emulating Android 6. Also with SMP support, you can test apps that specifically target multi-core Android devices. See speed improvements up to five times faster than using a physical device. Extended UI controls and a floating toolbar provide easy access to features previously available only through the command line, such as taking screen captures, adjusting the battery level, rotating the screen, and managing virtual calls.
Dynamically resize the emulator by dragging a corner or zoom into the emulator window. Simulate multi-touch input. The Android Emulator works best with Android Studio 2. To find out more about what's included in the newest version of the official Android IDE, read the release notes. Read the documentation to find out more about using the Android Emulator.
SDK Platform-tools, Revision General Notes: Fixed a problem where the emulator title bar was hidden off screen. Issue Enabled the emulator to resize the user data partition by including e2fsprogs binaries. General Notes: Updated the emulator so it can display an upgrade notification when a new version is available. Added the ability for the emulator to send basic crash reports. You must opt-in through Android Studio preferences to enable crash report transmission.
General Notes: Added support for Android 6. Emulator: Improved emulator performance on multi-core Windows desktops. Added support for emulators with dpi and dpi screen resolutions.
Improved support for GLES 2. Fixed several issues with GPU emulation support. Added support for setting the storage size on emulators using Android 4. Issue Fixed problem with sending long SMS messages between emulators. Issue Fixed issue with emulator getting incorrect time from location objects. Issue Added handling for unusual characters in paths and file names when starting emulators. Fixed the emulator boot problem on Mac OS X General Notes: Fixed several minor emulator issues.
Fixed memory leaks in emulator system. General Notes: Fixed Java detection issue on bit Windows systems. General Notes: Added support for Android Studio 1. If you haven't already, update your ADT Plugin to General Notes: Fixed Windows bit compilation issue.
General Notes: Added ProGuard. Added the proguard-android. Renamed the lombok-ast General Notes: Added the Android Wear tools and system images.
General Notes: Fixed an issue with the x86 emulator that caused Google Maps to crash. Issue Fixed minor OpenGL issues. Issue Fixed a problem with Nexus 5 Android virtual devices created from the command line where the SD card file system was read-only. Issue Fixed a problem with virtual devices created using ADT Fixed a problem with the command line tools when creating virtual devices.
Issue Fixed a problem with the command line lint script. Known Issues: When you create an Android virtual device using the Nexus 5 device definition, you must enable the Use Host GPU option, otherwise the virtual device will not start. Added support for Java 7 language features like multi-catch, try-with-resources, and the diamond operator.
These features require version 19 or higher of the Build Tools. Try-with-resources requires minSdkVersion 19; the rest of the new language features require minSdkVersion 8 or higher.
Added new lint checks: Security: Look for code potentially affected by a SecureRandom vulnerability. Check that calls to checkPermission use the return value. Check that production builds do not use mock location providers.
Look for manifest values that are overwritten by values from Gradle build scripts. Fixed a number of minor issues in the SDK and build system. Emulator: Fixed a problem with the emulator shutting down immediately for Android 1. Issue Fixed a problem with port numbers longer than four digits.
Issue Fixed a problem with paths or arguments that contain spaces on Windows platforms. Issue Fixed a problem with long path values on Windows platforms. Issue Fixed a problem with the -snapshot-list command line option on bit systems.
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. SDK Manager Improved caching to reduce downloading of repository definitions. 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. Bug fixes: Fixed an issue that prevented some developers from running the emulator with GPU acceleration.
General notes: Updated the SdkController app to encapsulate both sensor and multitouch emulation functionality. General notes: Emulator Added support for hardware accelerated graphics rendering.
Added experimental support for multi-touch input by enabing the emulator to receive touch input from a USB-tethered physical Android device. 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. 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. 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.
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. You can use the new TargetApi annotation to suppress warnings when the code is wrapped in a system version condition. General notes: Added Lint tools to detect common errors in Android projects. Bug fixes: Snapshots now work for Android 4. Fixed several small issues for the build file.
Issue , Issue , Issue , Issue Bug fixes: Fixed emulator crash on Linux due to improper webcam detection Issue Fixed emulator issue when using the -wipe-data argument. Fixed ant test Issue Fixed android update project Issue Fixed issue with MonkeyRunner Issue General notes: Added webcam support to Android 4. Webcam support is for Windows and Linux only.
Mac support will come in a later release. Changed default. Any existing projects that you build with Ant must be updated with the android update project command. Changed Ant build. 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.
General notes: Fix compilation issue in Ant dex step when paths have spaces. Fix issue in emulator installation when paths have spaces. Fix issue when AVD paths have spaces. Fix rendering issue when using emulator scaling see more. General notes: Miscellaneous emulator changes to support Android 3.
General notes: The default ProGuard configuration, proguard. The default encoding for the javac Ant task is now UTF For details on the improvements, see the Android Tools Project Site.
