Android Studio v2.1.1 (May 2016)
Security release update.
Android Studio v2.1.0 (April 2016)
The primary changes in this update provide support for development with the Android N Preview.
The Android N platform adds support for Java 8 language features, which require a new experimental compiler called Jack. The latest version of Jack is currently supported only in Android Studio 2.1. So if you want to use Java 8 language features, you need to use Android Studio 2.1 to build your app.
Note: Instant Run is disabled when you enable the Jack compiler because they currently are not compatible.
Although Android Studio 2.1 is now stable, the Jack compiler is still
experimental and you must enable it with the
property in your
Other than the changes to support the N Preview, Android Studio 2.1 includes minor bug fixes and the following enhancements:
- The Java-aware C++ debugger is now enabled by default when you're using an N device or emulator and select Native debugger mode (in the Debugger tab for your run/debug configuration).
For other build enhancements, including incremental Java compilation and dexing-in-process,update your Android Plugin for Gradle to version 2.1.0.
Android Studio v2.0.0 (April 2016)
Note: If you are developing for the N Developer Preview, you should use Android Studio 2.1 Preview. Android Studio 2.0 does not support all the features required to target the N Preview. To learn more, read about how to properly set up your developer environment for the N Preview.
- Android Studio now deploys clean builds faster than ever before. Additionally, pushing incremental code changes to the emulator or a physical device is now almost instantaneous. Review your updates without redeploying a new debug build or, in many cases, without restarting the app.
- Instant Run supports pushing the following changes to a running app:
- Changes to the implementation of an existing instance method or static method
- Changes to an existing app resource
- Changes to structural code, such as a method signature or a static field (requires a target device running API level 21 or higher).
- Read the documentation to learn more about Instant
Note: Instant Run is supported only when you deploy the debug build variant, use Android Plugin for Gradle version 2.0.0 or higher, and configure your app's module-level
minSdkVersion 15or higher. For the best performance, configure your app for
minSdkVersion 21or higher.
New additions to Lint:
- Inspection of
@IntDefannotated integers to make sure all constants are handled. To quickly add any missing statements, use the the intention action drop-down menu and select Add Missing @IntDef Constants.
- Flags for incorrect attempts to use string interpolation to insert
version numbers in the
- Flags for anonymous classes that extend the
- Flags for native code in unsafe locations, such as the
asset/folders. This flag encourages storing native code in the
libs/folder, which is then securely packaged into the application’s
data/app-lib/folder at install time. AOSP: #169950
- Flags for unsafe calls to
System.load()calls. AOSP: #179980
- Find and remove any unused resources by selecting Refactor > Remove
Unused Resources from the menu bar. Unused resource detection now
supports resources only referenced by unused resources, references in raw
files such as
.htmlimage references, and
tools:discardattributes used by the Gradle resource shrinker, while considering inactive source sets (such as resources used in other build flavors) and properly handling static field imports.
- Checks that implicit API references are supported on all platforms
- Flags improper usage of
@Sizeinspections are now also checked for
intarrays and varargs.
- Optimized for Android Emulator 2.0, which is faster than ever before, supports a wider range of virtual devices, and features a drastically improved UI. To learn more about the new emulator, read the SDK Tools release notes.
- Improvements to the Android Virtual Device
- System images are now categorized under the following tabs: Recommended, x86, and Other.
- Under advanced settings, you can enable multi-core support and specify the number of cores the emulator can use.

on the emulator by selecting one of the following options:
- Hardware: use you computer's graphics card for faster rendering.
- Software: use software-based rendering.
- Auto: let the emulator decide the best option. This is the default setting.
- Improved AAPT packaging times by specifying deploy target before the app is built. This allows Android Studio to efficiently package only the resources required by the specified device.
- Added Cloud Test Lab integration to provide on-demand app testing with the convenience and scalability of a cloud service. Learn more about how you can use Cloud Test Lab with Android Studio.
- Added a preview of the new GPU Debugger. For graphics intensive applications, you can now visually step through your OpenGL ES code to optimize your app or game.

Android Studio v1.5.0 (November 2015)
Fixes and enhancements:
- Added new Memory Monitor analysis abilities to Android Monitor. When you view an HPROF file captured from this monitor, the display is now more helpful so you can more quickly locate problems, such as memory leaks. To use this monitor, click Android Monitor at the bottom of the main window. In Android Monitor, click the Memory tab. While the monitor is running, click the Dump Java Heap icon, and then click Captures in the main window and double-click the file to view it. Click Capture Analysis on the right. (The Android Device Monitor can't be running at the same time as Android Monitor.)
- Added new deep link and app link support. The Code Editor can automatically create an
intent filter for deep linking in the
AndroidManifest.xmlfile. It can also generate code to help you integrate with the App Indexing API in an activity in a Java file. A deep link testing feature helps you verify that a specified deep link can launch an app. In the General tab of the Run/Debug Configurations dialog, you can specify deep link launch options. You can also test App Indexing API calls in an activity by using the Android Monitor logcat display. The Android
linttool now has warnings for certain issues involving deep links and the App Indexing API.
- Added the ability to use short names when code-completing custom views in the Code Editor.
