Android Studio Release Notes

Android Studio is the official IDE for Android development, and includes everything you need to develop Android apps in a single download. Download Android Studio here and get started by reading Meet Android Studio.

Periodic updates are pushed to Android Studio without requiring you to update your Android project. To manually check for updates, select Help > Check for update (on Mac, select Android Studio > Check for updates).

The sections below provide notes about successive releases of Android Studio, as denoted by revision number.

Android Studio v2.3.0 (March 2017)

Android Studio 2.3.0 is primarily a bug fix and stability release, but it also includes a number of new features.

Android Studio v2.3.3 (June 2017)

This is a minor update to add support for Android O (API level 26).

Android Studio v2.3.2 (April 2017)

This is a minor update to Android Studio 2.3 for the following changes:

  • AVD Manager updates to support Google Play in system images.
  • Bug fixes for NDK builds when using R14+ of the NDK.

Also see corresponding updates for Android Emulator 26.0.3.

Android Studio v2.3.1 (April 2017)

This is a minor update to Android Studio 2.3 that fixes an issue where some physical Android devices did not work properly with Instant Run (see Issue #235879).

New

Changes

This release also includes a number of bug fixes. See all bug fixes in 2.3.0.

Known issue: Some device manufacturers block apps from automatically launching after being installed on the device. When deploying your app to a physical device using Android Studio 2.3, this restriction breaks the intended behavior of Instant Run and causes the following error output: Error: Not found; no service started. To avoid this issue, either use the emulator or enable automatic launching for your app in your device's settings. The proceedure for doing this is different for each device, so check the instructions provided by the manufacturer. For example, some affected Asus devices need to whitelist apps using the Auto-start Manager. To learn more about this issue, see Issue #235879.

Android Studio v2.2.0 (September 2016)

Android Studio v2.2.3 (December 2016)

This is a minor update to Android Studio 2.2. It includes a bug fixes focused around gradle, the core IDE, and lint.

Highlighted build changes:

  • ProGuard version rollback. Due to a correctness issue discovered in ProGuard 5.3.1, we have rolled back to ProGuard 5.2.1. We have worked with the ProGuard team on getting a fix quickly, and we expect to roll forward to ProGuard 5.3.2 in Android Studio 2.3 Canary 3.
  • Bug fix for aaptOptions IgnoreAssetsPattern not working properly (issue 224167)
  • Bug fix for Gradle autodownload for Constraint Layout library (issue 212128)
  • Bug fix for a JDK8/Kotlin compiler + dx issue (issue 227729)

See all bug fixes in 2.2.3.

Android Studio v2.2.2 (October 2016)

This is a minor update to Android Studio 2.2. It includes a number of small changes and bug fixes, including:

  • When reporting Instant Run issues through the IDE, the report now also includes logcat output for InstantRun events. To help us improve Instant Run, please enable extra logging and report any issues.
  • A number of small bug fixes for Gradle.
  • A fix for problems with generating multiple APKs.

Android Studio v2.2.1 (October 2016)

This is a minor update to Android Studio 2.2. It includes several bug fixes and a new feature to enable extra logging to help us troubleshoot Instant Run issues—to help us improve Instant Run, please enable extra logging and report any issues.

Changes

Android Studio v2.1.0 (April 2016)

The primary changes in this update provide support for development with the Android N Preview.

Android Studio v2.1.3 (August 2016)

This update adds compatibility with Gradle 2.14.1, which includes performance improvements, new features, and an important security fix. For more details, see the Gradle release notes.

By default, new projects in Android Studio 2.1.3 use Gradle 2.14.1. For existing projects, the IDE prompts you to upgrade to Gradle 2.14.1 and Android plugin for Gradle 2.1.3, which is required when using Gradle 2.14.1 and higher.

Android Studio v2.1.2 (June 2016)

This update includes a number of small changes and bug fixes:

  • Instant Run updates and bug fixes.
  • Improvements to LLDB performance and crash notifications.
  • Fixed a regression in the Android Studio 2.1.1 security update that caused git rebase to fail.

Android Studio v2.1.1 (May 2016)

Security release update.

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 jackOptions property in your build.gradle file.

Other than the changes to support the N Preview, Android Studio 2.1 includes minor bug fixes and the following enhancements:

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 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.xml file. 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 lint tool 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.
  • Added support for more VectorDrawable elements to Vector Asset Studio for backward-compatibility. Vector Asset Studio can use these elements to convert vector drawables into PNG raster images to use with Android 4.4 (API level 20) and lower.

For example, for Android TV, it can report and provide a quick fix for permissions, unsupported hardware, uses-feature element, and missing banner issues. For Android Auto, it can validate the correct usage in the descriptor file referred from your AndroidManifest.xml file, report if there isn't an intent filter for the MediaBrowserService class, and identify certain voice actions issues.
  • Added new lint checks for insecure broadcast receivers, SSLCertificateSocketFactory and HostnameVerifier class uses, and File.setReadable() and File.setWritable() calls. It also detects invalid manifest resource lookups, especially for resources that vary by configuration.
  • Fixed a number of stability issues.

Android Studio v1.4.1 (October 2015)

Fixes and enhancements:

  • Fixed a Gradle model caching issue that could lead to excessive Gradle syncing when the IDE was restarted.
  • Fixed a native debugging deadlock issue.

Android Studio v0.3.2 (Oct 2013)

Android Studio v0.2.x (July 2013)

  • Merged in the latest IntelliJ codebase changes. Includes fixes for issues reported by Studio users such as tweaks to Linux font sizes and font rendering.
  • Android Gradle plug-in updated to 0.5.0.

    Caution: This new version is not backwards compatible. When opening a project that uses an older version of the plug-in, Studio will show an error stating Gradle <project_name> project refresh failed.

    The updated Gradle plug-in includes the following changes:

    • Fixed IDE model to contain the output file even if it's customized through the DSL. Also fixed the DSL to get/set the output file on the variant object so that it's not necessary to use variant.packageApplication or variant.zipAlign
    • Fixed dependency resolution so that we resolved the combination of (default config, build types, flavor(s)) together instead of separately.
    • Fixed dependency for tests of library project to properly include all the dependencies of the library itself.
    • Fixed case where two dependencies have the same leaf name.
    • Fixed issue where Proguard rules file cannot be applied on flavors.

    All Gradle plugin release notes are available are here: http://tools.android.com/tech-docs/new-build-system.

  • Gradle errors from aapt no longer point to merged output files in the build/ folder, they point back to the real source locations.
  • Parallel Builds. It's now possible to use Gradle's parallel builds. Please be aware that parallel builds are in "incubation" (see Gradle's documentation.) This feature is off by default. To enable it, go to Preferences > Compiler and check the box Compile independent modules in parallel.
  • Further work on the new resource repository used for layout rendering, resource folding in the editor, and more:
    • Basic support for .aar library dependencies (e.g. using a library without a local copy of the sources). Still not working for resource XML validation and navigation in source editors.
    • Cycle detection in resource references.
    • Quick Documentation (F1), which can show all translations of the string under the caret, will now also show all resource overlays from the various Gradle flavors and build types, as well as libraries. They are listed in reverse resource overlay order, with strikethrough on the versions of the string that are masked.
    • Fixes to handle updating the merged resources when the set of module dependencies change.
    • XML rendering fixes to properly handle character entity declarations and XML and unicode escapes.
  • Save screenshot support for the layout preview and layout editor windows.
  • Template bug fixes.
  • Lint bug fixes.
  • Various fixes for crash reports. Thank you, and keep filing crash reports!

Android Studio v0.1.x (May 2013)

  • Various bug fixes, including a fix for a common Windows installation issue.
