Fixes

Android Studio 2.4 Preview 5 includes updates from IntelliJ 2017.1. This is the latest stable release from JetBrains and will likely be the last major IntelliJ update in Android Studio 2.4.

We continue to close bugs as we work to a beta quality release.

Whats New Build

Java 8 language features support. This preview release introduces built-in support for Java 8 libraries and certain Java 8 language features. Jack is no longer required, and you should first disable Jack to use the improved Java 8 support built into the default toolchain. For more information see how to use Java 8 language features.

Deploy and Test

The Google Play store app is now included in Android 7.0 (API 24) emulator system images. You will need to create a new Android Virtual Devices and select a hardware device configuration compatible with the Google Play Store.

Note: Compatible devices are denoted by the new Play Store column Fixes

We continue to fix issues as they are reported, triaged, and prioritized by our development teams. Please continue to file feedback with reproducible steps as we work to reach a beta quality build.

Known Issues

After updating the Android plugin version, you need to stop the Gradle daemon to apply the update (Issue 267099). Otherwise, Gradle sync and builds fail with the following error: Could not initialize class com.android.ide.common.util.ReadWriteProcessLock, Failed to notify build listener, or java.lang.ExceptionInInitializerError.

To stop the daemon, you can either restart Android Studio, or enter the following command in the IDE's Terminal window: ./gradlew --stop. Gradle restarts the daemon for you the next time you sync or build your project.

Android Studio 2.4 Preview 1 is now Available

Tuesday, March 14, 2017

Code:

In Android Studio 2.4 Preview 1 we upgraded the base IDE from IntelliJ 2016.2 to 2017.1 EAP, which adds a number of new features in 2016.3 and 2017.1 -- including parameter hints, semantic highlighting, instant results in search, and much more.

Many new lint checks

Instant Run:

Instant Run Debug Issue 234401 should now be resolved. If a program is paused on breakpoint, app restarting is expected. But if the app is not paused on a breakpoint, it shouldn’t restart and hot swap should work when you only make a method implementation change.

Build:

Incremental dex’ing. Dex’ing is now done at a per class level. This allows for more incrementality and will result in faster incremental builds. You should also expect improved build speeds for applications using legacy multi-dex (minSdkVersion < 21).

Dependency resolution at execution time. In previous versions, dependency resolution occurs during Gradle configuration time. By moving dependency resolution to execution time, you should expect improved configuration times for large projects.

IDE:

Android Studio on the mac will now be called “Android Studio 2.4 Preview.app” to make it easier for you to run 2.3 stable with the new previews side by side.

Device File Explorer - Seamlessly view, modify and interact with device filesystems directly in Android Studio. This feature replaces device filesystem interactions previously accomplished through DDMS (Dalvik Debug Monitor Server)

Known Issues:

If you check for updates it will tell you there is a new version of Android Studio 2.4 Preview 1 (build 171.3804684). This is the same build you already have installed. Please don't try to download it again. We will have a fix included in Android Studio 2.4 Preview 2.

Mac builds may prompt you saying it can't be opened because it is from an unidentified developer. The zip appears to signed, but has issues. We will update it in Preview 2. If you want to try it in preview 1, please right click and select open.
