Android Studio 3.1 Canary 1 is now available in the Canary and Dev channels.

If you already have an Android Studio build on the Canary or Dev channel, you can get the update by clicking Help > Check for Update (or Android Studio > Check for Updates on Mac). Otherwise, you can download it here.

This update includes bug fixes and improvements, such as the following:

• New DEX compiler: by default, Android Studio now uses a new DEX compiler called D8, which was announced on the Android Developers Blog.
• Sample native processes with CPU Profiler: the CPU Profiler now includes a default configuration to record sampled traces of your app's native threads. You can use this configuration by deploying your app to a device running Android 8.0 (API level 26) or higher and then selecting Sampled (Native) from the CPU profiler's recording configurations dropdown menu. After that, record and inspect a trace as you normally would.
• Updates to Lint: When you run lint from the command line, lint now also analyzes your Kotlin classes. For each project that you would like to run lint on, make sure to include Google's Maven repository in the top-level build.gradle file, as shown below:

allprojects {
    repositories {
        // The order in which you list these repositories matter.
        google()
        jcenter()
    }
}

• New Layout Editor action to convert views from one type to another. From the component tree pane in the Layout Editor, right-click on a component and select Convert view. In the dialog that appears (shown below), select a suggested view type and click Apply. If the IDE doesn’t suggest the type of view you want, search for it using the text field near the top of the dialog.

If you've set your Android Studio update channel to canary, the SDK Manager should now show an update to receive version 26.2.0 of the Android Emulator. This is the first release to include the new Quick Boot feature, which makes the Android Emulator start up much faster based on a snapshot of your previous AVD instance.

If you've set your Android Studio update channel to canary, the SDK Manager should now show an update to receive version 26.2.0 of the Android Emulator. This is the first release to include the new Quick Boot feature, which makes the Android Emulator start up much faster based on a snapshot of your previous AVD instance.

Quick Boot is enabled by default for all AVDs. Although the first time you start an AVD it must perform a cold boot (just like powering on a device), all subsequent starts are fast and the system is restored to the state at which you closed the emulator (similar to waking a device). Learn more about Quick Boot here.

Other changes in this release include:

• Mac OpenGL ES 3 support (for supported system images: API 24+ Google APIs x86).
• GLESv3-capable AVDs and host now use OpenGL core profile. This can help fix Pixel Launcher crashes and other host GPU driver issues. To force enable, add the line GLESDynamicVersion = on inside ~/.android/advancedFeatures.ini (create this file if it doesn't exist). Then start the emulator, open the Extended controls window, select Settings > Advanced, and set the OpenGL ES renderer to Desktop native OpenGL.

dependencies {
  compile 'com.android.support.constraint:constraint-layout:1.1.0-beta2'
}

Changes:

• Many bug fixes (mostly in complex behavior in chains, match constraint, min/max/ratio/percent)
• Redesign of the constraint optimizer, performances are improved
• Change in behavior with 0dp in packed chain (0dp elements will spread)
• Added a new attribute to enforce constraints on wrap_content if needed (previously, wrap_content was considered a fixed dimension not subject to the constraints):
• app:layout_constrainedWidth=”true|false”
• app:layout_constrainedHeight=”true|false”
• Note that the setting to have a match_constraint set to wrap behavior has been deprecated, instead you should use the above layout_constrainedWidth/Height attribute along with width=wrap_content.
