Android Studio 3.2 Beta

Posted by Jamal Eason, Product Manager, Android

Starting today, you can download Android Studio 3.2 Beta. Previewed at Google I/O 2018, the latest release of the official Android IDE is focused on helping onboard you to all the new features launched around Google I/O -- Android JetPack, Android P Developer Preview, and the new Android App Bundle format. There are also several other exciting new features included in Android Studio 3.2 to accelerate your app development, such as Emulator Snapshots and the Energy Profiler.

As the usage of Android Studio has grown in the 3.5 years since version 1.0, we have also become increasingly obsessed with quality. We continue to invest in quality because we know that millions of app developers spend almost everyday in Android Studio and need a reliable set of tools. Stability, build times, and other quality work will be the primary focus for our next release once we finish Android Studio 3.2. We also did not want to wait, so we have made checkins to address memory leaks and performance issues as well as fixed more than 450 bugs. Thank you for the continued feedback and please keep it coming so we can focus on the areas you care about most in the next version of Android Studio. If want to try out the latest features, and assess the improvements in quality, you can download Android Studio on the beta release channel.

What is inside of Android Studio 3.2

Building on the canary release of Android Studio 3.2, the Beta release includes:

• Android App Bundle support - The Android App Bundle is a new publishing format that uses the Google Play's Dynamic Delivery, which delivers a smaller, optimized APK that only contains the resources needed for a specific device. Without any code changes, you can take advantage of the app size savings of an Android App Bundle by navigating to Build → Build Bundle / APK or Build → Generate Signed Bundle / APK.

• Emulator Snapshots - With Android Studio 3.2 you can create snapshots at any emulator state and then start a snapshot in under 2 seconds. You can pre-configure an Android Virtual Device (AVD) snapshot with the apps, data and settings that you want and then repeatedly go back to the same snapshot. Learn more.

• Energy Profiler - The new Energy Profiler in the performance profiler suite can help you understand the energy impact of your app on an Android device. You can now visualize the estimated energy usage of system components, plus inspect background events that may contribute to battery drain.
