Specifically, it includes a new set of templates in the New Project wizard and the New Module wizard to develop for the Android Things platform, but there’s a whole host of other features.
You’re looking at Kotlin and Java 8 language support, Layout Editor improvements, XML fonts, Instant App support, and build speed improvements.
Did I mention Oreo, too?
Google’s Product Manager for Android, Jamal Eason, introduces the new version of the IDE:
This release of Android Studio is packed with many new updates, but there are three major feature areas you do not want to miss, including: a new suite of app profiling tools to quickly diagnose performance issues, support for the Kotlin programming language, and a new set of tools and wizards to accelerate your development on the latest Android Oreo APIs.
As mentioned, there’s a lot of new features in the realm of application profiling, the area that sorts the professionals from the hobbyists!
Android Studio 3.0 includes a brand new suite of tools to help debug performance problems in your app. We completely rewrote the previous set of Android Monitor tools, and replaced them with the Android Profiler. Once you deploy your app to a running device or emulator, click on the Android Profiler tab and you will now have access to a real-time & unified view of the CPU, Memory, & Network activity for your app.
Each of the performance events are mapped to the UI event timeline which highlights touch events, key presses, and activity changes so that you have more context on when and why a certain event happened. Click on each timeline to dig into each performance aspect of your app.
For example, pictured above is the CPU profiler, to help optimise and debug your app’s code. You can inspect your app’s CPU usage and thread activity in real-time, and record method traces, so you can optimize and debug your app’s code
Pictured below is the Network profiler, to help examine how and when your app transfers data, and in theory optimise the underlying code. It displays realtime network activity on a timeline, showing data sent and received, and the current number of connections.
Google has provided these handy links to the main new features:
