In developing countries, the number of developers using Android IDE has almost tripled in just two years. With growth like this, Google has made it a antecedence to better serve its association by acceleration down on its effort to serve developers. And it’s doing just that.

Here are a scattering of our admired new or adapted Android dev tools from day one of Google I/O.

Today Google appear Android Jetpack, a way to advance app development by bringing calm the allowances of Abutment Library with a larger set of apparatus that allow developers to ditch boilerplate code. It manages accomplishments tasks, navigation, and lifecycle administration to give devs what they need to differentiate their app from competitors.

If that weren’t enough, Google also appear Android KTX, part of Jetpack that added optimizes the Kotlin developer acquaintance “across libraries, tooling, runtime, affidavit and training.” According to Google:

Tooling continues to advance with Android Studio, Lint support, and R8 optimizations. We have even tuned the Android Runtime (ART) in Android P, so that apps built with Kotlin can run faster

Not one to shy away from a well-deserved pat on the back, Google appear today that over a third of all “pro” developers are using Kotlin, and that 95 percent of them have appear being happy with it.

And it shows. The number of Play Store apps using Kotlin grew sixfold in the past year.

You can find Kotlin code snippets in the official documentation, and Google promises even more in the API advertence affidavit it plans to absolution later today. If you’re in need of a Kotlin kickstart, there’s a bootcamp on Udacity, and a specialization in the Google Developers Experts Program.

Or, you can just try it yourself.

It’s also worth advertence the suite of tools accessible in Android Studio 3.2. Inside you’ll find a number of appearance for Jetpack, including a visual Aeronautics Editor and new code refactoring tools. The newest absolution has tools for the new Android App Bundle format, Snapshots in the Android emulator, and a new R8 optimizer for a abate download and install. Then there’s the new Energy Profiler, an Android Studio affection that helps to adviser an app’s impact on array life.

You can download the latest adaptation of Android Studio 3.2 Canary here.

My admired new dev affection for Android was after a doubt the new Android App Bundle, a publishing format that promises to acutely reduce app size.

It works by bundling your app with aggregate needed for any device, including: all accurate languages, every device screen size, and every accouterments architecture. Developers can also modularize the install by carrying appearance on-demand, instead of just during install. Put simply, users get the pieces they need, and can download more over time, as needed, using Google Play Dynamic Delivery.
