Android Dev Summit: Google Details Kotlin, Jetpack, and Instant App Improvements



Google launched its Android Developer Summit in Mountain View this week with a blow, and support for collapsible devices only scratches the surface. The company announced that many of the new features in Kotlin 1.3 now supported nationally, and it provided updates on Jetpack, Android Studio, Instant Apps, and more.

Kotlin 1.3

First up was Kotlin, a static written programming language from JetBrains running on Java virtual machine. The latest version – 1.3 – was released last week, bringing a host of features:

  • Inline classes allow you to create a type that does not allocate with less box.
  • Unsigned numbers are now part of the Kotlin standard library, including UInt, UByte and ULong.

    Multiplatform code previously written for Android, or JVM can now also be directed to Javascript or native.

  • The support for Coroutines is now stable.

All these

Jetpack and Android X

Google revealed Jetpack, a suite of tools and APIs that developed "accelerate" Android app development, on Google I / O 201

8 in May, and it's taken off as a missile (no pun intended) in the months ago. Today, 80 percent of the top 1000 apps and games have passed it, according to Google. And this week, the company describes two new Architecture Component Libraries that promise to make it even more attractive: Navigation, Work Processing and Slice.

Navigation and Work Administrator – both launchers in beta this month – offer a simplified way to implement Android's navigation principle with animated transitions, create and edit navigation flow, and perform background tasks in "the most effective way" based on application status, device API- level and other factors.

Android pieces, on the other hand – unveiled on Google I / O, and this week go to public search experiments – show mini applets containing content and actions for example to play a video or book a flight. The list of introductory partners includes Doist and Kayak.

Android Studio 3.3 beta 3

Android Studio, Google's official IDE for Android development, got some love during the dev conference its first keynote. Android Studio 3.3 beta 3 launches today and focuses on stability – especially "user-impact" bugs. The frequency of crashes, hangers, and memory usage is reduced, and Google said there is building tools that will "help [developers] easily understand" what lowers an app downlay.

 Android Instant Apps

Last but not least, Google revealed improvements to the instant apps. In Android Studio 3.3, developers can deploy and build instant apps and installed apps from a single Android Studio project and include them in a single Android App suite.
