3 things to know about Jetpack from Android Dev Summit 2019

Posted by Jisha Abubaker, Product Manager

Last month’s #AndroidDevSummit was jam-packed with announcements and technical news…so much that we wouldn’t be surprised if you missed something. So all this month, we’ll be diving into key areas from throughout the summit so you don’t miss anything. We previously spotlighted Jetpack Compose, Kotlin and Android Studio, and today, we’re highlighting the rest of Android Jetpack, with the top three things you should know:

#1: A number of new & updated Jetpack libraries ready to use:

WorkManager 2.2 (Stable) has landed significant updates in the last releases with features like on-demand initialization improving app startup time when using WorkManager and improved testing support. Hear more of the new features and best practices.

Room 2.2 (Stable) is packed with features you asked for too : pre-packaged databases, improved relationship support and now better support for Kotlin Flow as well. Check out the What’s new in Room session to catch up.

Benchmarking (Stable) helps you measure the performance of tasks in your app with confidence. Here’s a deep dive on how you can exercise the library in fighting performance regressions in CI, like we do ourselves for Jetpack libraries and Compose.

LiveData w/ support for Kotlin coroutines & Flow (RC) : Kotlin coroutines and Flows has been the Android developer community’s interest in simplify async patterns in your apps. Learn how best to take advantage of the liveData builder in your app:

View binding (Beta) is type-safe solution bundled with Android Studio 3.6 Beta with minimal build-time impact, no more findViewById(), no more annotation processors. Check out What’s new in Studio for a demo !

#2: We’re busy baking more libraries

CameraX (Alpha) simplifies the development experience and lets you focus on your app instead by addressing the differences between the many devices in the Android ecosystem, like Samsung, Xiaomi, Oppo, Motorola, LG who are already unifying behind CameraX. Expected in Beta soon, learn what the Camera team has been up to since I/O 2019.

Security (Alpha) helps you simplify data at rest encryption for your app needs. Hear of best practices with encryption on Android from the Security library team.

#3:It’s time to migrate to androidx!

With all the new and updated Jetpack libraries and upcoming release of Jetpack Compose, it is time to get your app updated and ready. Nick and Tiem share a great step by step plan and best practices from the community in migrating to androidx namespace.

…and we also heard from you!

But Android Dev Summit isn’t just about what we’ve got to say; it’s also about you telling us what you’d like to see worked on to make your life easier. And this year, one thing that we heard strongly from our community was the need to provide a simplified Dependency injection developer experience for Jetpack libraries and expand improved Kotlin support to other Jetpack libraries! We’re on it!

You can find the entire playlist of Jetpack sessions at the Android Dev Summit sessions and videos here. We’ll continue to spotlight other areas later this month, so keep an eye out and follow AndroidDevelopers on Twitter. Thanks so much for letting us be a part of this experience with you!
