Form Factors at Android Developer Summit ‘22

Posted by Alex Vanyo, Developer Relations Engineer

The Android Developer Summit is live with the second stop on our world tour - and we are thrilled to give you the latest updates on Android form factors! Discover the latest tools, APIs and guidance that make it easier to build apps that look great on large screens, wearables, and TVs.

Here are the three things you need to know about form factors at ADS, and check out the full YouTube playlist here:

#1: Android developers are finding BIG success when optimizing their apps for large screens

The large screen category is growing, with over 270 million active large screen Android devices and an expanding portfolio of tablets, desktops, and foldables to choose from. That’s why there has never been a better time to be sure your app looks great across all screen sizes and postures. To learn practical tips for optimizing your app for large screens, check out the Do’s and Don’ts: Mindset for optimizing apps for larger screens session. Throughout the session, the Android team highlights design guidance, app quality, and additional tips for large screens on everything from reachability to canonical layouts. New Android Studio tools like emulators and reference devices make it easier to build and test.In-depth guides help you improve your app by optimizing layouts, avoiding camera issues, and enhancing support for peripherals like mouse, keyboard and stylus.

Large screens enable users to see more, do more, and experience more. With large screen sizes, there are ever-expanding opportunities to excite and delight your users with differentiated app experiences. That’s why we launched our new large screens gallery page during the Android Dev Summit kickoff, with general design tips and verticalized use cases, and implementation ideas.

#2: It’s easier than ever to develop for Wear OS

Compose for Wear OS is stable, bringing the modern UI toolkit to the wrist and making it simpler than ever to build exceptional Wear OS apps. This toolkit is designed to help you get your app up and running faster than before; Outdooractive adopted Compose for Wear OS and enhanced their wearable experience with 30% fewer development hours. Equally important as development time is the user experience you are able to provide. Todoist rebuilt their app using Compose for Wear OS, saw their growth rate on Google Play increase by 50%, and heard positive feedback internally and on their social media channels. To begin developing with Compose for Wear OS, get started on our curated learning pathway for a step-by-step learning journey. Where you can find documentation including a quick start guide and get hands on experience with the Compose for Wear OS codelab!

The Android Developer Summit technical sessions dive deep into the content you need to build Wear OS apps, with guidance on app architecture, testing, handling rotary input and verticalized sessions for media and fitness. We have seen the impact that Health Services has had on developing health and fitness apps for the wrist, and how powerful this can be when extended with Health Connect on mobile. Using Google APIs and tools, Strava improved their user engagement and retention - with 30% more active days from Wear OS users on Strava than users without a wearable device.
