Google is showing some love for Wear OS at #GoogleIO 2023. Here’s a summary of what they announced, including the new Wear OS 4 Developer Preview based on Android 13 👀!
Do you like watch faces? It’s the thing you stare at/interact with the most, so it’s no surprise they get a lot of attention. Samsung and Google have teamed up to announce the Watch Face Format: a new way to build watch faces for Wear OS.
According to Google, the Watch Face Format is a declarative XML format to design the appearance and behavior of watch faces. There won’t be any executable code involved in making a watch face, and no code will be embedded in the watch face APK.
Wear OS takes care of rendering the watch face so you don’t have to worry about optimizing your code for battery performance. Watch faces built with Watch Face Format are easier to maintain than ones built with the Jetpack Watch Face library.
The reason is that you won’t need to update your watch face to take advantage of future platform optimizations or bug fixes. Also, you don’t need to build your own watch face editor — it’s included as part of Wear OS 4 itself.
You can build and publish watch faces in the Watch Face Format starting today in preparation for upcoming Wear OS 4 watches. You can create analog and digital watch faces, watch faces with complications, customizable watch faces, and more.
You can build watch faces directly in the new Watch Face Format or you can integrate it into your creation tools. Samsung, for example, released a new version of Watch Face Studio that lets you build watch faces in Watch Face Format without writing XML directly.
If you use Samsung’s Watch Face Studio to build a watch face, they’ll use the Watch Face Format by default when they’re run on a Wear OS 4 watch. Otherwise, they’ll run as a traditional watch face when run on a Wear OS 3 watch.
Wear OS 4 based on Android 13 will launch in the fall but can be tested out right now through the Wear OS 4 emulator, available through Android Studio.
Wear OS 4 based on Android 13 will bring backup and restore support (finally!), general performance and battery improvements, and permissions transfer for apps on your phone.
Google has announced that in Android 14, Health Connect "will be a core part of Android and available on all Android mobile devices." As I previously reported, this is because Health Connect is being shipped as part of a new, mandatory Project Mainline module.
Health Connect in Android 14 will introduce a new exercise routes feature to let users share maps of their workouts and improvements to menstrual cycle logging. And because it's a new Mainline module, it can be updated through Google Play System Updates.
Here's a screenshot of Health Connect integrated into Privacy settings.
Google highlighted some major improvements to Jetpack Compose at #GoogleIO 2023. Here’s a summary of some of the highlights:
In the latest alpha release, Google says they’re seeing an average 22% performance gain for Text and TextField after migrating modifiers to a new and more efficient system. To take advantage of this, update your Compose version.
Compose now also supports the latest emoji version and new text features like outlining text, hyphenation, and line breaking behavior configuration.
What’s new in Android Studio? A lot of things, some of which make use of generative AI to improve your workflow. Here’s what got announced at #GoogleIO 🧵
Android Studio Hedgehog (the latest Canary version, and no, its logo isn’t Sonic) adds a new AI-powered conversational feature called Studio Bot, better tools to develop for multiple form factors, and new insights, debugging, and testing solutions.
Studio Bot is an AI-powered conversational experience that leverages Codey, Google’s foundation model for coding, to help you generate code for your app. You can also ask it questions about Android development or to help you fix errors in your code.
At this year’s #GoogleIO, Google is announcing a bevy of new features for Google Play, including many that leverage generative AI to make it easier to market your app. Here’s a summary of what they announced 🧵:
A new AI tool will help you get started with making a store listing for your app. Just enter a few prompts like audience and key theme, and Google Play’s AI helper will generate a draft you can edit, discard, or use. This is currently only available in English.
Google Play will show review summaries created by Google’s generative AI technology. These summaries — starting with English but expanding later this year — will help users quickly learn about your app from what other users have been saying about it.
Here’s what’s new with Android for Cars (Android Auto and Android Automotive OS), as announced at #GoogleIO 2023. The biggest announcement IMO is Android Automotive OS 14 based on Android 14 and the new multi-screen feature it’ll bring 👀
Before I get ahead of myself, though, let’s recap Google’s announcements, starting with why you should care. Google expects the # of cars running Android Automotive OS with Google built-in to nearly double by the end of 2023.
Google’s only counting cars whose makers have licensed Google apps (hence “Google built-in”), so there’ll be even more cars running Android Automotive on the streets as some makers opt not to license Google Automotive Services (GAS).
The #GoogleIO keynote has kicked off with an appearance from Sundar! In this thread I'll talk about anything new Google announces that's directly related to Android. 👇
Immersive View in Google Maps for Android is getting a major revamp! You'll be able to see an immersive view of your routes and any relevant weather info.
Coming to 15 cities by the end of the year.
Google Photos is getting a new AI-powered Magic Editor feature! This is rolling out later this year.
