(Or do all three to help you remember! There won't be a quiz.) Evolving Android's early-access programs: Introducing the Canary channel 🐦 Android has introduced a new Canary release channel for its early-access programs, replacing the previous developer preview model. This channel provides earlier and more consistent access to in-development platform features throughout the year. The new Canary channel offers continuous, rolling over-the-air (OTA) updates for supported Pixel devices, addressing previous limitations where previews required manual flashing and the preview program ended once a platform version reached Beta, requiring manual flashing to enter it again for the next cycle. You can use the Canary channel to: Access new features and potential behavior changes in their earliest stages. Integrate builds into your Continuous Integration (CI) systems to identify app compatibility issues early. Download Canary SDKs through the SDK Manager and access builds via the Android Studio Canary channel for development and testing. The Canary channel operates in parallel with the existing Beta program. Canary builds are bleedin ## A product manager's guide to adapting Android apps across devices DevFeed: [A product manager's guide to adapting Android apps across devices]() Original publisher: [Read original article]() Author: Android Developers Published: 2025-06-10T18:06:14Z Content type: article Language: en Sources: [Android Developers - Medium]() Topics: [Android](), [Large Screen](), [Mobile](), [Development](), [App](), [API](), [Google](), [SDKs]() Tags: [adaptive](), [android](), [android-16](), [android-apps](), [api](), [developer](), [developer-preview](), [featured](), [google-io-2025](), [large-screen](), [large-screen-display](), [layout](), [mobile](), [mobile-apps](), [platform](), [sdk](), [ui]() ### AI overview This guide explains why Android developers should adapt apps for phones, foldables, tablets, Chromebooks, cars, Wear, and XR. It discusses Android 16 changes for apps targeting SDK 36, including changes to orientation and resizability restrictions on large-screen devices, and describes the user-experience, development-efficiency, and market-reach benefits of adaptive apps. ### Source excerpt Posted by Fahd Imtiaz, Product Manager, Android Developer Experience This article is also shared on the Android Developers Blog Today, Android is launching a few updates across the platform! This includes the start of Android 16's rollout, with details for both developers and users, a Developer Preview for enhanced Android desktop experiences with connected displays, and updates for Android users across Google apps and more, plus the June Pixel Drop. We're also recapping all the Google I/O updates for Android developers focused on building excellent, adaptive Android apps. With new form factors emerging continually, the Android ecosystem is more dynamic than ever. From phones and foldables to tablets, Chromebooks, TVs, cars, Wear and XR, Android users expect their apps to run seamlessly across an increasingly diverse range of form factors. Yet, many Android apps fall short of these expectations as they are built with UI constraints such as being locked to a single orientation or restricted in resizability. With this in mind, Android 16 introduced API changes for apps targeting SDK level 36 to ignore orientation and resizability restrictions starting with large screen devices, shifting toward a unified model where adaptive apps are the norm. This is the moment to move ahead. Adaptive apps aren't just the future of Android, they're the expectation for your app to stand out across Android form factors. Why you should prioritize adaptive nowSource: internal Google data Prioritizing optimizations to make your app adaptive isn't just about keeping up with the orientation and resizability API changes in Android 16 for apps targeting SDK 36. Adaptive apps unlock tangible benefits across user experience, development efficiency, and market reach. Mobile apps can now reach users on over 500 million active large screen devices: Mobile apps run on foldables, tablets, Chromebooks, and even compatible cars, with minimal changes. Android 16 will introduce significant advancements i ## Material Design for XR (Developer Preview) DevFeed: [Material Design for XR (Developer Preview)]() Original publisher: [Read original article]() Published: 2024-12-12T13:00:00Z Content type: release Language: en Sources: [Material.io - Material Design]() Topics: [Material Design](), [ui](), [Framework]() Tags: [building](), [design](), [developer](), [developer-preview](), [preview](), [tools](), [ui]() ### AI overview Material Design for XR is presented as a developer preview focused on building user interfaces that adapt to extended reality using familiar frameworks and tools. ### Source excerpt Building UI that adapts for XR with familiar frameworks and tools ## Temporal Cloud is now in Expanded Access DevFeed: [Temporal Cloud is now in Expanded Access]() Original publisher: [Read original article]() Author: Charles Zedlewski Published: 2022-11-02T04:00:00Z Content type: release Language: en Sources: [Temporal Blog]() Topics: [Cloud](), [Software](), [Development]() Tags: [announce](), [automation](), [cloud](), [developer-preview](), [enterprise](), [latency](), [preview](), [product-news](), [production](), [scaling](), [security](), [self-service](), [updates](), [uptime]() ### AI overview Temporal Cloud has moved from developer preview to expanded access, removing the waitlist and replacing it with a signup form.

It means that all icons starting from Android 12 will be the same color and change dynamically based on wallpapers. Android 12 introduced a beta option for enabling Themed Icons, but icons looked inconsistently across the system. Only Google apps had themed icons, other looks the same as previous. Android 12 So far not available no API for developers. I found only a few materials on how to implement themed icons on Android 12. For example: Material You App Icons: Part Way There Briefly, we need to override icon colors in the values-v31 folder to use new Material You colors. It will work, but with several limitations: Changing color in the system doesn't apply to the launch icon. Only after reinstall. Disabling the Themed icons feature doesn't affect the launch icon. Simply, the icon has dynamic color permanently. It's logical, the application can't have two launch icons simultaneously. The Pixel Launcher does the whole magic under the hood and stores an additional set of icons with monochrome icons for all Google apps. Pixel Launcher APK resourcesAndroid 13 way Google recently announced the first Developer Preview of Android 13, while there are a lot of new APIs. One of them is that developers got access to API for Themed app icons. To implement the new approach, we need to take several steps: Clear icon from shadows, unnecessary details and etc. Otherwise, the icon will differ from the uniform style. Icon with shadow 2. Add attribute to the element. monochrome tag in icon resourceNote: If android:roundIcon and android:icon are both in your manifest, you must either remove the reference to android:roundIcon or supply the monochrome icon in the drawable defined by the android:roundIcon attribute. That's all, the system automatically applies tint color for the monochrome icon.
