Microsoft is using Windows 11 taskbar to resume your Android activities

1 Share

Microsoft’s latest Windows 11 Insider Preview Build 26220.7271 brings a new cross-device feature that lets you resume what you were doing on your Android phone directly on your Windows PC. The M365 Copilot app on your phone from some brands can now hand off your browsing activity or cloud documents to the PC with a single click.

This update builds on Microsoft’s earlier rollout in August, where only Spotify supported cross-device resume. The system works through the Link to Windows app and Microsoft’s Continuity SDK, which quietly sends “app context” from your phone to the PC so Windows can reopen the same activity.

Your PC can now resume online files from the M365 Copilot Android app

The new Insider Preview update for Dev and Beta channels brings support for continuing online Word, Excel, and PowerPoint files opened inside the M365 Copilot app on your Android phone.

Microsoft says that if these Office apps are installed on your PC, the files open there. If not, Windows opens the online version in your browser. Note that it only works for online documents, since local files still stay locked to your phone.

M365 Copilot app and OneDrive in a Samsung phone

Currently, only phones from Samsung, Honor, Huawei, Oppo, and Vivo have this feature. The absence of Xiaomi and Motorola looks strange for now, because both brands have a good presence in several markets. As expected, Google’s Pixel lineup are also absent from the list.

If you use a Vivo phone, you can now pick up your Vivo Browser session on your Windows 11 PC’s default browser without having to do anything extra. The phone sends the active tab to your PC, and Windows shows a small alert on the taskbar that opens the same page in your PC browser.

How the cross-device resume actually works

Windows Latest understands that, at the technical level, all of this works through the Link to Windows app and a background layer that Microsoft calls the Continuity SDK.

Your phone creates a small “context packet” that contains the app, the content you are using, and instructions on how your PC should continue it. Windows receives that packet through the Cross Device Experience Host and launches the correct app or browser tab.

General illustration of the working of cross device file handoff with M365 Copilot

Cross-device resume runs on top of Microsoft’s Continuity SDK, which gives Android apps a way to describe what the user is doing and hand that context over to Windows. The core piece here is what Microsoft calls AppContext.

It is a small packet of metadata that tells Windows what activity the user wants to resume, which app it came from, when it was created, and where it should resume on the PC. Every AppContext needs a unique ID, a creation time, an app ID, and a type (in this case, resume activity).

If they choose to, developers can attach a preview image, a title, an intent URI, or a weblink.

Info Notice

An intent URI is a special Android-style deep link that tells Windows which app should open the resumed activity. Basically, it’s a URI (Uniform Resource Identifier) that encodes the target app and the action it should perform. Deep links (whether intent URIs on Android or protocol URIs on Windows) are links that open a specific location inside an app instead of just launching it, like opening a specific document, web page, or view directly.

Windows uses this metadata to figure out whether it should launch a desktop app through a registered URI protocol or fall back to opening a link in the browser.

However, the handoff only works if the partner app has integrated the Continuity SDK correctly. The app must initialize the SDK, wait for a onContextRequestReceived callback from Link to Windows, and then send its AppContext using AppContextManager.sendAppContext. If the system disconnects, the app must stop sending context.

Link to Windows is the background process that keeps everything connected. So, if your phone suspends it from running in the background, maybe to save battery, this feature may not work as intended.

Link to Windows runs on your phone, maintains the link to the PC, and receives each AppContext the moment the app pushes it. If the SDK sees that the phone and PC are linked and the context is valid, Windows generates a resume alert on the taskbar.

Resume alerts won’t appear unless a few conditions are met.

The phone must have Link to Windows running in the background, the user must have paired the phone with the PC, and the partner app must be approved by Microsoft because resume is a limited-access API. Apps also need explicit approval to interact with Link to Windows.

On the Windows side, as of now, the device must be running Insider Build 26220.7271 with CDEH (Cross Device Experience Host) provisioning so the system can understand the AppContext schema and activate the right desktop app through URI or weblink.

Microsoft’s documentation also explains why offline files on phones are not supported yet. A resume handoff only works when the file or activity can be referenced through a URI or a weblink. Offline files stored locally on the phone do not have a sharable endpoint that Windows can open, so the resume pipeline cannot hand them over. That is why only online Word, Excel, and PowerPoint files opened in the M365 Copilot app qualify for this experience right now.

However, the documentation doesn’t explain why only Samsung, Honor, Huawei, Oppo, and vivo support cross-device resume. But the Resume API is a Limited Access Feature that requires OEM apps to integrate the Continuity SDK, add specific metadata, and work closely with the Link to Windows service. Only manufacturers that have completed this integration are currently supported.

Cross Device Resume sounds good on paper, but getting it to work is hard

I use a Motorola phone, so the feature isn’t available for my device, despite Motorola’s growing popularity in the US.

Undeterred, I got to work with my mom’s Samsung phone to test the feature. I am on the Dev channel with the latest Insider Build. All permissions in Link to Windows are enabled. The same Microsoft account is up and running on the M365 app as well. I have also manually enabled the feature. However, after multiple tries, the feature didn’t work.

But you can try your luck with the steps below:

How to enable the new Resume-from-Phone feature in Windows 11

  • Install the latest Windows 11 Insider Preview Build 26220.7271 (KB5070307) in the Dev or Beta Channel.
  • Go to Settings > Bluetooth & devices > Mobile devices.
  • Turn on “Allow this PC to access your mobile devices.”
  • Click Manage devices, and pair your Android phone (Samsung, Honor, Huawei, Oppo, or vivo) via Bluetooth.
  • Open the Link to Windows app on your phone, follow the setup prompts, and make sure the app is allowed to run in the background.
  • In the Manage Devices setting on your PC, make sure that “Resume” feature is turned on. Turn on Resume feature in Windows 11 Settings
  • Now, trigger a resume event and if everything works well, you’ll see the resume car appear on your PC taskbar. Click it to continue the activity on your PC.

These are the three cross-device resume features available now:

  1. Vivo Browser for browser-session resume
  2. M365 Copilot app for online Word, Excel, and PowerPoint files
  3. Spotify (earlier rollout) for audio resume

Microsoft is trying to make up for the lack of an ecosystem

Microsoft clearly wants Windows to have its own version of Apple’s Handoff, where you can start something on one device and pick it up on another. The intention is good, and the tech behind it is exceptional.

But the execution is far from the perfect experience that Apple users are so used to by now, that once they buy one Apple product, the chances of them completing the “ecosystem” are pretty high.

Of course, the biggest issue here is Android’s fragmentation. Unlike Apple’s walled garden, Android is a collection of different manufacturers. Without OEM-level integration of the Continuity SDK and the required metadata, Windows doesn’t hold a candle against Apple’s Handoff.

Speaking of Apple, iPhones are out of this conversation entirely as Microsoft notes “iOS applications are not supported for integration with the Continuity SDK at this time.”

Getting the Phone Link iOS app to run in the background alone would be a gargantuan task for Microsoft. As for iPhone users who have a Windows PC, we believe that cross device resume feature would take a fairly long time to arrive, unless Microsoft works out any miracles, which we are wishing they would, considering that Apple is planning to launch a budget MacBook soon.

And the iPhone users who didn’t let go of their Windows PC till now, just because they don’t want to spend a fortune on Apple hardware, may finally switch to macOS, and never look back. The implications of a budget MacBook entering the $800 Windows PC monopoly are staggering.

All hope is not lost as Microsoft still can woo Android OEMs to get their devices to talk better with Windows. These manufacturers want it as much as Microsoft because it’s the only way for them to grow their market share.

Before that happens, Microsoft has a few things to fix. The resume pipeline needs to get more reliable, the device list should expand beyond a handful of OEMs, and the onboarding process for developers needs to be much simpler than the current Limited Access Feature request system.

That being said, if you’re a developer and you want to add cross device resume in your app, well, Microsoft is actually inviting people like you to do so. Check out the Microsoft support document for Cross Device Resume (XDR) using Continuity SDK (Android and Windows Applications).

The feature is currently rolling out to Insiders in the Dev and Beta channels only, and there is no word on when it will come to regular PCs.

Pebble Goes Fully Open Source

1 Share
Core Devices has fully open-sourced the entire Pebble software stack and confirmed the first Pebble Time 2 shipments will start in January. "This is the clearest sign yet that the platform is shifting from a company-led product to a community-backed project that can survive independently," reports Gadgets & Wearables. From the report: The announcement follows weeks of tension between Core Devices and parts of the Pebble community. By moving from 95 to 100 percent open source, the company has essentially removed itself as a bottleneck. Users can now build, run, and maintain every piece of software needed to operate a Pebble watch. That includes firmware for the watch and mobile apps for Android and iOS. This puts the entire software stack into public hands. According to the announcement, Core Devices has released the mobile app source code, enabled decentralized app distribution, and made hardware more repairable with replaceable batteries and published design files.

Xbox Crocs are real

1 Share

Microsoft is loving Crocs at the moment. After releasing Windows XP-themed Crocs earlier this year, the software maker is now putting an Xbox controller on your feet with a new limited edition pair of Crocs.

Available on November 25th for $80, the Xbox Crocs mimic the Xbox One X’s controller with fixed buttons and joysticks. Both Crocs feature the classic X, Y, B, A buttons, D-pad, left and right analog sticks, and even a white Xbox button and bumpers on the sides. The Xbox logo also appears on the ankle strap’s hinges.

Microsoft and Crocs are also releasing a five-pack of shoe charms for $20, with characters and icons from Halo, Fallout, Doom, World of Warcraft, and Sea of Thieves.

It’s all part of a collaboration between Crocs and Microsoft that marks 20 years since the Xbox 360 was first released. The company’s Windows XP-themed Crocs were also part of Microsoft’s 50th anniversary celebrations.

Why the AI Bubble Conversation is Useless

1 Share
From: AIDailyBrief
Duration: 14:02
Views: 93

The AI bubble debate is mainly a market discussion with limited relevance for operators and end-users. Sentiment is concentrated in a few big companies, macroeconomic pressures stem from weak consumer finances and tight Fed policies, and unprecedented multi-year capital expenditure commitments make the profit outlook largely unpredictable. Important signals to monitor include datacenter financing arrangements, increasing corporate debt and credit-default-swap prices, and the spread of media-driven fad reports, even as focus stays on practical AI adoption and workflow transformation.
