Quick Share SDK to Arrive in 2027: File Sharing Right Inside Apps

⚡ The gist in 5 seconds

• Google announced the Quick Share SDK at Android Dev Summit 2026 — file sharing gets embedded directly into third-party apps.
• Works on Android and iOS, with the release scheduled for the first half of 2027.
• Files travel over the local network via Wi-Fi Direct with end-to-end encryption: no internet, and no compression of photos and videos.

🔍 What happened

Google took the stage at Android Dev Summit 2026 with the Quick Share SDK. It's a toolkit that gives third-party apps direct peer-to-peer file sharing between devices. Both platforms are promised — Android and iOS. The timeline is stated without any wiggle room: the first half of 2027. The announcement was covered by Habr.

Here's how it works. The SDK spins up a hotspot on its own, and on supported devices it connects via Wi-Fi Direct — traffic never goes to the internet, transfer happens within the local network. Encryption is end-to-end, between the two devices. Photos and videos aren't recompressed. The system "Share" menu and the full-screen Quick Share interface are no longer required: sharing is embedded into the app, and when launched, a bottom panel slides up with a preview of what you're sending.

🧠 Our take

Why now. Quick Share has long existed as a system feature, but the moment you step outside it, the user drops into a separate full-screen interface and loses the app context. The SDK eliminates exactly this gap. Our assessment: Google isn't so much adding a new feature here as expanding the territory where Quick Share exists at all.

What it changes for us. Sending a file between two phones in the same room usually means opening a messenger that will compress the video and push it through someone else's server. Here, original quality, low latency, and offline operation are promised — on a trip, in roaming, anywhere traffic is expensive or unavailable. For the market, it's one more argument in favor of the Google ecosystem against AirDrop, which remains closed at Apple.

Who wins. Developers: no need to build their own transfer infrastructure — Google explicitly states there are no maintenance costs. Users: fewer jumps between screens. Who loses — in our view, messengers and cloud file storage: some of the scenarios for which people used to pay with data plans and subscriptions are moving to the local network. And there's a separate question — iOS. There, Google becomes a supplicant on someone else's platform, where Apple sets the rules. It looks like a long negotiation path, not a release "tomorrow."

⚠️ What we don't know

The weakest point of the announcement is the numbers. There's no transfer speed, no file size limit, and no list of devices with Wi-Fi Direct. It's unclear how the SDK will behave on the iPhone: Apple doesn't open access to the necessary system APIs as generously. The source is also silent about the SDK's pricing and about backward compatibility with older versions of Android. This should be verified via the developer documentation once it appears, not via conference slides.

Prediction: by the end of the first half of 2027, the SDK will launch for Android, while the iOS version will lag by at least six months — that's our bet.
