Google announced a major Quick Share upgrade that will allow Android and iPhone users to share files directly from supported applications without opening a separate sharing menu. The company introduced a new Quick Share software development kit (SDK) at Android Dev Summit 2026, with plans to release it in the first half of 2027.
The SDK will allow developers to add Quick Share directly to Android and iOS apps, making it easier to transfer photos, videos, and other files between nearby devices.
How In-App Quick Share Changes the User Experience
Currently, users typically need to open their phone's sharing menu and select Quick Share to transfer files. With the upcoming SDK, apps will be able to offer this feature directly within their own interface. Instead of opening the full-screen Quick Share window, users will see a smaller panel at the bottom of the app. This panel will display previews of the selected files and allow users to start the transfer without leaving the application.
Google will also provide an iOS SDK, allowing developers to bring the same functionality to iPhone apps. However, the feature will only become available in applications whose developers choose to integrate it.
Technical Foundations: Offline Transfer and Encryption
Google says the new Quick Share SDK will transfer files directly between nearby devices using local connections. Transfers will use end-to-end encryption to protect information as it moves between devices. The SDK can automatically create a local hotspot when necessary and use Wi-Fi Direct on compatible devices.
Because files do not pass through cloud servers, users will be able to share them without an internet connection or mobile data. This means transfers could work in places without network coverage, including airplanes and subway tunnels. Photos and videos will also retain their original resolution because they do not need to be compressed before sharing.
Tap to Share Integration and Privacy Controls
The SDK will support Google's Tap to Share feature, which launched in August for supported Pixel and Samsung devices. With Tap to Share, users can initiate transfers by bringing compatible devices close together. Google says the receiving application will be able to launch automatically after the transfer finishes, even if it was not already open.
Developers will also have the option to mark files as sensitive. When enabled, the SDK will hide or mask their previews during the sharing process. According to Google, integrating Quick Share into an application requires approximately 20 lines of code. Developers will not need to maintain separate servers because transfers take place directly between devices.
Quick Share's Existing Reach and Future Expansion
Google has expanded Quick Share significantly over the past year. The company first introduced compatibility with Apple's AirDrop on supported Pixel phones before expanding that support to other Android manufacturers. In August, Google also introduced Tap to Share, allowing users of compatible Pixel and Samsung devices to transfer files more easily.
According to the company, Quick Share is now available on more than 3 billion devices across Android, ChromeOS, and Windows. The upcoming SDK will extend its capabilities by allowing third-party Android and iPhone applications to offer built-in file sharing. Google plans to release the SDK during the first half of 2027, although it has not announced an exact date. The availability of in-app sharing will depend on individual developers adding support to their applications.
Why the Upgrade Matters for Developers and Consumers
For developers, the SDK reduces the amount of code needed to add cross-platform sharing, lowering the barrier to entry for smaller teams. Because the SDK handles connection management, encryption, and hotspot creation, developers can focus on core app functionality. For consumers, the change promises a smoother workflow: sharing a photo from a messaging app or a document from a productivity suite will no longer require exiting the app to invoke the system share sheet.
Potential Impact on the Broader Mobile Ecosystem
By offering a unified sharing experience that works on both Android and iOS, Google aims to lessen the friction that has traditionally separated the two ecosystems. If major app publishers adopt the SDK, users could see a reduction in reliance on third-party cloud services for temporary file transfer. This could have implications for data usage, privacy compliance, and even competition among file-transfer solutions.
Next Steps and What to Watch For
Developers interested in the SDK should monitor Google's developer portal for documentation, sample code, and beta access details. Google has indicated a release window in the first half of 2027, but no exact launch date has been set. Early adopters are likely to be large app developers who can showcase the feature in upcoming updates.
Users should keep an eye on app update notes for mentions of Quick Share integration. As more apps embed the SDK, the in-app sharing panel will become a familiar element across a range of services, from social media to business productivity tools.
