Abstract:
Google recently announced at the Android Dev Summit developer summit that it will launch a new Quick Share SDK in the first half of 2027, and will also release the Quick Share iOS SDK for iPhone applications. This means that in the future, both Android and iOS applications can directly integrate the Quick Share function, allowing users to complete file sharing within the application without going through the system-level sharing menu or the full-screen Quick Share interface.
Quick Share's growth has accelerated significantly over the past year. This feature first realized interoperability with Apple AirDrop on Pixel devices, and then related support was gradually expanded to more Android devices. In August this year, Google launched the Tap to Share function to further enhance the cross-device transfer experience. Now, with the opening of the SDK, Quick Share will further extend from system functions to the third-party application ecosystem.
According to Google, after integrating the new SDK, when users share files within the application, they will directly see a sharing panel that pops up at the bottom instead of jumping to the system sharing interface. This panel can display preview information of the files to be sent, making the entire sharing process faster and smoother.
On a technical level, file transfers will be done over the local network, with end-to-end encryption implemented between the two devices. The SDK automatically creates hotspot connections as needed and enables Wi‑Fi Direct technology on supported devices. Because the data does not need to be compressed, photos and videos can be transmitted at their original resolution.
In addition, since the transfer process does not rely on cloud services at all, files can be shared normally even when offline. For example, on airplanes, deep in subway tunnels, or other environments without network connections, users can still complete data transfers between devices without consuming mobile data traffic.
For developers, Google said the access cost is relatively low, requiring only about 20 lines of code to complete the integration, and there is no need to build and maintain additional server infrastructure. Apps can also mark certain content as sensitive information so that it is automatically hidden in the preview interface.
When used with Tap to Share, the app on the receiving device doesn't even need to be opened in advance. When the file transfer is completed, the target application will automatically launch, further reducing user steps.
Google revealed that Quick Share currently covers more than 3 billion devices on Android, ChromeOS and Windows platforms. However, whether the new features will eventually appear in commonly used applications depends on whether developers are willing to adopt the soon-to-be-released Quick Share SDK.
