Google Announces Quick Share SDK for Third-Party Apps

At the Android Dev Summit 2026 conference, Google officially announced the Quick Share software development kit (SDK). This toolkit will allow third-party Android and iOS apps to directly integrate peer-to-peer file transfer capabilities.

The release of the Quick Share SDK is scheduled for the first half of 2027. Developers will be able to build file sharing directly into their applications, sparing users from opening system share sheets.

• Direct file transfer SDK integration for Android and iOS apps
• End-to-end encryption (E2E) ensuring high data privacy and security
• Wi-Fi Direct support and offline mode for internet-free transfers
• Convenient bottom sheet interface with file previews

Technical Capabilities and Security The new SDK focuses on delivering maximum transfer speed and robust security. Data transmission is protected via end-to-end encryption directly between two devices operating within a local network environment.

The SDK automatically manages hotspot creation and utilizes Wi-Fi Direct technology on compatible hardware. This mechanism ensures minimal latency and the highest possible file transfer speeds.

Offline Support and Cross-Platform Reach A key highlight of the Quick Share SDK is its fully functional offline mode. This proves exceptionally useful in scenarios where users lack internet access or face strict data traffic limitations.

Google will also provide an iOS version of the Quick Share SDK, allowing iPhone users to benefit from this seamless file-sharing functionality inside compatible third-party applications.

User Interface and Ecosystem Impact Regarding the user interface, triggering Quick Share within a third-party app will prompt a bottom sheet to appear on the screen, letting users preview the files they intend to send.

This launch empowers developers to enhance user workflows natively. Additionally, Google highlighted its Registered App Stores initiative, allowing alternative app marketplaces to apply for participation.
