Safer and more secure devices with Project Mainline

Project Mainline builds on our investment in Treble to simplify and expedite how we deliver updates to the Android ecosystem. Project Mainline enables us to update core OS components in a way that's similar to the way we update apps: through Google Play. With this approach we can deliver selected AOSP components faster, and for a longer period of time – without needing a full OTA update from your phone manufacturer. Mainline components are still open sourced. We are closely collaborating with our partners for code contribution and for testing, e.g., for the initial set of Mainline components our partners contributed many changes and collaborated with us to ensure they ran well on their devices.

Project Mainline updates via Google Play infrastructure components in the Android OS Framework. The Framework components updated are located above the Treble Interface and Hardware-specific implementation, and below the Apps layer.

As a result, we can accelerate the delivery of security fixes, privacy enhancements, and consistency improvements across the ecosystem.

Project Mainline has security, privacy and consistency benefits. Security: Accelerate pushes and remove OEM dependency for critical security bugs. Privacy: Better protection for user’s data; increased privacy standards. Consistency: Device stability and compatibility; developer consistency.

‣ Security: With Project Mainline, we can deliver faster security fixes for critical security bugs. For example, by modularizing media components, which accounted for nearly 40% of recently patched vulnerabilities, and by allowing us to update Conscrypt, the Java Security Provider, Project Mainline will make your device safer.

‣ Privacy: Privacy has been a major focus for us, and we are putting a lot of effort into better protecting users’ data and increasing privacy standards. With Project Mainline, we have the ability to make improvements to our permissions systems to safeguard user data.

‣ Consistency: Project Mainline helps us quickly address issues affecting device stability, compatibility, and developer consistency. We are standardizing time-zone data across devices. Also, we are delivering a new OpenGL driver implementation, ANGLE, designed to help decrease device-specific issues encountered by game developers.

Our initial set of components supported on devices launching on Android Q:

Security: Media Codecs, Media Framework Components, DNS Resolver, Conscrypt
Privacy: Documents UI, Permission Controller, ExtServices
Consistency: Timezone data, ANGLE (developers opt-in), Module Metadata, Networking components, Captive Portal Login, Network Permission Configuration

Project Mainline enables us to keep the OS on devices fresher, improve consistency, and bring the latest AOSP code to users faster. Users will get these critical fixes and enhancements without having to take a full operating system update. We look forward to extending the program with our OEM partners through our joint work on mainline AOSP.
