Google has introduced Android Halo, an interface layer for Android 17 that keeps an AI agent visible in the status bar while it operates in the background. This feature was first mentioned at Google I/O in May 2026 and detailed by Android president Sameer Samat in a July YouTube video. Android Halo allows users to monitor the AI agent's task progress, receive clarifying questions, and view results without switching applications. The agent operates in a secure, containerized environment, limiting its access to user-provided information only. Android Halo is designed to work with Google's Gemini and can also integrate third-party agents that meet specific requirements, in compliance with the EU's Digital Markets Act. Android 17 is expected to launch in August 2026 alongside the Pixel 11, which will be the first device to feature Halo. The availability of Halo on other devices, like the Samsung Galaxy S25+, is uncertain, and no pre-order windows for hardware with Halo have been announced in the US and UK.
