Android 17 Is Here: Everything Developers Need to Know
Quote:
"Google officially released Android 17 on June 16, 2026, making it available on most supported Pixel devices with partner OEMs to follow in the coming months. This is not a minor version bump. Android 17 marks a fundamental shift — Google is moving Android from an operating system to what they're calling an "intelligence system," with deep AI agent integration, mandatory adaptive layouts, strict memory enforcement, and a decisive declaration that Jetpack Compose is now the only path forward for Android UI."
