Android Studio Quail 4: AI skills and Gemma 4 integrated
Google has released Android Studio Quail 4 as the final stable version of the Quail series, bringing significant AI-powered enhancements to its integrated development environment (IDE). The release bundles 23 curated Android skills—modular, AI-optimized instructions built on the open agent skills specification—directly into the IDE, enabling the built-in AI agent to automatically invoke domain-specific knowledge for complex Android workflows. It also natively integrates Gemma 4, Google's most powerful open model, for private, secure, and offline AI coding assistance, including a bundled inference engine and one-click model downloads. Additional improvements include parallel agent UX notifications, hyperlinked code symbols, a unified summary of changes, and collapsible reasoning for planning. Developers can access premium AI capabilities via API keys (including Anthropic or OpenAI models), Google AI Pro/Ultra plans, or Gemini Enterprise through Google Cloud.
Google's stable release of Android Studio Quail 4 introduces significant AI-driven developer tools, including bundled Android skills and on-device Gemma 4 inference, which will accelerate AI adoption in app development across the industry.

Gemma 4 Enables Agentic AI on Consumer Devices
This recap of The Agent Factory episode with Omar Sanseviero (Google DeepMind) reviews the release and capabilities of Gemma 4, an open model family optimized for on-device and local deployment. Since launching last month, Gemma 4 has recorded over 50 million downloads. The family includes small edge-optimized variants (E2B & E4B), a 31B dense model, and a 26B Mixture-of-Experts (MoE) model. Google DeepMind moved Gemma 4 to an Apache 2 license to enable commercial use and local fine-tuning in regulated or air-gapped environments. Demonstrations highlighted offline agentic workflows (local food-tour agent, Android skill selection), autonomous Python execution including a physics simulation, and architecture choices such as per-layer embeddings and variable-aspect-ratio vision support.
Leverage Android skills and Gemma 4 in Android Studio Quail 4
This is the final stable release for Android Studio Quail. The new features in Android Studio enable you to build premium apps with AI efficiently and effectively.
Gemma 4 12B, AI Copilot Selection, AI‑Optimized Docs
This roundup covers three developer-focused AI items: Google announced Gemma 4 12B, a new foundational multimodal model described as a "unified, encoder-free" architecture intended to handle text and images more efficiently and with lower inference cost; an InfoQ presentation by Sepehr Khosravi that provides guidance on evaluating and selecting AI copilots to boost developer productivity and integrate with toolchains; and a Dev.to article discussing techniques to author documentation that serves both human readers and AI assistants (notably Retrieval-Augmented Generation systems) through semantic markup and structured metadata. The post is aimed at developers building AI-enabled workflows and emphasizes practical considerations for model choice, tooling integration, and data preparation for RAG-style assistants.
