Google has released the stable version of Android Studio Otter 2 Feature Drop, the final major IDE update of 2025. This release consolidates months of performance improvements, new AI capabilities, and a far smarter integration with official documentation. The result: a more precise, consistent, and developer-aligned workflow.
More powerful Agent Mode: Gemini 3 and an official knowledge base
Access to Gemini 3 Pro Preview
Android Studio now supports Gemini 3 Pro Preview, Google’s top model for code assistance and agent-based workflows. Context handling and complex task planning are notably improved, especially in refactoring flows, code explanations, and Compose UI generation.
Google is rolling it out progressively for users of the default free model, with a context window of up to 1 million tokens. For longer sessions or higher limits, developers can integrate a Gemini API key or a Gemini Code Assist Enterprise plan.
An Agent Mode that queries real documentation
Traditional LLMs rely on frozen knowledge. To avoid outdated API info or gaps in best practices, Google introduces the Android Knowledge Base.
Agent Mode can now query verified and up-to-date documentation before responding, including:
- Android Developers
- Firebase
- Google Developers
- Kotlin Docs
This reduces errors, minimizes hallucinations, and improves accuracy when official information is required.
The update downloads automatically and works with any LLM configured in the IDE.
Backup and Sync: your Android Studio, identical on all machines
Otter 2 adds a native Backup and Sync system that synchronizes IDE preferences and configuration across devices via:
- a Google account, or
- a JetBrains account.
It can store keymaps, editor settings, system configuration, and other personal preferences. When installing Android Studio on another machine, the user simply chooses whether to download the existing setup or upload the local one to the cloud.
A highly requested feature for teams working across multiple environments.
Direct communications from the Android Studio team
A new option allows receiving notifications and emails directly from the IDE team: new features, updates, libraries, or important alerts. The option is available during login or in:
Settings > Tools > Google Accounts > Communications
IntelliJ IDEA 2025.2 improvements: performance and stability
This release includes everything new from the IntelliJ platform.
More stable, faster Kotlin K2
The K2 compiler integration continues to solidify:
• more stable code analysis
• new inspections
• improved reliability for Kotlin scripts
Faster terminal
The integrated terminal sees significant performance and rendering improvements, especially for Bash and Zsh, plus minor visual updates.
