Meanwhile, Agent Mode can take advantage of Gemini 2.5 Pro’s 1 million token context window if you enter your Gemini API key: File (Android Studio on macOS) > Settings > Tools > Gemini.

Agent Mode can be used with Gemini's free tier, which supports a limited context window. Alternatively, engineers can use a one-million-token window by upgrading to Gemini 2.5 Pro.

The new feature, called Agent Mode, is part of Gemini in Android Studio, the company’s development environment for designing, building and testing applications for Android smartphones.
