Gemini in Android Studio's Agent Mode is designed to handle complex, multi-stage
development tasks that go beyond what you can experience by just chatting with
Gemini. You can describe a high-level goal, and the agent creates and
executes a plan, invoking the necessary [tools](https://developer.android.com/studio/gemini/agent-mode#how-it-works), making changes
across multiple files, and iteratively fixing bugs. This agent-assisted workflow
lets you tackle intricate challenges, accelerating your development
process.

## Get started

To get started in Agent Mode in Android Studio, follow these steps:

1. Click **Gemini** ![](https://developer.android.com/static/studio/images/gemini-icon.png) in the tool window bar. Sign in and onboard if you need to.
2. Select the **Agent** tab.
3. Describe the task you want the agent to perform.

1. Review and approve any changes as the agent works to accomplish the task.

1. Optional: To automatically approve changes, select **Agent options

   \> Auto-approve changes**.

## Use cases

Here are some examples of use cases that the agent can help you with:

- **Fix build errors.** When you ask the agent to fix a build error using a prompt like "Fix build errors in my project," it applies a recommended fix, builds the project to verify the solution, and iterates until the issue is resolved.

- **Add or update UI elements.** The agent can add or update UI elements. For example, ask the agent to "Make dark theme the default in user preferences" and it searches for the relevant files and suggests changes to accomplish the task. You can immediately preview the UI updates in the **Running devices** tool window.

- **Generate mock data.** When prototyping and testing your app, you can ask the agent to generate mock data instead of manually creating it. For example, when prompted to "Add two more sessions to the fake data," the agent finds the relevant file and adds two more events to the `mockSessions` list.

Some other prompts to try:

- "Write unit tests for \<class\> in \<module\>"
- "Generate documentation for the open file"
- "Change the app title from \<current name\> to \<new name\>"
- "Resolve the null pointer exception"
- "Refactor my code by moving the \<composable name\> composable to a new file. Verify that all imports are updated"
- "Add a new button to the app's home screen called 'Follow' that takes you to a list of topics"
- "In the \<composable name\> composable, reduce the padding of the \<modifier name\> modifier"
- "Create a share button to share to social media"

## How the agent works

In Agent Mode, your prompt is sent to the Gemini API with a list of *tools* that
are available. You can think of tools as skills: they include the ability to
search for files, read files, search the text within files, use any
[MCP servers](https://developer.android.com/studio/gemini/add-mcp-server) you have configured, and more.

When you give the agent a task, it creates a plan and determines which
tools are needed. Some of these tools might need you to grant permission before
the agent can use them. Once you grant permission, the agent uses the tool to
perform the necessary action and sends the result back to the Gemini API. Gemini
processes the result of the action and generates another response. This cycle of
action and evaluation continues until the task is complete.
