Android Studio for Platform (ASfP) helps you set up your development environment for the[Android Open Source Project (AOSP)](https://source.android.com/). This page explains how to start a new project or import an existing one.

## Create a new project

1. If you don't have a project open, click**New Project** on the Welcome screen.![ASfP Welcome Screen showing New Project option](https://developer.android.com/studio/platform/images/welcome_screen.png)

2. If you already have a project open, select**ASfP \> Project \> New Project**from the menu.

3. Fill in the project configuration details in the wizard:![ASfP New Project configuration wizard screen](https://developer.android.com/studio/platform/images/finish_project_import_screen.png)

   - **Module paths:** Specify the absolute path to the root of your AOSP source code checkout (for example,`/path/to/aosp`).
   - **Lunch target:** Enter the lunch target you use for building (for example,`aosp_arm64-eng`).
   - **Project name:**Give your project a descriptive name.
   - **Directories / modules:** List the initial directories or modules you want to include in your project, separated by commas. These should be relative paths from the repository root (for example,`frameworks/base,
     packages/apps/Settings`). You can add more or refine this selection later.
4. Click**Finish** . ASfP creates the project structure and the`.asfp-project`configuration file.

## Configure and customize your project

After the initial project setup, you can further customize your project by editing the`.asfp-project`file located in the project root. This file lets you:

- Add or remove directories and modules.
- Enable support for other languages like Rust or C++.
- Configure build flags and environment variables.
- Specify test sources.

For detailed information on all configuration options, see the[Projects overview](https://developer.android.com/studio/platform/projects). After editing`.asfp-project`, you'll need to sync the project for the changes to take effect.

## Import an existing project

ASfP doesn't have a separate "import" action. To open an existing ASfP project configuration:

1. Select**ASfP \> Project \> New Project**.
2. In the**Project Name** field, navigate to and select the directory containing the existing`.asfp-project`file you want to open. The fields in the wizard will populate based on the selected`.asfp-project`file.
3. Click**Finish**. ASfP opens and indexes the project.
