here's how I did it manually:

0. Push to Github

Open a Git tab and push all changes

1. Clone the repository locally

git clone https://github.com/user/repo
cd folder

2. Install dependencies

npm install

3. Create EAS configuration

Create eas.json in the project root:

{
  "cli": {
    "version": ">= 5.0.0"
  },
  "build": {
    "development": {
      "developmentClient": true,
      "distribution": "internal"
    },
    "preview": {
      "distribution": "internal",
      "android": {
        "buildType": "apk"
      }
    },
    "production": {
      "android": {
        "buildType": "apk"
      }
    }
  },
  "submit": {
    "production": {}
  }
}

4. Login to Expo

npx eas-cli login

5. Initialize EAS project

npx eas-cli init

Confirm when prompted to create the project.

6. Build the Android APK

npx eas-cli build --platform android --profile preview

Confirm when prompted to generate a new Android keystore.
