# Expo

This plugin is designed for use with Expo. Please ensure that you are using one of the following workflows:

* Bare Workflow
* Managed Workflow with EAS

You can build your project in the cloud using EAS Build or locally with the `expo prebuild` command.

#### Configuring Platform-Specific AdMob App IDs

If you are using **Bare Workflow**, you need to manually add the AdMob App IDs to the native configuration files, as described [here](/aatkit-react-native-integration/start/google-mobile-ads-sdk.md).

However, for Managed Workflow with EAS to specify separate AdMob App IDs for Android and iOS, you need to update your Expo configuration. This can be done in either `app.config.js` or `app.json` by adding the following entry under `plugins`, like:

```json
plugins: [
  [
    "@addapptr/react-native-aatkit",
    {
      "androidAdMobAppId": "ca-app-pub-000000000000000~0000000000",
      "iosAdMobAppId": "ca-app-pub-000000000000000~0000000000"
    }
  ]
]
```

This ensures that the correct AdMob App ID is used depending on the platform the app is running on.
