# Register the Android App with Catalyst

After you create the Catalyst project and the Android project, you must create a package for the Android app in Catalyst to register it, and download its unique configuration file.

This configuration file, `app\_configuration\_development.properties`, contains the definitions of the Catalyst project, the app client, and other OAuth authentication properties, that are auto-populated in it. You can view a complete list of the properties that this file defines from [this help section](https://docs.catalyst.zoho.com/en/sdk/android/v2/setup/#step-2-import-the-configuration-file-in-your-android-project).

> **Note:** Because we are working in the development sandbox with the Catalyst project, we will only be able to download the configuration file for the [development environment](https://docs.catalyst.zoho.com/en/deployment-and-billing/environments/introduction). If you have a project deployed to production, you will be able to access the same file with the production environment variables populated in it.

1. Click the Settings icon from your Catalyst console in your project and navigate to Developer Tools under Project Settings. Click the Android Tile.

2. You must enter the same package name that you entered in Android Studio while creating the project. Enter the following values and click **Create**.

Package name: **"com.catalyst.zcdrive"**

Redirect URL: **"home"**

The redirect URL defines the URL the user will be redirected to, after they login to the app.

![android-package](https://catalyst-docs-development.zohostratus.in/images/tutorials/zcdrive/android-package.webp)

The package will be created successfully.

![package-created](https://catalyst-docs-development.zohostratus.in/images/tutorials/zcdrive/package-created.webp)

You can click **Download** to download the configuration file to your local system.

The configuration file will be downloaded to your system with all the property definitions mentioned earlier. The _Mobile SDK_ section in _Developer Tools_ will display the details of the Android SDK package configured with this project.
