Hello @wade-liwei. Unfortunately, right now Mooncake requires a google-play-services.json file in order to work properly. This is due to the fact that we're using the Firebase Cloud Messaging service to send to the application push notifications.

In order to solve your issue you can:

1. Setup a free Firebase project using the Firebase Cloud Console.
2. Add an Android app to your project.
3. Download the generated google-services.json file.
4. Place such file inside the android/app folder of the Mooncake project.

Once you have done so, you will be able to run the project properly.
