Project structure

The project consists of two modules: app and zegocall.

app

The app module implements the business and UI interaction logic, including login, contact list, calling, and more. The following shows the structure:

├── auth                ------ Tools for generating the token used for validating the login, room joining privileges 
├── http                ------ The logic for initiating network requests to business server
├── service                ------ Frontend service (to keep the app alive in the backend, prevent the app from being killed)
