Implementation

Data layer

The database is created using Room and has two entities: City and Forecast. Room generates the corresponding SQLite table at runtime.

Presentation layer

The app has a Main Activity and two Fragments.

• The fist fragment displays the a list of cities where the user can add them on the searchBar using the Google API.
• The second fragment displays a city and the forecast for the next five days.

The Activity works with a ViewModel to do the following:

• subscribe to the emissions of the user name and update the UI every time there is a new City emitted
• notify the ViewModel when the "Update" button is pressed and pass a City with update values.

The ViewModel gets the source from the Repository class

Room guarantees that the observable query will be triggered on a background thread.

This project shows how to use view bindings in an activity and in fragments. InflateFragment uses the inflate() API and BindFragment shows the less common bind() API.
