App has two operational modes, “Realtime" and “Single Update”. “Realtime” allows app to always display to the user the current near by places based on his location, data should be seamlessly updated if user moved by 500 m from the location of last retrieved pl aces. “Single update” mode means the app is updated once in app is launched and doesn’t update again User should be able to switch between the two modes, default mode is “Realtime”. App should remember user choices for next launches
The app uses a Model-View-ViewModel (MVVM) architecture for the presentation layer. Every screen corresponds to a MVVM View. The View and ViewModel communicate using LiveData.
In the view model RxJava is used to handle the network request and map the response to a sutable representation that could be handled by the ui.
When the network response succeed it writes to a Room database, which exposes a LiveData connection to the view which means the app is offline ready. The bases of this architecture is https://github.com/android/architecture-components-samples
