Tech and Architecture:

• This application takes advantage of MVVM architecture
• Activity, ViewModel, Repository, LiveData, ObservableFields, DataBinding are the basic building blocks of this architecture
• All the UI related work like showing Toast, starting a new activity, showing the progress bar, etc is done in the Activity.
• Business logic is written in the ViewModel. Also the observable fields are present in the ViewModel which are observed from the XML when we use data binding.
• All API and DB calls happen from within the repository.
• It's a 1 way reference flow from Activity -> View Model -> Repository. For ViewModel/Repository to communicate back in the chain we use live data which is observed by the concerned entity.
• We have used Java as the primary programming language
• Constraint Layout has been used to design the UI

Libraries:

Apart from Gson(), no other 3rd party library has been used. Everything is built on top of the System APIs
