Weather application

The project demonstrates latest android technologies.

Architecture

The architecture of the app is based on the concept of Clean Architecture as introducted from Robert C. Martin.(Uncle Bob)

Why Clean Architecture?

• Separation of Concerns — Separation of code in different modules or sections with specific responsibilities making it easier for maintenance and further modification.
• Loose coupling — Add flexibility to the code without breaking changes.
• Can be tested easily.

Layers

The layers used

App(presentation) layer

Has UI functionality using activities,fragments, views etc. Communicates with both data and domain layers

Domain layer

Contains business logic and does not communicate with no other layer.

Data layer

Provides data to the app using network, databases etc Communicates with domain layer

Other components

Other components are

• Use Cases (or interactors). Each individual functionality or business logic unit can be called a use case, like fetching data from the network. The are created to domain layer and presentation layer use the to communicate with data layer.
• Repositories. Interfaces that are created into domain layer and implemented from data layer.

Technologies used

• MVVM The presentation layer is based on it.
• View binding
• Room for database persistance
• Hilt for depentancy injection
• Coroutines

Other libraries

• okhttp for networking
• glide for images
