What is domain layer in Android?
The Domain layer interacts with the Data and Feature (presentation) layer using interfaces and interactors. It is also completely independent and can be tested regardless of external components. Each domain layer has a unique use case, repository and business model.
Why Mvvm is better than MVC?
MVVM with Data Binding on Android has the benefits of easier testing and modularity, while also reducing the amount of glue code that we have to write to connect the view + model. Let’s examine the parts of MVVM.
Is Mvvm clean architecture?
Separating responsibilities becomes hard. MVVM with Clean Architecture is pretty good in such cases. … But since Android Architecture Components already provides a built-in ViewModel class, we are going with MVVM over MVP—no MVVM framework required!
What is a domain layer?
The domain layer is a collection of entity objects and related business logic that is designed to represent the enterprise business model. The major scope of this layer is to create a standardized and federated set of objects, that could be potentially reused within different projects.

Which of the following is an advantage of MVVM Architecture?
Migrating to MVVM offers several benefits, including: Separation of concerns – Typically, there is a connection between the user interface and application logic, resulting in change-resistant, brittle code. … Eliminates the need for application redesign – User interfaces become outdated.
Is it possible activity without UI in Android?
The answer is yes it’s possible. Activities don’t have to have a UI. It’s mentioned in the documentation, e.g.: An activity is a single, focused thing that the user can do.
What is Android ViewGroup?
The ViewGroup class is a subclass of the View class. ViewGroup instances work as containers for View instances to group View instances together. Android contains the following commonly used ViewGroup subclasses: LinearLayout.
What is clean code architecture?
Clean architecture is a software design philosophy that separates the elements of a design into ring levels. The main rule of clean architecture is that code dependencies can only come from the outer levels inward. Code on the inner layers can have no knowledge of functions on the outer layers.

Is repository part of domain model?
Yes, repository implementations can definitely be a part of your domain model. In Domain Driven Design, for instance, the main objective when implementing a repository is to focus on the the perspective of the code that consumes the repository, not the code in the repository itself.
What is an interface in Android?
An interface is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface. An interface is not a class. … A class describes the attributes and behaviors of an object. An interface contains behaviors that a class implements.
