Why architecture scales codebases in Android Kotlin - Quick Recap

Recall & Review

beginner

What is the main purpose of using architecture in Android app development?

Architecture helps organize code so it is easier to understand, maintain, and grow as the app gets bigger.

beginner

How does architecture help when multiple developers work on the same codebase?

It creates clear rules and separation of concerns, so developers can work on different parts without conflicts or confusion.

beginner

What does 'separation of concerns' mean in app architecture?

It means dividing the app into parts where each part has one clear job, like UI, data, or business logic.

intermediate

Why does a well-architected codebase reduce bugs when scaling?

Because each part is independent and testable, so problems are easier to find and fix without breaking other parts.

beginner

Name one popular architecture pattern used in Android development.

Model-View-ViewModel (MVVM) is a popular pattern that separates UI, data, and logic clearly.

What is a key benefit of using architecture in a growing Android app?

A Makes the app run faster

B Makes the code easier to maintain and extend

C Removes the need for testing

D Allows using more colors in UI

Architecture organizes code to keep it manageable as the app grows.

Which of these best describes 'separation of concerns'?

A Mixing UI and data code together

B Ignoring code structure

C Writing all code in one file

D Dividing code so each part has a single responsibility

Separation of concerns means each part of the app has one clear job.

How does architecture help teams work better together?

A By creating clear roles and boundaries in code

B By making code confusing

C By forcing everyone to write the same code

D By removing comments

Clear code boundaries help team members work on different parts without conflicts.

Which architecture pattern is commonly used in Android apps?

A MVC

B Singleton

C MVVM

D Factory

MVVM separates UI, data, and logic, making code easier to manage.

Why does a well-architected app have fewer bugs when it grows?

A Because code is tested and parts are independent

B Because it uses more colors

C Because it has fewer lines of code

D Because it runs on faster devices

Independent parts are easier to test and fix, reducing bugs.
