What is modularization in Android development?

Modularization means splitting an app into smaller, independent parts called modules. Each module handles a specific feature or function, making the app easier to build and maintain.

Name two benefits of modularization in Android apps.

1. Faster build times because only changed modules need rebuilding.<br>2. Easier teamwork since developers can work on separate modules without conflicts.

What is a feature module in Android modularization?

A feature module is a self-contained part of the app that implements a specific feature, like login or profile. It can be developed and tested independently.

How does modularization improve app scalability?

By dividing the app into modules, you can add or update features without affecting the whole app. This makes it easier to grow and change the app over time.

What is the role of Gradle in Android modularization?

Gradle manages modules by defining dependencies and build rules. It helps build each module separately and combine them into the final app.

What does modularization help improve in Android apps?

A Build speed and code organization

B Only UI design

C Battery usage

D Screen resolution

Modularization improves build speed by building only changed modules and helps organize code better.

Which of these is a typical module in Android modularization?

A Feature module

B Color module

C Battery module

D Screen size module

Feature modules contain specific app features like login or settings.

How does modularization help teamwork?

A It slows down development

B Everyone edits the same file

C Developers work on separate modules without conflicts

D It removes the need for version control

Separate modules let developers work independently, reducing conflicts.

What tool manages module dependencies in Android projects?

A Git

B Firebase

C Android Studio Layout Editor

D Gradle

Gradle handles building modules and their dependencies.

Which is NOT a benefit of modularization?

A Faster build times

B More app crashes

C Better code reuse

D Easier testing

Modularization reduces crashes by isolating code, not increasing them.

Explain what modularization is and why it is useful in Android app development.

Think about how breaking a big task into smaller parts helps.

Describe how Gradle supports modularization in Android projects.

Gradle is like the app's builder and organizer.
