MVVM architecture in Android. What are the key components

I remember the first time I was asked about mvvm architecture in android. what are the key components in an interview. I thought I knew it well—until the interviewer started digging deeper.

"What happens when..." they asked. "How would you handle..." they probed.

That's when I realized: knowing the basics isn't enough. You need to understand the why, the when, and the how.

Let me share everything I've learned about mvvm architecture in android. what are the key components—the mistakes I made, the lessons I learned, and the best practices that'll help you ace your interviews and build better Android apps.

Understanding the Basics

MVVM (Model-View-ViewModel): An architectural pattern that separates UI logic from business logic.

Components:

1. Model: Data layer (database, network, repositories)
2. View: UI comp...

But there's so much more to it than that.
