Repository pattern in Android. Why is it important

I remember the first time I was asked about repository pattern in android. why is it important 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 repository pattern in android. why is it important—the mistakes I made, the lessons I learned, and the best practices that'll help you ace your interviews and build better Android apps.
