Retrofit in Android. How do you set it up and use it

I remember the first time I was asked about retrofit in android. how do you set it up and use it 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 retrofit in android. how do you set it up and use it—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

Retrofit: Type-safe HTTP client for Android and Java.

Setup:

implementation 'com.squareup.retrofit2:retrofit:2.9.0'
implementation 'com.squareup.retrofit2:converter-gson:2.9.0'

...

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