ProGuard/R8? How do you use it for app optimization

I remember the first time I was asked about proguard/r8? how do you use it for app optimization 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 proguard/r8? how do you use it for app optimization—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

ProGuard/R8: Code shrinking, obfuscation, and optimization tool for Android.

Features:

1. Code Shrinking: Removes unused code
2. Resource Shrinking: Removes unused resources
3. **Obfu...

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