What the book gives you
108 interview questions, 162 extra practical questions, and 50+ pro tips. The goal is to understand Android concepts deeply, not just memorize answers. It helps you sharpen your thinking and prepare for real-world technical challenges. Absolutely worth a read!

New project: Compose Stability Inference
This is Jaewoong’s latest deep dive into how the Compose compiler determines type stability to optimize recomposition. Repo: https://github.com/skydoves/compose-stability-inference

This one is an absolutely masterpiece full of knowledge, I promise.

Highlights at a glance

• Full stability type system

• Decision trees and inference algorithms used by the compiler

• Bitmask encoding and $stable field generation for generics

• Compiler phases that influence skipping and performance

• Reports, configuration files, and annotations to inspect and control stability

• Case studies for data classes, generics, interfaces, and inheritance

• @Stable vs @Immutable explained with real performance implications

If you want to level up both your Android interview prep and Compose performance knowledge, grab the discount and give the repo a ⭐

This post is a great chance to expand on some of the class stability inference topics we discussed in the Jetpack Compose Internals book.

Enjoy these awesome resources!
