Android Interview Questions & Answers
Most interview prep stops at surface-level answers. This book doesn't. Every question is taken apart, the concept, the internals, the trade-offs, so you walk into interviews knowing the why, not just the what.
Covers Android Framework, Jetpack Compose internals, UI architecture, and Jetpack libraries, built from patterns seen across hundreds of real interview sessions.
