{ "item_title" : "Mastering Android System Design", "item_author" : [" Sivavishnu R "], "item_description" : "Most Android system design prep treats the phone like a small server: draw some boxes, mention a database, call it done. That falls apart in the interview room, because Android isn't a server with a smaller screen - it's a runtime that freezes your work in Doze, kills your process without warning, and still expects the save button to work. Interviewers know this. This book is built around that reality.It starts from the OS constraints that shape every real design decision - Binder IPC, the ART garbage collector, process death, background execution limits - before moving through the modern Jetpack and Kotlin toolchain (Compose, coroutines, Room, WorkManager, Paging 3) that senior engineers are expected to use fluently, not just recite.A dedicated interview framework - Clarify, Rough HLD, Deep Dive, Discuss Trade-offs, Summarize (CRDDS) - turns it depends into a structured, defensible answer, with guidance on clarifying questions, HLD/LLD boundaries, and the trade-off language that separates mid-level answers from senior ones.The back half works through thirteen full case studies - messaging, social feeds, media sharing, ride-hailing, streaming, food delivery, e-commerce, trading, travel booking, maps, fitness tracking, collaborative editing, and payments - each carried end to end through API design, caching strategy, real-time behavior, offline sync, security, and the Android-specific edge cases that trip candidates up when an interviewer pushes.Structured as a 37-chapter roadmap with a glossary, a 50+ question interview bank, and a suggested reading path for every timeline, this book is for the Android engineer who wants to walk into the room reasoning like the system's designer, not its user.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/819/206/9798192064702_b.jpg", "price_data" : { "retail_price" : "34.99", "online_price" : "34.99", "our_price" : "34.99", "club_price" : "34.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
