Android Interview Prep

Android Interview Prep covers the topics that show up in real Android interviews, from Activity lifecycle and Intents to Coroutines, Jetpack Compose, and Hilt. Content is organized into three levels so you can start with the
fundamentals and work your way up to advanced topics at your own pace.

What's inside:

Terms — clear definitions for the core Android concepts, written the way they come up in interviews, not just what the docs say.

Interview Q&As — common technical questions with full answers covering the details interviewers actually want to hear.

Flashcards — quick-fire review of the most important facts and distinctions, useful for drilling topics you want to lock in.

Tips — practical advice on how to study, what to prioritize, and how to use AI tools without leaning on them as a crutch.

Three levels of content:

Level 1 covers the Android foundations every developer needs cold: the Activity lifecycle, Intents, Fragments, Context, RecyclerView, and the Manifest.

Level 2 covers the modern Jetpack stack: MVVM, Kotlin Coroutines, Flow, Room, Navigation, and Hilt.

Level 3 covers advanced topics: Binder IPC, ProGuard/R8, process death, Compose recomposition, offline-first architecture, and on-device AI with ML Kit.

Track your progress through each level as you go. Whether you have an interview next week or want to fill in gaps in your Android knowledge, this app gives you a structured way to review what matters.
