What the quiz covers
The quiz covers modern Android development with Kotlin, Jetpack libraries and Compose, as asked in Android developer interviews. The 25 questions are grouped into 13 areas, shown above each question: Basics, Lifecycle, Architecture, Components, Background, UI, Resources, Data, Networking, Threading, Permissions, Tooling, Publishing.
A sample question explained
"What happens to an activity on screen rotation by default?" The answer is It's destroyed and recreated. Keep state in a ViewModel. This is why UI state belongs in a ViewModel and not in the activity's fields.
More questions you'll meet
A few of the other Android development questions in the bank:
- Which method runs when the activity is no longer visible?
- What is an Intent?
- Which component runs long tasks without a UI?
- In Compose, what does remember { mutableStateOf(0) } do?
- What is RecyclerView for?
- Which library is the recommended SQLite abstraction?
- Why mustn't you run network calls on the main thread?
Study tips
- Build a small app with a list, a detail screen and a ViewModel while revising.
- Learn the lifecycle order: onCreate, onStart, onResume, then onPause, onStop, onDestroy.
- Aim for at least 20 out of 25 on two separate attempts before you treat Android development as revised; one lucky score can hide gaps.
Questions and options are shuffled on each attempt, so a retake is a fresh test. The Android development questions were written by Uncodemy for practice; they aren't copied from any exam or company test.
