🚀 Android Interview Questions Series Part 8: 2025🚀

Ques 1: What is LiveData, and how is it different from StateFlow?

Answer:

LiveData:
1. Designed to work with Android’s View components.
2. It is Lifecycle-aware, meaning it automatically cleans up when an activity is destroyed.

StateFlow:
1. Jetpack works better with Compose and coroutines.
2. It always stores the latest value and gives the last value even after a subscription.

Difference between the two:
1. LiveData is lifecycle-aware, StateFlow is not.
2. StateFlow retains the latest value, not LiveData.

Ques 2. Explain the difference betweenlaunch, async, and runBlockingin Kotlin coroutines.
Answer:
launch(Fire & Forget) 🔥
1. It starts a background task and does not return results.
2. It is non-blocking, meaning it allows the rest of the code to run.
✅ Use when: You do not want the result, just run the task.
🔹Example:

GlobalScope.launch {
    println("Launch: Background task running...")
}
