Kotlin

Q1: What is a primary constructor in Kotlin? ☆☆

Answer: The primary constructor is part of the class header. Unlike Java, you don't need to declare a constructor in the body of the class. Here's an example:

kenandersen

// Random terminal tip #1

//You'll see this message if you git commit without a message (-m)
// You can get out of it with two steps:
// 1.a. Type a multi-line message to move foward with the commit.
// 1.b. Leave blank to abort the commit.
// 2. Hit "esc" then type ":wq" and hit enter to save your choice. Viola!

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.

// UPDATE: Everyone finding this gist via Google! 
// Modern kotlinx.coroutines has out-of-the-box support for asyncLazy with the following expression: 
// val myLazyValue = async(start = CoroutineStart.LAZY) { ... } 
// Use myLazyValue.await() when you need it

// ---------------- public api ----------------

public interface AsyncLazy<out T> {
    public suspend fun value(): T
    public fun isInitialized(): Boolean

Android Interview Questions

Q1: Explain activity lifecycle ☆☆

Answer: As a user navigates through, out of, and back to your app, the Activity instances in your app transition through different states in their lifecycle.

To navigate transitions between stages of the activity lifecycle, the Activity class provides a core set of six callbacks: onCreate(), onStart(), onResume(), onPause(), onStop(), and onDestroy(). The system invokes each of these callbacks as an activity enters a new state.

gmk57

/**
 * Starts collecting a flow when the lifecycle is started, and **cancels** the collection on stop.
 * This is different from `lifecycleScope.launchWhenStarted { flow.collect{...} }`, in which case
 * the coroutine is just suspended on stop.
 */
inline fun <reified T> Flow<T>.collectWhileStarted(
    lifecycleOwner: LifecycleOwner,
    noinline action: suspend (T) -> Unit
) {
    object : DefaultLifecycleObserver {
