Coroutines in Kotlin Android (how to run delay() or blocking routines)

delay.kt

import kotlinx.coroutines.*

// . A simple PAUSE. This example simulates a background task that "waits" before continuing.
fun main() = runBlocking {
    println("Task started...")
    delay(2000L) // Pause for 2 seconds (2000 milliseconds)
    println("Task finished after 2 seconds!")
}

// OR

// 2. Repeated Task (Polling/Clock)
// You can use delay() inside a loop to create a recurring event, like a timer or a network refresh.
@Composable
fun SplashScreen(onTimeout: () -> Unit) {
    LaunchedEffect(Unit) {
        delay(3000L) // Show splash for 3 seconds
        onTimeout()  // Navigate to Main Screen
    }
    // ... your Splash UI code ...
}

// OR

// 3. Simulating a Splash Screen (Android)
// Commonly used in a LaunchedEffect in Jetpack Compose to navigate after a set time.
val job = CoroutineScope(Dispatchers.Main).launch {
    while (isActive) {
        updateUI() // Your function to refresh the screen
        delay(5000L) // Wait 5 seconds before the next update
    }
}
