【Android Studio/Kotlin】処理の実行時間を計測する方法！measureTimeMillis

import kotlinx.coroutines.*
import kotlin.system.measureTimeMillis

fun main() {
    val time = measureTimeMillis {
        runBlocking {
            val job = async { fetchDataFromRemote() }
            val remoteData = job.await()
            print("$remoteData")
        } 
    }
    print("Completed in $time ms")
}

suspend fun fetchDataFromRemote(): String {
    delay(2000)
    return "リモートサーバーからフェッチ"
}

リモートサーバーからフェッチ
Completed in 2102 ms
