[Android/Kotlin] Coroutine - suspend가 redundant?

Android Studio에서 corotine을 쓸때

 

 

Update

In the recent releases of Kotlin Coroutines, I notice if a method doesn't contain any coroutines code(like launch, async, etc), the compiler complains This inspection reports a suspend modifier as redundant if no other suspend functions are called inside. So I assume that suspend should be only used when it's a must.

An advice from Google
