I have seen examples of using GlobalScope.launch and runBlocking to create coroutines. How i can create coroutines without using the above two options? Using runBlocking as coroutine builder launches coroutines on a single thread, but i don't want to that. And GlobalScope launches in the root scope and has to be taken care of. What other options i have?

Start your program in suspend fun main (yes, main can be suspend) and then just use coroutineScope {...} in your suspend functions 🙂

runBlocking(Dispatchers.Default)

and it is not single threaded anymore. Or you can do a context switch inside (

withContext(Dispatchers....)

)

Create your own CoroutineScope.... Eg.

val scope = CoroutineScope(<http://Dispatchers.IO|Dispatchers.IO>)

☝️ creating your own scope is probably the most flexible, just remember to cancel it when you’re done
