Can any one help how can I send a request in parallel using coroutines for example I am sending a list of images to the server in parallel or sequentially

There is one good thing to take into account though. If sending those does a data call you might have to change the actual thread those

async

blocks are being executed on. If you read this blog you will see why: https://kotlinexpertise.com/kotlin-coroutines-concurrency/. The

async { send(it) }

will be concurrently but not necessary in parallel.

@joeykaan Is there a difference between wrapping the whole thing within a

withContext(Dispatchers.Default)

vs

async(Dispatchers.Default)

?

As far as I can tell, no there is not. Wrapping it in withContext will run it on the Dispatchers.Default and async would do the same 🙂

Thanks for the answer
