Just Conclusion of above video:: [For beginners only] there are basically two kind of execution 1. Sequential (Default) 2. Concurrent(achieved with async{} ) For instance if we have two function func1() & func2(), execution of func2() is dependent on func1() then in that case we can use default version of coroutine and if they are independent of each other then we can use concurrent with the help of async{} with the sequential execution we run the code sequentially so if func1() takes 5sec for execution and func2() takes 3 sec for execution then total elapsed time will be around 8 sec, however when this methods are independent and their results are not required for execution of other fun then in that case execution can be completed in 5 sec with the help of async(concurrent). Async vs launch: Async returns Deffered [Type:: calling function is returning] launch returns Job. await() -> methods are used to ensure the execution will go further until function is executed completely. [e.g func1().await()] We can also call async with LAZY pass below value in async constructor. val one = async(start = CoroutineStart.LAZY) { func1()) } one.start() // start the execution of func1 Reference link:: (Highly recommended: please watch this video before exploring below link) kotlinlang.org/docs/reference/coroutines/composing-suspending-functions.html

You are repeating a very incorrect statement that gets thrown around a lot with coroutines. All coroutines are sequential. What produces concurrent code are nested coroutines. Async does not produce concurrent code without nesting. It just returns the value. You decide how the code is blocked depending on where you put the .await() or .join() functions.

So I just watched the entire series (except android specific things because I don't make android apps) and I really helped a lot. I finally understood those thingies. I knew the async mechanics from other languages like Dart and a bit of JS but I had hard time mapping the Kotlin syntax to what was used to. This did really help.

I've read a whole bunch of blogs and posts and watched a ton of videos. This is the first thing that actually explains the difference between launch and async. Nice.

I'm in a fragment and after onCreate(), onCreateView() is called, the problem is that I need the data retrieved from the service in onCreate to use it in onCreateView, but what happens is that the code keeps going and crashes, the problem is that it has no data because is being obtained in the corrutine in onCreate, like your method. How can I wait for corrutines to retrieve data before continuing to onCreateView()? Hope I made myself clear, thank you!

I think the async will create 2 separate threads and wait for it, in that case what is the use of suspend? In first way coroutine scope will run in a single thread for both network calls?
