Hi! Can someone help me with this? Is there a simple method to transform the following

responseBody =  myTask.get();

into an async callback?

You could try #coroutines, see the callback into coroutines section here https://github.com/Kotlin/kotlin-coroutines/blob/master/kotlin-coroutines-informal.md

Thank you very much gor your response. Sorry I've seen now b/c I didn't get notified I will study your link. Before that, yes the problem is where the get is located in the code. It's inside a method returning an array which in turn is wrapped in a void event handler, more or less. So now it works but gui freezes that's why I'd like to improve but I'm afraid it would impact a lot of code. Actually I think I have to use onPostExecute AsyncTask in this specific case. Thanks again for your replies!!
