AsyncTask as kotlin coroutine

Question

Typical use for AsyncTask: I want to run a task in another thread and after that task is done, I want to perform some operation in my UI thread, namely hiding a progress bar

Answer 1

First, you have to run coroutine with launch(context), not with runBlocking: https://kotlinlang.org/docs/reference/coroutines/coroutine-context-and-dispatchers.html

Second, to get the effect of onPostExecute, you have to use

Activity.runOnUiThread(Runnable) or View.post(Runnable).
