How to wait for an asynchronous method to execute?

Question

Android

Hey!
The situation is as follows - I have a certain API on Kotlin, which has a method that I really need. This method, as I understand it, has a handler and I get its result asynchronously and can only execute the code in the received onSuccess callback. But I need to get the results of this method synchronously.
How can this be done?

Answer 1

Change the model to synchronous, obviously.

Answer 2

I get its result asynchronously and can only execute the code in the received onSuccess callback.

If you make the method synchronous, the application may "hang", because it is not known how long the request will be processed.
Better rewrite under asynchronous.
