Doing a long running operation in a button handler in Android?

Question

Android

Hello!
I have a button which, when clicked, should perform a long running operation and the new received data is displayed and updated in a TextField. However, in practice, the application freezes. I tried to do Thread.sleep(1000), but the essence of this does not change.
Please advise what needs to be done to solve this problem.
Thank you.

Answer 1

Have you tried moving a long-running operation to a separate thread?

Answer 2

all long-running operations must be moved to a separate thread ala thread/asyncktask/service, etc., otherwise the application will stop responding to receive messages.
