Handler vs AsyncTask

Question

I\'m confused as to when one would choose AsyncTask over a Handler. Say I have some code I want to run every n seconds which will update the UI. Why would I choose one ove

Answer 1

They are best interview question which is asked. AsyncTask - They are used to offload of UI thread and do tasks in background. Handlers - Android dosent have direct way of communication between UI and background thread. Handlers must be used to send message or runnable through the message queue.

So AsyncTasks are used where tasks are needed to be executed in background and Handlers are used for communication between a UI and Background Thread.
