Can anyone give me a clear description of what is AsyncCallBack? Does it exist in the latest android version? Because I am directed to AsyncTask when I search for AsyncCallBack…. Are these both same? Does anyone have an example?
Thanks in advance.
There is no class named AsyncCallback in android. I think what you are looking for is AsyncTask which is a way to run a piece of code on another Thread so the UI won’t be blocked, and receive it’s results on the UI thread. For example, say you want to talk to a server on the internet in response to the user clicking something in the UI, then receive some result from the server, and update the UI. AsyncTask makes doing this very easy compared to doing regular threading code because threading lifecycle and communication back to the UI thread is handled for you. As a bonus there is also support for canceling a background task, but you have to write the code to handle it when cancel is called. It doesn’t do it without some work on your side.
