performance wise, what is better: AsyncTask or simply create a runnable? [closed]

Question

I am currently working on an Android project which loads a lot of pictures onCreate. To make sure the UI doesn't get blocked I have the option to put it in a runnable or an AsyncTask. What is (performance wise) the better option or is it practically the same?

Answer 1

Yes it's more or less the same.AsyncTask is nothing else than an convenience-class for Runnable/Thread.

In my opinion you should use AsyncTask. It's kind of an android standard plus it takes the task away from you to check when the work is finished. You can easily make a callback in the onPostExecute or do whatever you want with the result. (Remeber that only doInBackGround runs in an own thread - the other methods run in the UI thread, so you can even add dialogs there and so on if you want.

Answer 2

If you attach your Runnable on a new Thread then practically both would do the same under the hood. However, it is more easier to follow AsyncTask life-cycle and its the recommended way of doing parallel things in android. Therefore, my suggestion is to go with AsyncTask.
