First of all I added some format to your question. Now it's readable.

You should check the Reference: AsyncTask Reference[^] @ developer.android.com/reference

and take a look at the great tutorials of Lars Vogel for this:
Android Background Processing with Handlers and AsyncTask and Loaders - Tutorial[^] @ Vogella.com

Hello,

Create one class that extends AsyncTask like,

public class QuestionHelper extends AsyncTask<String, String, ArrayList<HashMap<String, String>>>

public QuestionHelper(Context ctx)
	{
		this.ctx = ctx;
	}

and then in other class or activity, go like this

ArrayList<HashMap<String, String>> QuestionsList = new QuestionHelper(getApplicationContext()).execute().get();;

how to get result back from asyncTask in main thread.
