Question

I\'m very new to programming and I have some doubts.

I have a AsyncTask which is I call as RunInBackGround.

and I start this proc

Answer 1

wait until this call is finish its executing

You will need to call AsyncTask.get() method for getting result back and make wait until doInBackground execution is not complete. but this will freeze Main UI thread if you not call get method inside a Thread.

To get result back in UI Thread start AsyncTask as :

String str_result= new RunInBackGround().execute().get();
