java - Pause or sleep AsyncTask without affect to UI -

can sleep or stop asyctask's execution without affect ui? there way other creating new thread achieve (i sure doesn't affect ui though)?

explanation:

public class myasync extends asynctask<....>{   @override   ..doinbackground(){    //do      for(....){           //sleep asynctask             //i want delay loop         }      //do     }  } 

creating new thread isn't want follow:

//inside doinbackground() new thread(new runnable(){    @override    public run(){      for(..){        thread.sleep(1000);//sleeping 1 second      }   } }); //other parts 

p.s. using asynctask in service run in background every n seconds.

if call thread.sleep(1000) inside doinbackground() method, not affect ui since doinbackground() called on background thread.
