How to execute Async task repeatedly after fixed time intervals

Question

How to make Async task execute repeatedly after some time interval just like Timer...Actually I am developing an application that will download automatically all the latest unread greeting from the server and for that purpose I have to check for updates from server after some fixed time intervals....I know that can be easily done through timer but I want to use async task which I think is more efficient for android applications.

public void callAsynchronousTask() {     final Handler handler = new Handler();     Timer timer = new Timer();     TimerTask doAsynchronousTask = new TimerTask() {                @Override         public void run() {             handler.post(new Runnable() {                 public void run() {                            try {                         PerformBackgroundTask performBackgroundTask = new PerformBackgroundTask();                         // PerformBackgroundTask this class is the class that extends AsynchTask                          performBackgroundTask.execute();                     } catch (Exception e) {                         // TODO Auto-generated catch block                     }                 }             });         }     };     timer.schedule(doAsynchronousTask, 0, 50000); //execute in every 50000 ms }

  //Every 10000 ms           private void doSomethingRepeatedly() {       Timer timer = new Timer();       timer.scheduleAtFixedRate( new TimerTask() {             public void run() {                    try{                       new SendToServer().execute();                     }                   catch (Exception e) {                       // TODO: handle exception                   }               }             }, 0, 10000);                      }
