i trying implement thread in application. working web service , fetching show results. time being showing progress dialog using thread. following thread implementation : 

final handler handler=new handler();       progdialog = progressdialog.show(departments.this.getparent(), "loading... ", "please wait....", true);       new thread(new runnable() {       @override      public void run() {       // todo auto-generated method stub       suid = downloaddata();   struid = suid.struid; dep = download(struid); departments = dep.departments; depid = dep.depid;  handler.post(new runnable() {   @override  public void run() {   // todo auto-generated method stub   progdialog.dismiss();  } });    }     }).start();
