you can use asynctask this

    public class myasynctask extends asynctask<void, integer, boolean>     {          @override         protected void onpreexecute() {             // todo auto-generated method stub             super.onpreexecute();     /** initialization here setting porgress bar or other   variable it's you*/         }           @override         protected boolean doinbackground(void... params) {             //do work here                          //update progress bar                        publishprogress(total_progress);             return flag;  //return true or false          }          @override         protected void onprogressupdate(integer... values) {              super.onprogressupdate(values);                      //set progress here                      progressbar.setprogress(values[0])         }          @override         protected void onpostexecute(boolean result) {                   //deal alertdialog here             if(result)                      {                       //do our alert dialog                      }                      else                      {                       //do alert dialoge                      }             super.onpostexecute(result);         }         }
