}
 public void receiptRegisterDataReady(Object obj) {


       /// Getting Response In This Block Doing Some Manupilation And Dismiss progressBar...      
        progressBar.dismiss();

    }`

Thanks for any help

Although built in `onCreate`, the screen is not actually displayed there. `onCreate` queues up actions to complete later. You need to let `onCreate` finish as soon as possible. Move any longer-running processing to another lifecycle callback such as `onResume` and don't hang up in `onCreate`. Not sure if this is your issue, but I hope it helps. — Cheticamp, Mar 01 '17 at 12:48

You are doing too much work in the OnCreate main Thread. This is why it freezes your Android Application.

Do your Progress UI in the Main thread like so:

 @Override
protected void onCreate(Bundle savedInstanceState) {
     setContentView(R.layout.activity_receipt_register);

   progressBar = new ProgressDialog(this, "title", "loading");

    heavywork();

}

   public void heavywork()
{

//start a new thread to process job
     new Thread(new Runnable() {  
         @Override  
         public void run() { 
             // Do all the Data From Server code here ! 
          }  
      }).start();

}

This might help you: ProgressDialog in a separate thread
