This is how I did this so that only one progress dialog can be open at a time  Based off of the answer from Suraj Bajaj  private ProgressDialog progress     public void showLoadingDialog          if  progress    null            progress   new ProgressDialog this           progress setTitle getString R string loading title            progress setMessage getString R string loading message              progress show       public void dismissLoadingDialog          if  progress    null  amp  amp  progress isShowing              progress dismiss              I also had to use  protected void onResume         dismissLoadingDialog        super onResume

Actually if you are waiting for response from a server it should be done programatically  You may create a progress dialog and dismiss it  but then again that is not  the android way    Currently the recommended method is to use a DialogFragment    public class MySpinnerDialog extends DialogFragment        public MySpinnerDialog                use empty constructors  If something is needed use onCreate s             Override     public Dialog onCreateDialog final Bundle savedInstanceState              dialog   new ProgressDialog getActivity             this setStyle STYLE NO TITLE  getTheme        You can use styles or inflate a view          dialog setMessage  Spinning         set your messages if not inflated from XML           dialog setCancelable false              return  dialog            Then in your activity you set your Fragment manager and show the dialog once the wait for the server started   FragmentManager fm   getSupportFragmentManager    MySpinnerDialog myInstance   new MySpinnerDialog      myInstance show fm   some tag      Once your server has responded complete you will dismiss it   myInstance dismiss     Remember that the progressdialog is a spinner or a progressbar depending on the attributes  read more on the api guide
