You can use AsyncTask for this

    public class MyAsyncTask extends AsyncTask<Void, Integer, Boolean>
    {

        @Override
        protected void onPreExecute() {
            // TODO Auto-generated method stub
            super.onPreExecute();
    /** do your initialization here like setting up porgress bar or some other 

variable it's up to you*/
        }


        @Override
        protected Boolean doInBackground(Void... params) {
            //do your 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 with you alertdialog here
            if(result)
                     {
                      //do something with our alert dialog
                     }
                     else
                     {
                      //do something with your alert dialoge
                     }
            super.onPostExecute(result);
        }




    }

Updating the progress by passing the percentage value via handler to asycn task. Once it is completed show the alert dialog in postExecute().
