You should write the part updating the progressbar as an AsyncTask to see the loading lively. You can also use Handlers.

this can help: http://developer.android.com/reference/android/os/AsyncTask.html

Use AsyncTask, it has helpful methods namely

      protected void onPreExecute(){
        //Show a dialog here
     }
      protected void onProgressUpdate(Integer... progress) {
         setProgressPercent(progress[0]);
     }

     protected void onPostExecute(Long result) {
         showDialog("Downloaded " + result + " bytes");
     }

You can publish your percentage progress in onProgressUpdate method and in onPostExcecute dismiss the dialog

you have to used the ProgressDialog: http://developer.android.com/reference/android/app/ProgressDialog.html

It can show a indeterminate progress bar or a percentage. To update the percentage bar, you'd possibly need to use the class AsyncTask. I put a link which shows the two classes working together: http://sites.google.com/site/androidhowto/how-to-1/asynctasks-with-progressdialogs

I'm adding a more useful link: http://www.codeproject.com/Articles/162201/Painless-AsyncTask-and-ProgressDialog-Usage
