I need some help with a progress dialog.

What I'm trying to do is use the progress dialog style spinner while the file is being read, when it finishes I want the dialog to dismiss.

As of right now it only loads after the file is found because of the loop. I don't know how to get it to load before the loop starts

 public void readFile() {

       pb.setMessage("Looking... after, view the tips in the menu bar :) ");
  pb.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    pb.setIndeterminate(true);
    pb.show();
     BufferedReader reader = null;
        try {
            reader = new BufferedReader(
        new InputStreamReader(getAssets().open(("account.txt"))));

        // do reading, usually loop until end of file reading  
            String mLine = reader.readLine();// reading each line.
      System.out.println("starting to read line in buffer");

    while (mLine != null) {
        //process line
        btn1.setEnabled(false); 

        if (mLine.toLowerCase().equals(theiraccount)) { // when an account is found stop reading

            checking =theiraccount; //trying to set vale of checking to theiraccount
               Log.d("if statement in mline",checking);
            reader.close();
            pb.dismiss();

             System.out.println("closed reader");
            mLine=null;// trying to stop the loop
            btn1.setEnabled(true);

            }//end if 
        else {

        }

        mLine = reader.readLine();
          System.out.println("cheking mLine"+ mLine);

    }   

    } catch (IOException e) {
        //log the exception
    } finally {
        if (reader != null) {
            try {
            reader.close();
        } catch (IOException e) {
            //log the exception
            Log.d("Catch buffer","i failed the catch in finally for reading lines");
        }
    }

}//end buffer reader

if (checking == theiraccount) {
    Toast.makeText(this,"im there",Toast.LENGTH_LONG).show();
    System.out.println("i just checked if its there");//another test
     btn1.setEnabled(true);
    tv1.setText("We found your account, click the menu for tips");
    pb.dismiss();
        } else {
    Toast.makeText(this,"im not there",Toast.LENGTH_LONG).show();
        btn1.setEnabled(true);
        tv1.setText("We cant find your      account, sorry dude");
    pb.dismiss();
    }
}
