Create a asyntask and put your time consuming tasks

 public void doBackup(View view) throws IOException{
        ProgressDialog pd = new ProgressDialog(this);
       pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        pd.setMessage("Running backup. Do not unplug drive");
       pd.setIndeterminate(true);
       pd.setCancelable(false);
        pd.show();
//create asyntask here
//Put below code in doInBackground mathod
        File source = new File("/mnt/extSdCard/DirectEnquiries"); 
        File dest = new File("/mnt/UsbDriveA/Backup");
        copyDirectory(source, dest);
//put this code in onPostExecute Method.
        pd.dismiss();
    }

You will get number of samples of Asyntask.
