アプリケーションのロード中にフリーズします。通知なしでファイルをダウンロードすると、正しく実行されます。何が問題なのですか?

        protected void onProgressUpdate(final Integer... values) {
                       new Thread(new Runnable() {
                            public void run() {

                                    mHandler.post(new Runnable() {
                                        public void run() {
                                             int progress=(int) ((values[0] / (float) values[1]) * 100);
                                                Integer textProgress=new Integer(progress);
                                               notification.contentView.setProgressBar(R.id.progressBar1, 100, progress, false);
                                               notification.contentView.setTextViewText(R.id.progress, textProgress.toString()+"%");
                                               myNotificationManager.notify(NOTIFY_ID, notification);

実際には、スレッドとランナブルのすべてのネストは必要ありません。これがサブクラスにあると仮定して、これをAsyncTask使用します。

protected void onProgressUpdate(final Integer... values) {
   int progress=(int) ((values[0] / (float) values[1]) * 100);
   Integer textProgress=new Integer(progress);
   notification.contentView.setProgressBar(R.id.progressBar1, 100, progress, false);
   notification.contentView.setTextViewText(R.id.progress, textProgress.toString()+"%");
   myNotificationManager.notify(NOTIFY_ID, notification);
}

onProgressUpdate()メイン（UI）スレッドで呼び出されるため、UI操作を直接実行しても安全です。
