مشکل نمایش نوتیفیکیشن در اندروید 2.2

زمانی که برنامه رو روی اندروید 2.2 اجرا می کنم با ارور زیر مواجه میشم در صورتی که 4.0.3 این مشکل وجود ندارد

 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        final int notifyID = 1;
        final NotificationManager mNotifyManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        final Builder mBuilder = new NotificationCompat.Builder(this);
        mBuilder.setContentTitle("Picture Download")
                .setContentText("Download in progress")
                .setSmallIcon(R.drawable.ic_launcher).setAutoCancel(true);
        // Start a lengthy operation in a background thread
        new Thread(
                new Runnable() {

                    @Override
                    public void run() {
                        int incr;
                        // Do the "lengthy" operation 20 times
                        for (incr = 0; incr <= 100; incr += 5) {
                            // Sets the progress indicator to a max value, the
                            // current completion percentage, and "determinate"
                            // state
                            mBuilder.setProgress(100, incr, false);
                            // Displays the progress bar for the first time.
                            mNotifyManager.notify(1, mBuilder.build());
                            // Sleeps the thread, simulating an operation
                            mBuilder.setOngoing(true);

                            // that takes time
                            try {
                                // Sleep for 5 seconds
                                Thread.sleep(500);
                            }
                            catch (InterruptedException e) {}
                        }
                        // When the loop is finished, updates the notification
                        mBuilder.setContentText("Download complete")
                                // Removes the progress bar
                                .setProgress(0, 0, false).setOngoing(false);
                        mNotifyManager.cancel(notifyID);
                        mNotifyManager.notify(notifyID, mBuilder.build());
                    }
                }
        // Starts the thread by calling the run() method in its Runnable
        ).start();
    }
