Show ProgressBar in Notification Area like Google does when downloading from Android market
When you download from the Market you get informed about the progress in the notification area.
That's a really nice feature, which you may want for your own download or processing progress. I will show you the basics of generating such a Notification. All you need to do is add it to your code.
I included a screenshot. You can find the code at github.
First of all, you need your Notification object:
- // configure the notification
- final Notification notification = new Notification(R.drawable.icon, "simulating a download", System
- .currentTimeMillis());
- notification.flags = notification.flags | Notification.FLAG_ONGOING_EVENT;
- notification.contentView = new RemoteViews(getApplicationContext().getPackageName(), R.layout.download_progress);
- notification.contentIntent = pendingIntent;
- notification.contentView.setImageViewResource(R.id.status_icon, R.drawable.ic_menu_save);
- notification.contentView.setTextViewText(R.id.status_text, "simulation in progress");
- notification.contentView.setProgressBar(R.id.status_progress, 100, progress, false);
then add it to the NotificationManager
- final NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(
- getApplicationContext().NOTIFICATION_SERVICE);
- notificationManager.notify(42, notification);
in your Thread call the NotificationManager regularly, after you updated your notification with new values:
- notification.contentView.setProgressBar(R.id.status_progress, 100, progress, false);
- // inform the progress bar of updates in progress
- notificationManager.notify(42, notification);
The XML and the full example, ready to run, can be found on github.

The USB notification text and icon are much more darker.
How can I set the same look and feel?
Thanks.
