Android Display notification in status bar without extensible view

I need help to do something. I am trying to display a notification in the Android status bar.

It will inform the user that synchronization with the server is in progress.

Now I use this code and it works fine:

NotificationCompat.Builder builder = new NotificationCompat.Builder(this) .setSmallIcon(android.R.drawable.stat_notify_sync).setWhen(System.currentTimeMillis()) .setAutoCancel(false).setOngoing(true); NotificationManager nm = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); Notification notif = builder.getNotification(); nm.notify(1, notif);

The only problem is that the view is created when the user expands the status bar. What I want to do is display only a small icon on the top line of the status bar with no content.

Does anyone know how to do this? Thanks in advance!

It's impossible.

The rationale is this: if the user looks at the status bar and sees the icon, she must somehow understand what this icon means. Therefore, the notification bar should have a line corresponding to each icon.

I suggest creating a notification explaining how you did this in your question that synchronization is in progress; this is a great opportunity to indicate which application is being synchronized (so if any problem or synchronization is performed forever, the user knows which application needs attention).

You can use this method to display a notification icon in the status bar.

  private void showNotification() { nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); // In this sample, we'll use the same text for the ticker and the // expanded notification // Set the icon, scrolling text and timestamp Notification notification = new Notification(R.drawable.ic_launcher, "Service Started", System.currentTimeMillis()); // The PendingIntent to launch our activity if the user selects this // notification PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0); // Set the info for the views that show in the notification panel. notification.setLatestEventInfo(this, getText(R.string.service_label), "Service Started", contentIntent); // Send the notification. // We use a layout id because it is a unique number. We use it later to // cancel. nm.notify(R.string.service_started, notification); }

Well, this is possible for InputMethodService, just use showStatusIcon (resource_name). But I think this is not a good idea for anything other than input services.

 Context context = TutListDownloaderService.this .getApplicationContext(); NotificationManager notificationManager = (NotificationManager) context .getSystemService(NOTIFICATION_SERVICE);

create notification:

 Notification updateComplete = new Notification(); updateComplete.icon = android.R.drawable.stat_notify_sync; updateComplete.tickerText = context.getText(R.string.notification_title); updateComplete.when = System.currentTimeMillis();

Create a pending object:

 Intent notificationIntent = new Intent(context,TutListActivity.class); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0); String contentTitle = context.getText(R.string.notification_title).toString(); String contentText; if (!result) { Log.w(DEBUG_TAG, "XML download and parse had errors"); contentText = context.getText(R.string.notification_info_fail).toString(); } else { contentText = context.getText( R.string.notification_info_success).toString(); } updateComplete.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

Finally, notify the user:

 notificationManager.notify(LIST_UPDATE_NOTIFICATION, updateComplete);
