How Do I Show An Icon In The Status Bar Without Showing A Notification In The Notification Drawer?

I want to show an icon in the status bar while my app is running but I don't want a notification to appear when the notification drawer is expanded, how can I do that?

Solution 1:

So you want to display something on the user device, that the user can't control or remove in any way nor know where it came from? Not possible...
