You may want to check new features of Android 5.0 APIs for possible options that you can do.

As discussed in Notifications , you can control the visibility level of notifications by calling setVisibility() and specify one of these values:

• VISIBILITY_PRIVATE : Shows basic information, such as the notification's icon, but hides the notification's full content.
• VISIBILITY_PUBLIC : Shows the notification's full content.
• VISIBILITY_SECRET : Shows nothing, excluding even the notification's icon.

As for badge icons, you can use the new LauncherApps class to get a list of launchable activities for the current user and any associated managed profiles. Your Launcher can make the managed apps visually prominent by appending a work badge to the icon drawable. To retrieve the badged icon, call getUserBadgedIcon() .

Lastly, for floating notifications, you may call Notification.Builder method when you construct the notification and setPriority() . Notifications with the priority field set to PRIORITY_MAX or PRIORITY_HIGH appear in a small floating window if the notification also has sound or vibration.

Hope that helps!
