Floating Notifications brings the usefulness of Facebook chat heads to every Android app that shoots out a notification. Get an email - receive a floating Gmail icon on the side of the screen begging for attention. Tapping that icon reveals the contents of the message. Double tapping dismisses the notification, but there's a catch - before now, removing the floating notification hasn't also removed it from the status bar. Thanks to the latest update, devices running Android 4.3 will sync these actions due to integration with the new Notification Listener Service.
Floating Notifications earned a place in our roundup of top apps from May even though it wasn't even in the Play Store yet. Well, now it is and it comes with a ton of improvements over the beta version from XDA.
The basic premise of Floating Notifications is that it displays a subset of your notifications in a floating icon on the screen. It's a little bit like Facebook's Chat Heads feature.
