The best way of multi tasking manage in Android is using launch Google Now gesture.
It no need run service in background and you can launch it every where you want.
So this is why I write DOCKAT!
Dockat is the most convenient and intuitive way to switch between applications and adjust system settings for Android 4.1 and up.
Whether you're in the browser, at a home screen, or anywhere else, you'll always be able to call up Dockat by swiping up from the bottom edge of the screen, which is exactly the same as launching Google Now.
You can make your own Dockat by adding the most frequently used and favorite apps just like Dock.app in OS X.
And there are more:
1. Music Controller
Display the information of the now-playing music with three function keys, Fast Forward / Rewind and Pause / Play.
2. Quick Settings
Easy access to the Setting Menu and a slider to adjust the brightness setting.
3. Full-screen gestures
Swipe down to expand the notification panel. Especially designed for large screen phones.
