I have used SearchManager and it provides search key only when app is launched. Is there a way to put a text box on the home screen/wallpaper and invoke activity when user presses enter?

You can use widgets on the home screen, which you can have contain a textView and you can use an intent to launch an acticity you want on the press of enter - or any other event.
