Please note, this widget requires ROOT access, explicitly for Android KitKat 4.4+, since media re-scan now requires system level access as of KitKat.
Did you just adb push a bunch of new media files (images / music) to your SDCARD but not seeing them in your gallery app, etc? Don't want to thumb through your app drawer to launch an application to initiate a re-scan? Don't want a force close when / if you do launch?
Give 'Media Rescan Widget' a try! It's the quickest and easiest way to initiate a re-scan of your media files.
Simply add the 2x2 widget to your home screen, grant root privileges after your initial launch, and enjoy an up to date gallery!
Note, this is a widget only, there is NO application icon that will appear in your app drawer.
To add as a widget to your home-screen, look for 'Media Rescan' in your 'choose widget' list.
If you do not have root, the widget, when clicked, should exit gracefully with a message stating 'root is required' and as a result, your media / gallery will not be updated. No need to download / install if you do NOT have root, as the widget will not provide any value.
