Open up your Gallery app on your Android device. Go ahead; I dare you. Notice a bunch of clutter in there from things you don’t want showing up? If you’ve got a little bit of Android acumen, you are cognisant of the fact that placing a simple .nomedia file in the offending directory will exclude it from showing up in Android’s media handlers such as the Gallery and music player. Unfortunately, however, creating or copying a file manually is a bit of a drag.
In order to keep things simple, XDA forum member knox420 has created a wonderful little utility to place (and remove) these aforementioned .nomedia files quite easily.
Many apps create folders on the sd-card and drop their stuff there. Often, they place images as well. Now that Android checks the sd-card for new media from time to time, these folders will be added to the media database and displayed in the stock Gallery app.
Gallery Excluder lists all direct subfolders of ‘/sdcard’ respectively ‘/mnt/sdcard’ and displays them in a list. If an item/folder gets checked there is a ‘.nomedia’ placed in that folder. If the folder gets unchecked the ‘.nomedia’ is removed.
Since it can take a while to have the gallery update you can force a manual update via options menu.
Well, what are you waiting for? Make sure to make your way over to the application thread to get a piece of this yourself!_________
