Based on the results of my query in this thread, I've decided that I need to maintain my own database of metadata for the media that I'll be accessing. It seems like MediaStore is a very good start for this, as it will give me a good deal of information and is regularly updated by the MediaScanner. In an ideal world, I would add a few co...

Firstly, I realize this doesn't follow any particular convention. I'm just wondering if it is possible. I'd like to give my users the ability to perform an action on many items in a ListView. My ListView items already contain a checkbox for something different; and adding another checkbox is not an option (it would look ugly?). I was...
