Dropbox should respond to Android Intent.ACTION_SEND

Actually, looking around now, it does not seem to be common. I think I picked up 'file/*' from snippets provided for getting content, not sending content, but then combined it with other snippets designed for sending plain text or images. My specific requirement is that I wanted an all-purpose attachment/upload service, not one restricted to any known file type, and 'application/*' achieves this. The thing is, the above code worked immediately for a wide range of apps/services, so I almost stopped at that point and assumed DropBox was not willing to play ball.

I guess if you respond to */* that should be enough to satisfy other developers who try file/*, but in truth there might not be many. If there is no reason not to respond to */*, though, you might as well be flexible. DropBox doesn't seem to care what type of file it is, so why filter it?

Anyway, thanks for your help - you solved the issue for me.
