hey, thanks for your options. At the end, as a temporal solution I'm just running the media scanner when I exit my application. It is not the best option, but it's the only one that works in every device I can test in. I tried the option you said using ContentResolver, but it didn't work on the Galaxy S. If I can fix it, I'll post the solution.
Thanks!!
