[android-developers] Re: How to force MediaStore to rescan the SD card
I'm writing a Video Player and is supposed to cowork with Youtube
Downloader, which does not imeplemet MediaScanner when downloading a
file.
Is the only way for me is to scan whole SD card and update all found
files?

Under what circumstances would files be deleted without mounting and
re-mounting the SD card? That sounds like a poorly behaved app.

Now what ifmediafiles are deleted?
What if I do not know which ones have been deleted?
Is there a way to have it rescan the entire SD card in the
way it must do if the card has been removed and reinserted?

Toscana file, you just create a new MediaScannerNotifier:
new MediaScannerNotifier(path, mimeType);

I'm not sure about the process of removing a file from the database. I
suggest looking at the Music Player source - it has an option to
delete files from the SD card.
Under what circumstances would files be deleted without mounting and
re-mounting the SD card? That sounds like a poorly behaved app.
