Android: Force Music Application to Refresh List of Playlists How can I force the built-in Music App in Android to refresh my list of playlists. Even after I delete one from my SD card, the playlist will still appear in my list of playlists.
Go to settings, applications, manage applications, [menu button], filter, all

Find the Media Storage app, and clear data.

This deletes everything! artists, albums, playlists. (data still on card)

Plug in, mount usb. Eject. Go back into music, and wait (a lot if you have more than a few tracks.)

Note: If the music app shows no changes, try force stopping the Media Storage app. The app showed no cache or data to clear, but force stopping it then opening the Music app worked for me.
