Android has the MediaScanner that looks at the media on the device (internal and external storage) and builds a database of the tags for MP3 (and other files). This runs one start-up and can be triggered by sdcard mount/unmount. There is an open API to the MediaScanner that you can use to tell it to re-scan a single file. See scanFile in the MedisScannerConnection class. http://developer.android.com/reference/android/media/MediaScannerConnection.html#scanFile(android.content.Context, java.lang.String[], java.lang.String[], android.media.MediaScannerConnection.OnScanCompletedListener) -- Jeremy Wadsack -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
