I'm using android 2.3.6. It automatically caches all the music that I add. This kind of annoys me because every time I delete a song the name of the song still appears in the music list. Therefore every time I make any changes I have to clear data from the Media App. I've been doing this for a long time and now I've had enough of it. Can someone tell me how to prevent auto caching of media files?
Very unlikely. That's the MediaScanner's responsibility. For faster access it scans all directories on given events (e.g. SDCard mounted, boot_completed) and stores the results in a database, where most players pick it up from.
So you can either use a tool like e.g. SDrescan to trigger the MediaPlayer's scan whenever you've manipulated files -- or find yourself a music player that doesn't use Android's media database but rather works e.g. folder based.
