问题
I want to set a FileObserver in the bluetooth folder. My problem is that this folder is different depending on the device, for example in Galaxy S is "mnt/sdcard/bluetooth" and in the Desire is "mnt/sdcard/downloads/bluetooth". Is there any way to get programatically that folder to be able to do the application device independient?
Thanks.
Santi.

Check this method: getExternalFilesDir(String type). And use DIRECTORY_DOWNLOADS as type.
If you add "bluetooth" to the end you'll get the bluetooth download directory.
