It's not part of the official Android API. So it is very dangerous to
use, since it can (and probably will) break in a future OTA. It might
not work at all on some Android devices, since Android devices are
only required to implement the official API.

There is currently no way to determine if a Bluetooth device is
connected to the built-in Bluetooth headset service through the
official API.

If you can explain what you are trying to do, I might be able to
suggest a better alternative?
