backport-android-bluetooth is a backport of 2.0(or higher) bluetooth API.
you don't need this project.

Thanks for the update, though I think there was a misunderstanding on my part 
as to
the intended usage. 

To be clear, I was in fact trying to code for *both* Android 2.0 and earlier 
version,
not just Eclair.  What I misunderstood is that you need to still use reflection 
or an
interface to separate the two scenarios.  However, it would be nice not to have 
to
separate them, though that isn't a huge deal.  I do suggest that you update the
documentation at the very least to reflect that you can't simply use the 
backport for
both eclair *and* previous version of Android.

Anyways, thanks for coding this, it has worked well in my other tests.

see issue 6, perhaps a new issue should be opened? i.e support both 1.x and 2.x
