Hi,

I'm trying to write an application using Bluetooth on Android 1.6. Since it's not officially supported, I found the backport of android.bluetooth API ( http://code.google.com/p/backport-android-bluetooth ). But when I deploy the sample chat application (modified for backport) LogCat gives me the error below:

My question is, how I can use backport-android-bluetooth on 1.6 and is there any working samples?

Thanks!
