Answer 1

OK.. sounds like you have SDK3.x and above only functionality in your bluetoothChat app. For a start, the action bar is an android 3+ feature. in this case you will have a problem going back to target Android v2.2

my copy of the example app came from the 2.1 examples, and it works fine with SDK 2.1 (played with this the most) and 2.2 (just changed to this) and I can’t find anywhere it used listenUsingInsecureRfcommWithServiceRecord() in any of my java files.

Try using your SDK manager to grab the SDK 2.2 samples, and re-import from there and see if you have the same problems.
