Also note that we support only Android 4.4 and newer.

Android 4.2.2 might is missing required functionality in bionic and due to 
backward incompatible changes in BT HAL API our library will not compile 
against Android 4.2.

So if you really want to use that on Android 4.2 you must be prepared for some 
patching (both BLueZ and Bionic, and possibly other Android components).
