Tracking bug for exploring the move to BlueDroid Stack. Currently we are based on BlueZ in V1.0.1 and V1.1. Proposal here is to support Bluedroid stack for a few market driven reasons. (e.g. Android supporting Bluedroid starting JB, makes it easy for OEM partners to have common stacks etc) [There is no decision on if or when we should drop support for BlueZ stack. Current thinking is that we will continue supporting that indefinitely for compatibility with our Desktop/Linux versions.]
