We can remember it as a non persist global value when user click no. This value won't be saved when power down. We will restore the permission choice when we are disconnected with the remote device. So the "no" choice selected by user will only take effect until we are disconnected with the remote device. bug:11176511 Change-Id: Ic0c0829587cf7a812b5fa96fbd381921f67c186f
