This is not overridden from BluetoothDeviceClient. Put it somewhere else.

[xiyuan, 2015/07/30 23:30:37]

What about this?

Missed that one, sorry about that.

Done

We should put all of the arguments after |device_path| into a struct. That will
clean up the DeviceEmulatorMessageHandler implementation as well.

Ideally we should use ScopedPtrMap now that it exists for this and
PropertiesMap.
