DeviceLocationProvider

Registers an observer in this instance of LocationProvider. One instance of LocationProvider can have more than one observer. It is expected that LocationProvider will not start until an observer is added. The observer registered will receive notifications on the same looper as the one where this method is invoked. If the looper is not available, this method can be called from any thread.
