Android :: Need A Sequence Of Initialization Of Network Service Provider

I am trying to make the use of Network location provider to get the location updates, But it seems to be that Network location provider makes use of MASF client . From the debug statements we found that Network provider does seems to launch MASF client , Would some one explain me the basic sequence of initialization of Network service provider ? and if MASF client is not getting initialized do we need to do some settings. What do i need to check .Any information on this is Highly appreciated.
