RemoveLocationUpdates () / requestLocationUpdates () or disconnect () / requestLocationUpdates ()

let's say I have an instance GoogleApiClient

and 2 LocationListener

s:

GoogleApiClient gac = new GoogleApiClient.Builder(this)
  .addApi( LocationServices.API )
  .addConnectionCallbacks( this )
  .addOnConnectionFailedListener( this )
  .build();

LocationListener listenerA, listenerB;

LocationRequest requestA, requestB;

initTheAboveInstances();

LocationServices.FusedLocationApi.requestLocationUpdates( gac, requestA, listenerA );

      

        
        
        
      

    

At some point, I want to replace listenerA

with listenerB

. What's the best (recommended) way to do this?

By

LocationServices.FusedLocationApi.removeLocationUpdates( gac, listenerA );
LocationServices.FusedLocationApi.requestLocationUpdates( gac, requestB, listenerB );

      

        
        
        
      

    

or:

gac.disconnect();
gac.connect();

      

        
        
        
      

    

and request updates in onConnected()

@Override
public void onConnected( Bundle state ) {
  LocationServices.FusedLocationApi.requestLocationUpdates( gac, requestB, listenerB );
}

      

        
        
        
      

    

?

my problem is that it listenerB.onLocationChanged()

doesn't get the call in some cases ...

TIA
