gps - Android - Locations got from LocationClient doesn't support speed -

I am using the new Google LocationClient to recover the geographic location. And I need to get the speed for each point (space).
What I am doing now:

  if (mLocationClient == faucet) {mLocationClient = new location client (this, mLocation callback, mLocation callback); MLocationCallback.setLocationClient (mLocationClient); If (MLocationClient.isConnected ()) || mLocationClient.isConnecting ())) {mLocationClient.connect (); }}   
 Where mLocation is an example of callback  
  Public class space calculator applies the connection callback, on connectionfield listener, location listener {}  Public zero transfer (location location) in the  
 function,  
  @Orride {if (location == null) {Log.e (TAG, "onLocationChanged: location = = Null "); Return; } "+ Location.getAltitude () +" ("+ location.hasAltitude () +" ("location @" + location.getlighttime (+) + "," + location.getLongitude () + ", height: ")" + "Velocity:" + location.getSpeed ​​() + "m / s (" + location.has speed +++ ");}}   
 However, every time the  location.hasSpeed ​​()  returns  false . It seems that only the GPS provider provides the speed I'm sure my GPS is on but its Can not be used any way to apply the location client to use GPSClient Is there a way to use the GPS provider to be the location client?   
 
  
 No, because it can point to the  LocationClient  to multiple sources (GPS, WiFi, cell tower, sensor, etc.).  
 If needed, use  LocationManager  and work with  GPS_PROVIDER , or  criteria  is the speed (like, Galileo, someday, maybe ).
