为什么没有通过FusedLocationClient.requestLocationUpdates

Question

我只是想获得当前位置更新，当我摆脱当前的位置ATLEAST3米为了这个，我用

FusedLocationClient.requestLocationUpdates 

为了这个，我做LocationRequest提供当前位置和位置之间的差异像这样：

private LocationRequest requestLocation(){ 

LocationRequest mLocationRequest = new LocationRequest();                            
mLocationRequest.setSmallestDisplacement(3.81f);                                     
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);    
return mLocationRequest;               
} 

像这样实现的：连接后，扮演服务

@Override 
public void onConnected(Bundle bundle) {                 

mFusedLocationClient.requestLocationUpdates(requestLocation(), 
new LocationCallback() {    
    @Override                       
    public void onLocationResult(LocationResult locationResult) {          
     for (final Location location : locationResult.getLocations()) {        

      tvLat.setText(Double.toString(location.getLatitude()));         
      tvLng.setText(Double.toString(location.getLongitude()));         

      //changing position of marker and camera                      
      changeCameraPosition(CameraUpdateFactory.newLatLngZoom(         
      new LatLng(location.getLatitude(), location.getLongitude()),      
        16), new GoogleMap.CancelableCallback() {           

     @Override                    
     public void onFinish() {}               


     @Override                    
     public void onCancel() { }                

      });                      

     }                        
    }                         
    }, Looper.myLooper());                     

但是我越来越从这个ATLEAST650米远离我的当前位置经纬度，即使我没动丝毫，这是我的权限清单：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="permission.READ_GSERVICES" />

也许你可以检查此一：Android map Update location to server when there is difference of x meters between current location and last location，看到了当你移动时你的距离的差异，所以你会知道过度运动的来源发生在哪里。
