GoogleApiClientはサービス内で接続されたメソッドを呼び出さない

Question

サービスから位置を更新しようとしていますが、接続するためにgoogleApiClientを呼び出すと、onConnected、onConnectionSuspended、onConnectionFailedなどのメソッドが呼び出されません。

はここで完全なコードです：

public abstract class BASE_LOCAT_SERVICE extends Service implements 
     GoogleApiClient.ConnectionCallbacks, 
     GoogleApiClient.OnConnectionFailedListener, LocationListener { 

    public String TAG="LOC_SERVICE"; 

    public GoogleApiClient googleApiClient; 
    private Location lastLocation; 
    private static int UPDATE_INTERVAL = 5000; 
    private static int DISPLACEMENT = 10; 
    private LocationRequest locationRequest; 


    @Override 
    public void onCreate() { 
     super.onCreate(); 
     Log.i(TAG+"_LOC","On create Command"); 
     buildGoogleApiClient(); 
    } 


    protected synchronized void buildGoogleApiClient() { 
     googleApiClient = new GoogleApiClient.Builder(this) 
      .addConnectionCallbacks(this) 
      .addOnConnectionFailedListener(this) 
      .addApi(LocationServices.API).build(); 
     Log.i(TAG+"_LOC","googleApiClient Connecting"); 
    } 

    protected void createLocationRequest() { 
     locationRequest = new LocationRequest(); 
     locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); 
     locationRequest.setInterval(UPDATE_INTERVAL); 
     locationRequest.setSmallestDisplacement(DISPLACEMENT); 
     Log.i(TAG+"_LOC","createLocationRequest"); 
    } 


    private void initialiseWithLastLocation() { 
     try{ 
      lastLocation = LocationServices.FusedLocationApi.getLastLocation(
        googleApiClient); 
      Log.i(TAG+"_LOC","initialiseWithLastLocation Initialised"); 
     }catch(SecurityException ex){ 
      Log.e(TAG+"_LOC", "Unable to get last known location", ex); 
     } 
    } 

    protected void startLocationUpdates() { 

     try { 
      LocationServices.FusedLocationApi.requestLocationUpdates(
        googleApiClient, locationRequest, this); 
      Log.i(TAG+"_LOC","startLocationUpdates Initialised"); 
     } catch (SecurityException ex) { 
      Log.e(TAG+"_LOC", "Unable to get Last Known location", ex); 
     } 
    } 

    @Override 
    public void onConnected(@Nullable Bundle bundle) { 
     createLocationRequest(); 
     initialiseWithLastLocation(); 
     startLocationUpdates(); 
     Log.i(TAG+"_LOC","googleApiClient Connected"); 
    } 

    @Override 
    public void onConnectionSuspended(int i) { 
     Log.i(TAG+"_LOC","googleApiClient onConnectionSuspended"); 
    } 

    @Override 
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) { 
     Log.i(TAG+"_LOC","googleApiClient onConnectionFailed"); 
    } 

    @Override 
    public void onLocationChanged(Location location) { 
     lastLocation = location; 
     Log.i(TAG+"_LOC"," onLocationChanged"); 
    } 

    public String getLastLocation() 
    { 
     if(lastLocation!=null) 
     { 
      String ret="Location : \n"; 

      ret = ret+"Latitude : "+lastLocation.getLatitude()+"\n"; 
      ret = ret+"Longitude : "+lastLocation.getLongitude()+"\n"; 
      ret = ret+"Altitude : "+lastLocation.getAltitude()+"\n"; 
      ret = ret+"Accuracy : "+lastLocation.getAccuracy()+"\n"; 
      ret = ret+"Provider : "+lastLocation.getProvider()+"\n"; 
      ret = ret+"Speed : "+lastLocation.getSpeed()+"\n"; 
      ret = ret+"MAP Link : https://www.google.com/maps/?q="+lastLocation.getLatitude()+","+lastLocation.getLongitude()+"\n"; 

      return ret; 
     } 
     else 
      return "Location Not Available"; 
    } 
} 

とlogcatが表示さだけこの：

LOC_SERVICE_LOC: On create Command 
LOC_SERVICE_LOC: googleApiClient Connecting

あなたはmGoogleApiClient.connect（）

@Override 
public int onStartCommand(Intent intent, int flags, int startId) { 
    if (mGoogleApiClient != null) { 
     mGoogleApiClient.connect(); 
    }else{ 
     Toast.makeText(getApplicationContext(),"mGoogleApiClient is null",Toast.LENGTH_LONG).show(); 
    } 
    return START_STICKY; 
}
