无法取得当前纬度和经度的android

我是新的android和我想获取我当前位置的经度和纬度，为此我使用'com.google.android.gms：play-services： 8.4.0'，我得到这个错误
java.lang.IllegalArgumentException：GoogleApiClient参数是必需的。和我提到了原先的stckoverflow的答案，但它因此未帮助me.Please帮助我，在此先感谢无法取得当前纬度和经度的android

，这里是Mapsactivity.java

public class MapsActivity extends FragmentActivity{ 

    private GoogleMap mMap; 
AppLocationService appLocationService; 
GoogleApiClient mGoogleApiClient; 
private Location mLastLocation; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_maps); 
    setUpMapIfNeeded(); 
} 

    private void setUpMapIfNeeded() { 
    if (mMap == null) { 

     mMap = ((SupportMapFragment) 
      getSupportFragmentManager().findFragmentById(R.id.map)) 
       .getMap(); 

     if (mMap != null) { 

      displayLocation(); 
     } 
    } 
} 
private void displayLocation() { 

    mLastLocation = LocationServices.FusedLocationApi 
      .getLastLocation(mGoogleApiClient); 

    if (mLastLocation != null) { 
     double latitude = mLastLocation.getLatitude(); 
     double longitude = mLastLocation.getLongitude(); 

     Log.d("result", latitude + ", " + longitude); 

    } else { 

     Log.d("result2","(Couldn't get the location. Make sure location is 
    enabled on the device)"); 
    } 
} 
}

的代码这里是我的清单文件的代码

不要张贴整个错误日志的样本。 –

您可能因为'mGoogleApiClient'未初始化而意外收到错误 - 这意味着您将''.getLastLocation（mGoogleApiClient）''调用了'GoogleApiClient'实例作为参数。 – ishmaelMakitla

@ishmaelMakitla初始化后，我无法看到我的logcat中的经度或纬度 – user3923278

你尚未初始化mGoogleApiClient变量。请先初始化它。

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

mLastLocation = LocationServices.FusedLocationApi 
      .getLastLocation(mGoogleApiClient);

注：这只是初始化GoogleApiClient

添加上面的代码段后，它解决了这个错误，但在我的logcat中，我无法看到经度和纬度，我得到这些错误在我的控制台 – user3923278

** E/CardSyncManagerImpl：onConnectionFailed：ConnectionResult {statusCode = API_UNAVAILABLE，resolution = null，message = null} ** – user3923278

** I/Finsky：[1] com.google.android.finsky.cla（270）：result = false type = 4 ** – user3923278
