无法在 android 中获取当前纬度和经度

Question

我是 android 的新人，我正在尝试获取我当前位置的经纬度，为此我正在使用 'com.google.android.gms:play-services:8.4。 0' 我收到了这个错误
java.lang.IllegalArgumentException：需要 GoogleApiClient 参数。我参考了以前的 stckoverflow 答案，但它没有帮助 me.Please 帮助我，在此先感谢

这里是Mapsactivity.java

的代码

   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)");
     }
 }
}

这是我的清单文件的代码

您还没有初始化您的 mGoogleApiClient 变量。请先初始化。

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

 mLastLocation = LocationServices.FusedLocationApi
            .getLastLocation(mGoogleApiClient);

注意：这只是初始化 GoogleApiClient 的示例
