错误出在这两个进口和相应的类（1）进口com.google .android.gms.location.LocationClient; （2）import com.google.android.gms.common.GooglePlayServicesClient; ，我编译了“com.google.android.gms：play-services：10.0.1”，但仍无法解决上述导入问题 –

清理代码和问题以便于阅读/理解 – clearlight

在本answer提到我猜GooglePlayServiceClient，并已成为过时因此将其删除，并使用GoogleApiClient instead.Also LocationServices.API，并介绍FusedLocationProviderApi。

GoogleApiClient的用法：

要使用GoogleApiClient首先要改变的是接口，活动或服务在GooglePlayServiceClient实施

//old code of GooglePlayServiceClient : 
public class LocationMonitoringService extends Service implements GooglePlayServicesClient.ConnectionCallbacks 

//replace the above^code with this: new code for GoogleApiClient 
public class LocationMonitoringService extends Service implements GoogleApiClient.ConnectionCallbacks

，mLocationClient只是一个普通类的构造函数。在GoogleApiClient一个生成器使用，如：

//old code of GooglePlayServiceClient : 
LocationClient mLocationClient; 

    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 
    mLocationClient = new LocationClient(this, this, this); 
    mLocationClient.connect(); 
    }

替换它^与GoogleApiClient的新建设者代码：

GoogleApiClient mLocationClient; 

@Override 
public int onStartCommand(Intent intent, int flags, int startId) { 
    mLocationClient = new GoogleApiClient.Builder(this) 
      .addConnectionCallbacks(this) 
      .addOnConnectionFailedListener(this) 
      .addApi(LocationServices.API) 
      .build(); 

    mLocationClient.connect(); 
}

例子： 请求位置：旧代码就像一个简单的调用

mLocationClient.requestLocationUpdates(mLocationRequest, locationListener);

in GoogleApiClient我们使用FusedLocatonApi像：

LocationServices.FusedLocationApi.requestLocationUpdates(mLocationClient, mLocationRequest, locationListener);

This post显示你最像的方法实现：onConnectedonConnectionFailedonConnectionSuspended等

可以用于“LocationClient”吗？ –

我已更新答案，查看可能有用的链接。 – anotherGatsby

用什么来代替“LocationClient mLocationClient”？你能帮我么？ –
