在Google Play服务10.0.1中，对于以下代码，在构建它时，我收到错误：
“GooglePlayServicesClient”无法解析符号
知道如何解决这个问题吗？

正如answer中提到的那样，我猜GooglePlayServiceClient已经过时了，所以请将其移除并使用GoogleApiClient代替。同时引入LocationServices.API和FusedLocationProviderApi
使用GoogleApiClient：
要使用GoogleApiClient，首先要改变的是接口，活动或服务正在实施
//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
GooglePlayServiceClient中的，mLocationClient只是一个普通的类构造函数。
在GoogleApiClient中使用的构建器如下：
//old code of GooglePlayServiceClient :
LocationClient mLocationClient;
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
mLocationClient = new LocationClient(this, this, this);
mLocationClient.connect();
}
将其替换为GoogleApiClient的新构建器代码：
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();
}
示例： 申请地点： 旧代码只是一个简单的调用，如
mLocationClient.requestLocationUpdates(mLocationRequest, locationListener);
在GoogleApiClient中，我们使用FusedLocatonApi，如：
LocationServices.FusedLocationApi.requestLocationUpdates(mLocationClient, mLocationRequest, locationListener);
This post向您展示了大多数方法的实现，例如：onConnected onConnectionFailed onConnectionSuspended等。
