如何使用 GoogleApi 接口替换已弃用的 GoogleApiClient？

问题描述

我正在尝试学习我正在开发的应用的地理围栏教程。下面是 GeolocationService 的部分代码，但它使用的是已弃用的 Googleapiclient。我一直在阅读 this 文档，其中建议更改为 GoogleApi 界面。我一直无法弄清楚事情。我的问题似乎与“buildGoogleapiclient”方法有关。我似乎无法理解将 GoogleApi 接口用于 LocationServices 的正确语法。我们将不胜感激任何有关如何实现此目标（或实现此目标的更好方法）的帮助、建议或示例。

public class GeolocationService extends Service implements ConnectionCallbacks,OnConnectionFailedListener,LocationListener,ResultCallback<Status> {
    public static final long UPDATE_INTERVAL_IN_MILLISECONDS = 10000;
    public static final long FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS = UPDATE_INTERVAL_IN_MILLISECONDS / 5;
    protected Googleapiclient mGoogleapiclient;
    protected LocationRequest mLocationRequest;

    private PendingIntent mPendingIntent;

    @Override
    public void onStart(Intent intent,int startId) {
        buildGoogleapiclient();

        mGoogleapiclient.connect();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();

        if (mGoogleapiclient.isConnected()) {
            mGoogleapiclient.disconnect();
        }

    }

    protected void registerGeofences() {
        if (MainActivity.geofencesAlreadyRegistered) {
            return;
        }

        Log.d("Geofence","Registering Geofences");

        HashMap<String,SimpleGeofence> geofences = SimpleGeofenceStore
                .getInstance().getSimpleGeofences();

        GeofencingRequest.Builder geofencingRequestBuilder = new GeofencingRequest.Builder();
        for (Map.Entry<String,SimpleGeofence> item : geofences.entrySet()) {
            SimpleGeofence sg = item.getValue();

            geofencingRequestBuilder.addGeofence(sg.toGeofence());
        }

        GeofencingRequest geofencingRequest = geofencingRequestBuilder.build();

        mPendingIntent = requestPendingIntent();

        **LocationServices.GeofencingApi.addGeofences(mGoogleapiclient,geofencingRequest,mPendingIntent).setResultCallback(this);**

        MainActivity.geofencesAlreadyRegistered = true;
    }

    private PendingIntent requestPendingIntent() {

        if (null != mPendingIntent) {

            return mPendingIntent;
        } else {

            Intent intent = new Intent(this,GeofenceReceiver.class);
            return PendingIntent.getService(this,intent,PendingIntent.FLAG_UPDATE_CURRENT);

        }
    }

    public void broadcastLocationFound(Location location) {
        Intent intent = new Intent("geolocation.service");
        intent.putExtra("latitude",location.getLatitude());
        intent.putExtra("longitude",location.getLongitude());
        intent.putExtra("done",1);

        sendbroadcast(intent);
    }

    **protected void startLocationUpdates() {
        LocationServices.FusedLocationApi.requestLocationUpdates(
                mGoogleapiclient,mLocationRequest,this);
    }**

    protected void stopLocationUpdates() {
        LocationServices.FusedLocationApi.removeLocationUpdates(
                mGoogleapiclient,this);
    }

    @Override
    public void onConnected(Bundle connectionHint) {
        Log.i("Geofence","Connected to Googleapiclient");
        **startLocationUpdates();**
    }

    @Override
    public void onLocationChanged(Location location) {
        Log.d("Geofence","new location : " + location.getLatitude() + ","
                        + location.getLongitude() + ". "
                        + location.getAccuracy());
        broadcastLocationFound(location);

        if (!MainActivity.geofencesAlreadyRegistered) {
            registerGeofences();
        }
    }

    @Override
    public void onConnectionSuspended(int cause) {
        Log.i("Geofence","Connection suspended");
        mGoogleapiclient.connect();
    }

    @Override
    public void onConnectionFailed(ConnectionResult result) {
        Log.i("Geofence","Connection Failed: ConnectionResult.getErrorCode() = "
                        + result.getErrorCode());
    }

    *protected synchronized void buildGoogleapiclient() {

        mGoogleapiclient = new Googleapiclient.Builder(this)
