Question

我正在尝试测试我的android geofencing应用。我已输入当前位置作为地理围栏纬度，位置并尝试测试应用程序是否有效。从技术上讲，当我运行应用程序时，我在地理围栏区域内。但是，当我启动应用程序时，我没有收到任何通知 - 当我在地理围栏区域内时，收到的转换类型为-1。我需要加入其他东西吗？以下是我目前的代码 -

//once connected to GoogleAPIClient

ArrayList<Geofence> geofences = new ArrayList<Geofence>();
geofences.add(new Geofence.Builder()
        .setRequestId("id")
        .setCircularRegion(
                lat, lon, GEOFENCERADIUS)
        .setTransitionTypes(
                Geofence.GEOFENCE_TRANSITION_ENTER | Geofence.GEOFENCE_TRANSITION_DWELL
                        | Geofence.GEOFENCE_TRANSITION_EXIT)
        .setLoiteringDelay(30000) // check every 30 seconds
        .setExpirationDuration(Geofence.NEVER_EXPIRE)
        .build());
        System.out.println("GEOFENCE ADDED");
    }

    GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
    builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
    builder.addGeofences(geofences);

    LocationRequest locationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY)
            .setFastestInterval(5000L).setInterval(10000L)
            .setSmallestDisplacement(75.0F);

    PendingIntent pendingIntent = PendingIntent.getService(this, 0,
            new Intent(this, GeofenceReceiver.class),
            PendingIntent.FLAG_UPDATE_CURRENT);

    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
            locationRequest, pendingIntent);

意向服务类如下：

public class GeofenceReceiver extends IntentService {

    public GeofenceReceiver()
    {
        super("GeoFenceReceiver");
    }

    @Override
    protected void onHandleIntent(Intent intent) {

        System.out.println("INTENT RECEIVED");

        GeofencingEvent geoEvent=GeofencingEvent.fromIntent(intent);

        if (geoEvent.hasError()) {
               //todo error process
            System.out.println("Error");
        }
        else {
               int transitionType = geoEvent.getGeofenceTransition();

               System.out.println(transitionType);

               if (transitionType == Geofence.GEOFENCE_TRANSITION_ENTER ||
                       transitionType == Geofence.GEOFENCE_TRANSITION_EXIT) {
                   List<Geofence> triggerList = geoEvent.getTriggeringGeofences();

                   for (Geofence geofence : triggerList) {
                       generateNotification(geofence.getRequestId(), "address you defined");
                   }
               }

               if(transitionType==-1)
               {
//                 System.out.println(intent.getAction());
               }
           }

当我运行应用程序时，我收到消息INTENT RECEIVED，但是，转换类型始终为-1。这是应用程序的工作问题吗？

PS：我确信这与GPS准确性无关，因为我已将地理围栏半径增加到2公里。所以我确信它有一些表示运行应用程序的过渡。

Android Geofencing：过渡类型
