GeoFence警報不顯示

Question

使用下面的代碼添加地理圍欄後，Notification未顯示.even onResult回調正在迴應成功。

添加地理圍欄在GoogleApiClientApi onConnected()回調方法：

public void onConnected(Bundle bundle) { 
     LocationServices.GeofencingApi.addGeofences(
       googleApiClient, 
       getGeofencingRequest(), 
       getGeofencePendingIntent() 
     ).setResultCallback(this); 
    } 

請求地理柵欄：

private GeofencingRequest getGeofencingRequest() { 
     geoFenceList.add(new Geofence.Builder() 
       .setRequestId("myFence") 
       .setCircularRegion(68.441630, 77.310587, 2.0f) 
       .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER) 
       .setExpirationDuration(Geofence.NEVER_EXPIRE) 
       .build()); 
     GeofencingRequest.Builder builder = new GeofencingRequest.Builder(); 
     builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER); 
     builder.addGeofences(geoFenceList); 
     return builder.build(); 
    } 

onResult()回調;

public void onResult(Status status) { 
     if (status.isSuccess()){ 
      Toast.makeText(this,"Working",Toast.LENGTH_SHORT).show();//This Toast is showing/ 

     }else{ 
      Toast.makeText(this,"Not Working",Toast.LENGTH_SHORT).show(); 
     } 
    } 

意向服務觸發通知：

protected void onHandleIntent(Intent intent) { 
     GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent); 
     if (geofencingEvent.hasError()) { 

      return; 
     } 
     int geofenceTransition = geofencingEvent.getGeofenceTransition(); 
     if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER || 
       geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) { 

      NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); 
      Intent intent1 = new Intent(this, MainActivity.class); 
      intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP); 
      PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, intent1, PendingIntent.FLAG_UPDATE_CURRENT); 

      Notification notification = new NotificationCompat.Builder(this) 
        .setSmallIcon(R.mipmap.ic_launcher) 
        .setContentTitle("Your Geo") 
        .setContentText("This is My geo") 
        .setContentIntent(pendingNotificationIntent) 
        .setPriority(NotificationCompat.PRIORITY_HIGH) 
        .setAutoCancel(true) 
        .build(); 
      notificationManager.notify(0, notification); 
     } else { 
     }  
    } 

我覺得IntentService不inovked。我錯過了什麼？

這裏是我工作的代碼。我希望它的幫助ü..

public class AreWeThereIntentService extends IntentService { 
    private final String TAG = AreWeThereIntentService.class.getName(); 
    private SharedPreferences prefs; 
    private Gson gson; 
    MediaPlayer mp; 

    public AreWeThereIntentService() { 
     super("AreWeThereIntentService"); 
    } 

    TinyDB tinyDB; 
    ArrayList<Integer> myIntArr; 

    @Override 
    protected void onHandleIntent(Intent intent) { 
     prefs = getApplicationContext().getSharedPreferences(
       Constants.SharedPrefs.Geofences, Context.MODE_PRIVATE); 
     gson = new Gson(); 
     // 1. Get the event 
     GeofencingEvent event = GeofencingEvent.fromIntent(intent); 
     if (event != null) { 
      if (event.hasError()) { 
       onError(event.getErrorCode()); 
      } else { 
       // 2. Get the transition type 
       int transition = event.getGeofenceTransition(); 
       if (transition == Geofence.GEOFENCE_TRANSITION_ENTER || 
         transition == Geofence.GEOFENCE_TRANSITION_DWELL || 
         transition == Geofence.GEOFENCE_TRANSITION_EXIT) { 
        List<String> geofenceIds = new ArrayList<>(); 
        // 3. Accumulate a list of event geofences 
        for (Geofence geofence : event.getTriggeringGeofences()) { 
         geofenceIds.add(geofence.getRequestId()); 
        } 
        if (transition == Geofence.GEOFENCE_TRANSITION_ENTER || 
          transition == Geofence.GEOFENCE_TRANSITION_DWELL) { 
         // 4. Pass the geofence list to the notification method 
         onEnteredGeofences(geofenceIds); 
        } 
       } 
      } 
     } 
    } 

    private void onEnteredGeofences(List<String> geofenceIds) { 

     // 1. Outer loop over all geofenceIds 
     for (String geofenceId : geofenceIds) { 
      String geofenceName = ""; 
      // 2, Loop over all geofence keys in prefs and retrieve NamedGeofence from SharedPreferences 
      Map<String, ?> keys = prefs.getAll(); 
      for (Map.Entry<String, ?> entry : keys.entrySet()) { 
       String jsonString = prefs.getString(entry.getKey(), null); 
       NamedGeofence namedGeofence = gson.fromJson(jsonString, NamedGeofence.class); 
       if (namedGeofence.id.equals(geofenceId)) { 
        geofenceName = namedGeofence.name; 
        break; 
       } 
      } 
      myIntArr.add(Calendar.DAY_OF_WEEK); 
      int day = Calendar.DAY_OF_WEEK; 
      myIntArr = tinyDB.getListInt("myList"); 

      // 3. Set the notification text and send the notification 
      String contextText = 
        String.format(this.getResources().getString(R.string.Notification_Text), geofenceName); 
      // 1. Create a NotificationManager 
      NotificationManager notificationManager = 
        (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); 

      Intent intent = new Intent(this, MapsActivity.class); 
      intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP); 
      PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

      Uri alarmSound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE 
        + "://" + getPackageName() + "/raw/battlefield"); 

      int timeout = 20000; 
      long[] pattern = {0, 100, 200, 300}; 
      mp = new MediaPlayer(); 
      mp = MediaPlayer.create(getBaseContext(), R.raw.battlefield); 
      mp.setAudioStreamType(AudioManager.STREAM_MUSIC); 
      mp.setLooping(true); 
      mp.start(); 

      final Handler handler = new Handler(); 
      handler.postDelayed(new Runnable() { 
       @Override 
       public void run() { 
        if (mp.isPlaying()) { 
         mp.stop(); 
        } 
       } 
      }, timeout); 

      Notification notification = new NotificationCompat.Builder(this) 
        .setSmallIcon(R.mipmap.map_marker_icon) 
        .setContentTitle(this.getResources().getString(R.string.Notification_Title)) 
        .setContentText(contextText) 
        .setContentIntent(pendingNotificationIntent) 
        .setStyle(new NotificationCompat.BigTextStyle().bigText(contextText)) 
        .setPriority(NotificationCompat.PRIORITY_HIGH) 
        .setAutoCancel(true) 
        .setWhen(System.currentTimeMillis()) 
        .build(); 
      notificationManager.notify(0, notification); 

       /* AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
      Intent myIntent = new Intent(this, AlarmReciver.class); 
      PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT); 
      alarmManager.set(AlarmManager.RTC_WAKEUP, 1, pendingIntent); 
      alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (1000 *30), pendingIntent);*/ 


     } 
    } 

    private void onError(int i) { 
     Log.e(TAG, "Geofencing Error: " + i); 
    } 
} 

，並確保你在manifest文件中加入這一行：

<service android:name=".AreWeThereIntentService" />
