Geofencing Example Google API

您可以在添加地理栅栏对象时设置expirationDurationTime.

如何在AndroID中设置启动Geofence Monitoring的时间？
例：

我希望明天14:30到15:30在“abc”位置进行地理围栏监测,并进行“xyz”地理围栏循环
我没有找到谷歌地理围栏API提供的任何功能,我可以设置开始监控地理围栏对象的时间.

请帮我.我现在非常绝望:(

从@Pavneet_Singh的帖子中读到WorkManager之后
我仍然混淆如何在这里组合WorkManager,因为我已经使用IntentService扩展了我的类,以便从Location.Service获得意图.

公共类GeofenceTransitionsIntentService扩展IntentService {

private final String TAG = "GeofenceTransIntServ";/** * Creates an IntentService.  Invoked by your subclass's constructor. * * @param name Used to name the worker thread,important only for deBUGging. */public GeofenceTransitionsIntentService(String name) {    super(name);}/** * This method is invoked on the worker thread with a request to process. * Only one Intent is processed at a time,but the processing happens on a * worker thread that runs independently from other application logic. * So,if this code takes a long time,it will hold up other requests to * the same IntentService,but it will not hold up anything else. * When all requests have been handled,the IntentService stops itself,* so you should not call {@link #stopSelf}. * * @param intent The value passed to {@link *               Context#startService(Intent)}. *               This may be null if the service is being restarted after *               its process has gone away; see *               {@link Service#onStartCommand} *               for details. */@OverrIDeprotected voID onHandleIntent(@Nullable Intent intent) {    GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);    if (geofencingEvent.hasError()) {        String errorMessage = GeofenceErrorMessages.getErrorString(this,geofencingEvent.getErrorCode());        Log.e(TAG,errorMessage);        return;    }    // Get the Transition type.    int geofenceTransition = geofencingEvent.getGeofenceTransition();    // Test that the reported Transition was of interest.    if (geofenceTransition == Geofence.GEOFENCE_Transition_ENTER ||            geofenceTransition == Geofence.GEOFENCE_Transition_EXIT) {        // Get the geofences that were triggered. A single event can trigger        // multiple geofences.        List<Geofence> triggeringGeofences = geofencingEvent.getTriggeringGeofences();        // Get the Transition details as a String.        String geofenceTransitionDetails = getGeofenceTransitionDetails(                geofenceTransition,triggeringGeofences        );        // Send notification and log the Transition details.        sendNotification(geofenceTransitionDetails);        Log.i(TAG,geofenceTransitionDetails);    } else {    // Error    }}private voID sendNotification(String geofenceTransitionDetails) {    // send notification}/** * Gets Transition details and returns them as a formatted string. * * @param geofenceTransition    The ID of the geofence Transition. * @param triggeringGeofences   The geofence(s) triggered. * @return                      The Transition details formatted as String. */private String getGeofenceTransitionDetails(        int geofenceTransition,List<Geofence> triggeringGeofences) {    String geofenceTransitionString = getTransitionString(geofenceTransition);    // Get the IDs of each geofence that was triggered.    ArrayList<String> triggeringGeofencesIDsList = new ArrayList<>();    for (Geofence geofence : triggeringGeofences) {        triggeringGeofencesIDsList.add(geofence.getRequestID());    }    String triggeringGeofencesIDsstring = TextUtils.join(",",triggeringGeofencesIDsList);    return geofenceTransitionString + ": " + triggeringGeofencesIDsstring;}private String getTransitionString(int geofenceTransition) {    // get the TransitionType as String    return null;}

}

我的想法 ：
将GeofenceTransitionsIntentService中的notificationMessage传递给另一个从Worker扩展的类,并使用setinitialdelay方法推迟通知？

我发现有人用JobIntentService扩展了GeofenceTransitionsIntentService类,但我认为我不能用JobIntentService扩展我的类,因为JobIntentService不提供延迟功能.

我怎么能让它现在起作用,我是否正确思考？

谢谢

@H_404_4@解决方法 您实际上是在询问在某个特定时间触发的警报机制.
有很多选项可以做到这一点

最优方案：

> WorkManager
> JobScheduler

其他(由于Naught,Oreo的背景限制)

>报警

有了上述功能,您可以在特定时间开始执行任务
