Android地理围栏退出触发器

我一直在尝试实现geofence来启动我的应用程序中的某个服务,虽然enter触发器起作用,但我似乎无法让exit触发器也正常工作。

private val geofencePendingIntent: PendingIntent by lazy {
    val intent = Intent(this, GeofenceBroadcastReceiver::class.java)
    intent.action = GEOFENCE
    PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)
}
private fun addGeoFence() {
    val geoFenceRequest = getGeoFencingRequest()
    checkOrAskLocationPermission {
        geofencingClient.addGeofences(geoFenceRequest, geofencePendingIntent)
            .addOnSuccessListener {
                Log.d(TAG, "GeoFence Added")
            }.addOnFailureListener {
                Log.d(TAG, "GeoFence Failed to Add")
            }
    }
}

private fun getGeoFencingRequest(): GeofencingRequest {
    val geoFence = Geofence.Builder()
        .setRequestId(GEO_FENCING_REQUEST_CODE)
        .setExpirationDuration(Geofence.NEVER_EXPIRE)
        .setCircularRegion(
            lat,
            lng,
            radius
        )
        .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER or Geofence.GEOFENCE_TRANSITION_EXIT)
        .build()

    val geoFenceList: MutableList<Geofence> = mutableListOf(geoFence)

    return GeofencingRequest.Builder().apply {
        setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER or GeofencingRequest.INITIAL_TRIGGER_EXIT)
        addGeofences(geoFenceList)
    }.build()
}

这是接受器,我得在触发后做点什么

class GeofenceBroadcastReceiver : BroadcastReceiver() {

override fun onReceive(context: Context?, intent: Intent?) {
    val geofencingEvent = GeofencingEvent.fromIntent(intent)
    val geofenceTransition = geofencingEvent.geofenceTransition

    context?.let {
        if (intent?.action == Constants.GEOFENCE)
            if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER) {
                //Start 
            } else if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {
                //Stop 
            }
    }
}

}

对于额外的上下文,我在firebase上设置了lat long,当我第一次用radius 100设置它们时,我看到了enter触发器,但是即使我将radius设置为1,它也永远不会触发退出,或者我真的必须带着设备本身移动到很远的地方?
