Android地理围栏退出触发器

我一直在尝试在我的应用程序中实现一个地理围栏来启动某项服务，虽然enter触发器工作，但我似乎无法让exit触发器也工作

我正在从firebase读取lat long radius，以便于访问和调试。这是我的代码：

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()
}

为什么退出转换从未触发

另外，我在firebase上有我的lat long，当我第一次用radius 100设置它们时，我看到enter触发器，但即使我将radius设置为1，它也不会触发出口，或者我必须用设备本身移动很远吗

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 
            }
    }
}

}
