我已使用待定意图启动广播接收器获取位置更新。
应用程序之前工作正常。
但从最近几个月开始就不管用了。
我检查并发现LocationReceiver.kt未获得任何更新

class LocationReceiver : BroadcastReceiver() {
private var locationRepository: LocationRepository? = null
private var lastLocation: Location? = null
override fun onReceive(context: Context, intent: Intent) {
val action = intent.action
if (Utility.currentApiVersion \>= Build.VERSION_CODES.O) NotificationHandler.getInstance(context).updateNotification(action)
Log.d("locationslog",""+action)
Utility.appToastShort(context, "onReceive: "+action)
if (ACTION_LOCATION_UPDATES == action) {
val result = LocationResult.extractResult(intent)
if (result != null) {
val locations = result.locations
if (locationRepository == null) locationRepository =
LocationRepository.getInstance(context.applicationContext, Executors.newSingleThreadExecutor())
if (locations.size \> 0) {
if (locations.size == 1 && lastLocation != null && lastLocation!!.latitude == locations\[0\].latitude && lastLocation!!.latitude == locations\[0\].longitude) {
//already saved location
} else {
for (i in locations.indices) {
if (i == locations.size - 1) lastLocation = locations\[i\]
val curntLoc = locations\[i\]
//LatLng curntLatLng = new LatLng(curntLoc.getLatitude(), curntLoc.getLongitude());
locationRepository!!.insertLocation(
LocationPoint(
curntLoc.latitude,
curntLoc.longitude
)
)
}
if (Utility.currentApiVersion \>= Build.VERSION_CODES.O) NotificationHandler.getInstance( context).updateNotification(
Utils.getLocationText(lastLocation)
)
}
}
}
}
}
