我正在做的安卓服务有问题。服务将每5分钟获取一次用户的位置。一切似乎都很顺利，除了当我关闭应用程序，服务不会做什么。在代码中，我想你会每60秒检查一次，但这会改为5分钟。

执行服务的代码：

AlarmManager am=(AlarmManager)getApplicationContext().getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getApplicationContext(), LocationService.class);                            intent.setAction(Constants.ACTION_START_LOCATION_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(getApplicationContext(), Constants.LOCATION_SERVICE_ID, intent, PendingIntent.FLAG_UPDATE_CURRENT);
am.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime(), 60000, pendingIntent);

服务：

public class LocationService extends Service {
private LocationCallback locationCallback = new LocationCallback() {
    @Override
    public void onLocationResult(LocationResult locationResult) {
        super.onLocationResult(locationResult);

            double latitude = locationResult.getLastLocation().getLatitude();
            double longitude = locationResult.getLastLocation().getLongitude();
