Didenterregion не вызывается в фоновом режиме при использовании regionbootstrap в altbeacon

Question

Я занимаюсь разработкой приложения для сканирования маяков, используя библиотеку altbeacon в Android.На переднем плане это обнаружение правильно.Но в фоновом режиме, используя regiobootstrap, он не обнаруживает.didenterrgion и didexitregion не звонит.Только didDetermineStateForRegion звонит с состоянием 0. Мне нужно запустить действие, когда маяк обнаружен в фоновом режиме.Пожалуйста, помогите мне.

public class MyApplication extends Application implements BootstrapNotifier {
private static final String TAG = ".MyApplicationName";
private RegionBootstrap regionBootstrap;
private Identifier identifier;

@Override
public void onCreate() {

    Log.d(TAG, "App started up");
    BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);

    beaconManager.getBeaconParsers().add(new BeaconParser()
            .setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));

    identifier = Identifier.parse("E2C56DB5-DFFB-48D2-B060-D0F5A71096E0"); //beacon 1
    beaconManager.setBackgroundBetweenScanPeriod(5001);
    beaconManager.setBackgroundScanPeriod(5001);

Notification.Builder builder = new Notification.Builder(this);
    builder.setSmallIcon(R.mipmap.ic_launcher);
    builder.setContentTitle("Scanning for Beacons");
    Intent intent = new Intent(this, SplashActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(
            this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT
    );
    builder.setContentIntent(pendingIntent);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel channel = new NotificationChannel("My Notification Channel ID",
                "My Notification Name", NotificationManager.IMPORTANCE_DEFAULT);
        channel.setDescription("My Notification Channel Description");
        NotificationManager notificationManager = (NotificationManager) getSystemService(
                Context.NOTIFICATION_SERVICE);
        notificationManager.createNotificationChannel(channel);
        builder.setChannelId(channel.getId());
    }
    beaconManager.enableForegroundServiceScanning(builder.build(), 456);
    beaconManager.setEnableScheduledScanJobs(false);



    Region region = new Region("com.example.myapp.boostrapRegion", identifier, null, null);

    regionBootstrap = new RegionBootstrap(this, region);
    super.onCreate();
}



@Override
public void didEnterRegion(Region region) {
    /*regionBootstrap.disable();*/
    Log.i(TAG, "didenterregion");
    Toast.makeText(this, "entered", Toast.LENGTH_SHORT).show();
    Intent intent = new Intent(this, SplashActivity.class);
    // IMPORTANT: in the AndroidManifest.xml definition of this activity, you must set android:launchMode="singleInstance" or you will get two instances
    // created when a user launches the activity manually and it gets launched from here.
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    this.startActivity(intent);
}

@Override
public void didExitRegion(Region region) {
    Log.i(TAG, "didexitregion!");
    Toast.makeText(this, "exit", Toast.LENGTH_SHORT).show();
}

@Override
public void didDetermineStateForRegion(int i, Region region) {
    Log.i(TAG, " diddeterminateregion!"  +i);
    Toast.makeText(this, ""+i, Toast.LENGTH_SHORT).show();

}
}

Вот мой фрагмент сканирования переднего плана:

 public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    Log.d("scannerfragment","oncraeteview");

    view= inflater.inflate(R.layout.fragment_scanning, container, false);

    beaconManager = BeaconManager.getInstanceForApplication(getActivity());

    bt_scan_again=view.findViewById(R.id.bt_scan_again);

    bt_scan_again.setOnClickListener(this);



    beaconManager.getBeaconParsers().add(new BeaconParser()
            .setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));


    beaconManager.setForegroundScanPeriod(5001);
    beaconManager.setForegroundBetweenScanPeriod(5001);

     identifier = Identifier.parse("E2C56DB5-DFFB-48D2-B060-D0F5A71096E0"); //beacon 1

    region = new Region("myMonitoringUniqueId", identifier, null, null);



    return view;

}
@Override
public void onClick(View v) {

    switch (v.getId()){

        case R.id.bt_scan_again:

            beaconManager.bind(this);
    }

                Collections.sort((List<Beacon>) beacons, new Comparator<Beacon>()
                {
                    @Override
