Gimbal "BeaconSighting" 侦听器工作不稳定

Question

我正在尝试在 Android 中获取 Gimbal 信标距离变化运行时间。我能够连接到我的信标，同样反映在 android 应用程序中。

但我无法在应用程序中获得更改后的 RSSI。下面是我的代码。

private PlaceManager placeManager;
private PlaceEventListener placeEventListener;
private ArrayAdapter<String> listAdapter;
private ListView listView;
private BeaconManager bm;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    listAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1);
    listView = (ListView) findViewById(R.id.list);
    listView.setAdapter(listAdapter);

    listAdapter.add("Setting API Key");
    listAdapter.notifyDataSetChanged();
    Gimbal.setApiKey(this.getApplication(), "my key");

    bm = new BeaconManager();
    bm.addListener(new BeaconEventListener() {
        @Override
        public void onBeaconSighting(BeaconSighting beaconSighting) {

            super.onBeaconSighting(beaconSighting);

            Log.d("beacon1", beaconSighting.getBeacon().toString());
            Log.d("beacon2", String.format("", beaconSighting.getRSSI()));
        }
    });
    bm.startListening();


    placeEventListener = new PlaceEventListener() {

        @Override
        public void onVisitStart(Visit visit) {

            super.onVisitStart(visit);

            listAdapter.add(String.format("Start Visit for %s", visit.getPlace().getName()));
            listAdapter.notifyDataSetChanged();

            Log.d("1", String.valueOf(visit.getArrivalTimeInMillis()));
            Log.d("2", String.valueOf(visit.getDepartureTimeInMillis()));
            Log.d("3", String.valueOf(visit.getPlace()));
            Log.d("4", String.valueOf(visit.getDwellTimeInMillis()));
            /*BeaconSighting demo = new BeaconSighting();
            Beacon beac = demo.getBeacon();
            Log.d("", beac.getUuid());*/
        }

        @Override
        public void onVisitEnd(Visit visit) {

            super.onVisitEnd(visit);

            listAdapter.add(String.format("End Visit for %s", visit.getPlace().getName()));
            listAdapter.notifyDataSetChanged();

            Log.d("ending","ending");
        }
    };

    placeManager = PlaceManager.getInstance();
    placeManager.addListener(placeEventListener);
    placeManager.startMonitoring();

    CommunicationManager.getInstance().startReceivingCommunications();

下面是我的日志输出。

问题就出在这里

打印 "beacon1" 和 "beacon2" randomly/erratically。 我无法理解为什么“BeaconEventListener" 有这样的行为。大多数时候它根本没有打印出来。因此，我没有路障，因为我在移动时无法获得手机和信标之间的距离。

编辑

能够提取更多错误日志。在 logcat 输出中添加了最后两行。

感谢任何帮助。

Answer 1

Gimbal 团队几乎解决了这个问题，所以遇到这个问题的人将来也可以得到帮助。

在我的 OP 中，您可以看到下面是我的代码的原始部分。

bm = new BeaconManager();
bm.addListener(new BeaconEventListener() {
    @Override
    public void onBeaconSighting(BeaconSighting beaconSighting) {

        super.onBeaconSighting(beaconSighting);

        Log.d("beacon1", beaconSighting.getBeacon().toString());
        Log.d("beacon2", String.format("", beaconSighting.getRSSI()));
    }
});
bm.startListening();

现在我们还要在 PlaceEventListener() 中添加 onBeaconSighting()。所以代码的新部分将如下所示。

 placeEventListener = new PlaceEventListener() {

    @Override
    public void onVisitStart(Visit visit) {

        super.onVisitStart(visit);
        //do anything
    }

     @Override
     public void onVisitEnd(Visit visit) {

        super.onVisitEnd(visit);
        //do anything
     }

     public void onBeaconSighting(BeaconSighting sighting, List<Visit> visits) { 
     // This will be invoked when a beacon assigned to a place within a current visit is sighted. 
    }
  }

我们添加一个重复的或者更确切地说另一个监听器的原因由 Gimbal 团队回复如下。

Me : Can you inform me as why adding a duplicate listener made the code work ? As this listener is already handled in BeaconManger, it should have worked.

Gimbal Team : onBeaconSighting in PlaceManager will will be invoked when a beacon assigned to a place within a current visit is sighted. onBeaconSighting in BeaconManager will be invoked when a beacon is sighted.

我想我已经很清楚问题出在哪里以及如何解决了。希望对你也有帮助。

干杯。
