AltBeacon: So finden Sie eine Liste von Beacons mit RegionBootstrap und RangeNotifier

Question

Ich möchte, dass meine Anwendung nach Beacons im Hintergrund sucht. Wenn sie mit meinen Beacons übereinstimmen, wird ein Dialog geöffnet. So habe ich diese Klasse

In oben Klasse BootstrapNotifier gut funktioniert. Aber RangeNotifier nicht. BootstrapNotifier sagt, dass es eine Bake in der Nähe gibt, aber es gibt mir keine Liste von Beacons, also habe ich gezwungen, RangeNotifier zu verwenden, aber es funktioniert nicht. Können Sie mir bitte helfen, eine Lösung dafür zu finden? Dank sehr viel

Answer 1

Achten Sie darauf, den Bereich Anmelder wie folgt festgelegt:

(Wenn Sie Library, Version haben 2.9+)

beaconManager.addRangeNotifier(this);

(Wenn Sie Library, Version pre-2.9)

beaconManager.setRangeNotifier(this);
