我正在使用AltBeacon库构建应用程序以支持Onyx Beacons (Beacon One)和Gimbal Beacons (Series 21)
我的测试设备是带有Android 4.4.4 KitKat和Onyx Beacon的Nexus 7 2013。信标仅在我的设备旁边不到一米的位置，并且我没有移动它。检测到信标并进入didEnterRegion，大约一分钟后到达didExitRegion，然后重复该循环。
我们还使用其他（Onyx）信标在其他设备（三星手机）上对此进行了测试。仍然出现问题。请注意，这仅在Onyx Beacons (Beacon One)上发生。 Gimbal Beacons (Series 21)在范围内仅触发一次。
我是否使用正确的信标解析器字符串？我能正确实现吗？我真的没有主意，我想支持两个信标。

} catch (RemoteException e) { }
}
}
}
@Override

return null;
}
@Override

super.onDestroy();
}
private void sendNotification(Beacon beacon, InteractiveImage interactiveImage) {

.setAutoCancel(true)
.setContentTitle("Sample Beacon")
.setContentText("A beacon was detected")
.setSmallIcon(R.drawable.ic_launcher);

notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notifyIntent, 0);
notifBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Integer.parseInt(beacon.getId()), notifBuilder.build());

最佳答案
一些提示：
检查玛瑙信标之一的广告费率。为了获得最佳效果，信标应以10Hz的标准进行广告。一些制造商放慢了此广告投放速度，以节省电池寿命。如果您有一个以1Hz或更低频率进行广告的信标，则信标扫描仪可能会开始定期丢失它。 （由于蓝牙无线电噪声，未检测到100％的数据包。）
如果您发现广告速率为1 Hz或更低，请尽可能提高广告速率，并且问题将消失。
如果您无法提高信标的广告速率，则可以降低Android Beacon Library的扫描速率，以使其有更多时间来收集信标数据包。默认情况下，它使用1.1秒的扫描周期。您可以使用下面的代码行将其减慢到5秒。对于不经常做广告的信标，这将更可靠地工作，但也会使您对区域条目/出口的响应时间变慢。 beaconManager.setForegroundScanPeriod(5000l);
