我正在使用 altbeacon 库 2.15+ 但对于 oreo 和 nougat 版本不是扫描信标?

I am using altbeacon library 2.15+ but for oreo and nougat version is not scanning beacon?

onBeacon ServiceConnect 方法是检测beacon。对于棒棒糖版本正在检测牛轧糖和奥利奥版本信标未检测: public void onBeaconServiceConnect() {

    RangeNotifier rangeNotifier = new RangeNotifier() {
        @Override
        public void didRangeBeaconsInRegion(Collection<Beacon> beacons, org.altbeacon.beacon.Region region) {
            Log.d(TAG, "in didRangeBeaconsInRegion " + beacons.size());
            if (beacons.size() > 0) {
                Log.d(TAG, "didRangeBeaconsInRegion called with beacon count:  " + beacons.size());
                for (Iterator<Beacon> iterator = beacons.iterator();
                     iterator.hasNext(); ) {
                    Beacon beacon = iterator.next();

                    if (beaconlist.size() > 0) {
                        Log.d(TAG, "List Size :" + beaconlist.size());
                        for (int i = 0; i < beaconlist.size(); i++) {
                            Log.d("BeaconList ", beaconlist.get(i));
                        }
                    }

                    if (!beaconlist.contains(beacon.getId1().toString())) {
                        Log.d(TAG,"In get APi");
                        getApi(beacon.getId1().toString());
                        beaconlist.add(beacon.getId1().toString());
                        Log.d(TAG, "Notify in dead state");
                        Log.d("Notify in dead state", beacon.getId1().toString());
                    }
                }
            }
        }
    };
    try {
        Log.d(TAG, "I am in startRangingBeaconsInRegion");
        beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null));
        beaconManager.addRangeNotifier(rangeNotifier);
    } catch (RemoteException e) {
        e.printStackTrace();
    }
}

这是我的代码,任何人都可以解决这个问题。

要检查两件事:

  1. 您是否已将 COARSE_LOCATION 权限添加到您的 AndroidManifest.xml 并添加代码以在运行时动态地从用户那里成功获取该权限?

  2. 您是否成功构建了 BeaconManager、调用 bind(...) 并确认您在开始测距之前收到了 onBeaconServiceConnect() 的回调?如果不这样做,您将在尝试开始测距时收到 RemoteException。使用 Log.e(TAG, "Not bound to beacon scanning service")

  3. 将此异常记录到 LogCat 是个好主意
