Android 关于三星设备关闭屏幕无法扫描到BLE的问题

如果使用的是 org.altbeacon:android-beacon-library:2.17.1 出现了三星设备再关闭屏幕后 didRangeBeaconsInRegion();返回的 beacons.size 等于 0

https://github.com/AltBeacon/android-beacon-library/issues/933

解决办法：

        beaconManager = BeaconManager.getInstanceForApplication(this);

        beaconManager.getBeaconParsers().clear();

        int[] hardwareAssistManufacturers =new int[]{0x01QP};// add dock Manufacturer Data.

            ‘0x01QP’是硬件设备蓝牙的Manufacturer Data.  需要设置这个过滤条件，否则锁屏后三星设备将无法callback BLE broadcast.

        BeaconParser beaconParser =new BeaconParser().setBeaconLayout(Collocation.IBEACON_LAYOUT);

        beaconParser.setHardwareAssistManufacturerCodes(hardwareAssistManufacturers);

        beaconManager.getBeaconParsers().add(beaconParser);
