1. scanRecord should be parsed as a list of AD structures.
2. iBeacon is a kind of AD structures.

With nv-bluetooth, you can extract iBeacon like the following.

public void onLeScan(BluetoothDevice device, int rssi, byte[] scanRecord)
{
    // Parse the payload of the advertising packet.
    List structures =
        ADPayloadParser.getInstance().parse(scanRecord);

    // For each AD structure contained in the advertising packet.
    for (ADStructure structure : structures)
    {
        if (structure instanceof IBeacon)
        {
            // iBeacon was found.
            IBeacon iBeacon = (IBeacon)structure;

            // Proximity UUID, major number, minor number and power.
            UUID uuid = iBeacon.getUUID();
            int major = iBeacon.getMajor();
            int minor = iBeacon.getMinor();
            int power = iBeacon.getPower();

            ........

See "iBeacon as a kind of AD structures" for details.
