可以使用android-beacon-library提供的方法来获取iBeacon的服务数据。具体步骤如下：

1. 首先，您需要在iBeacon的筛选器中添加服务UUID。示例代码如下：

private static final String IBEACON_FORMAT = "IBeacon (proximityUUID:major:minor)";
private static final String[] IBEACON_SCAN_FILTERS = { "m:2-3=0215", "i:4-19" };

//添加服务UUID
private static final String[] IBEACON_SCAN_FILTERS_WITH_UUID = {
            "m:2-3=0215",
            "i:4-19",
            "s:20-21=UUID",
            "s:22-23=UUID",
            "s:24-25=UUID",
            "s:26-27=UUID"};

//设置服务UUID
private static final String SERVICE_UUID = "E2C56DB5-DFFB-48D2-B060-D0F5A71096E0";

2. 然后，在onBeaconServiceConnect()回调方法中添加以下代码：

@Override
public void onBeaconServiceConnect() {
    beaconManager.setRangeNotifier(new RangeNotifier() {
        @Override
        public void didRangeBeaconsInRegion(Collection beacons, Region region) {
            for (Beacon beacon : beacons) {
                //获取服务数据
                byte[] serviceData = beacon.getServiceData();
                if (serviceData != null) {
                    //解析服务数据
                    parseServiceData(serviceData);
                }
            }
        }
    });

    try {
        //开始范围查找
        beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null));
    } catch (RemoteException e) {
        e.printStackTrace();
    }
}

3. 最后，在parseServiceData()方法中解析服务数据。以下是示例代码：

private void parseServiceData(byte[] serviceData) {
    if (serviceData.length > 3) {
        //获取服务UUID
        String uuid =
