要在Android设备上连接到iBeacon，您可以使用Android Beacon Library。以下是一个示例代码，演示如何在Android设备上连接到iBeacon:

1. 首先，您需要在您的Android项目中添加Android Beacon Library依赖。您可以在项目的build.gradle文件中添加以下代码:

dependencies {
    implementation 'org.altbeacon:android-beacon-library:2.16.3'
}

2. 创建一个新的类，例如BeaconActivity.java，并在其中实现以下代码:

import android.Manifest;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.util.Log;

import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;

import org.altbeacon.beacon.Beacon;
import org.altbeacon.beacon.BeaconConsumer;
import org.altbeacon.beacon.BeaconManager;
import org.altbeacon.beacon.RangeNotifier;
import org.altbeacon.beacon.Region;

import java.util.Collection;

public class BeaconActivity extends AppCompatActivity implements BeaconConsumer {
    private static final int PERMISSION_REQUEST_FINE_LOCATION = 1;
    private BeaconManager beaconManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_beacon);

        // 检查并请求位置权限
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                    PERMISSION_REQUEST_FINE_LOCATION);
        } else {
            // 初始化BeaconManager
            beaconManager = BeaconManager.getInstanceForApplication(this);
            beaconManager.bind(this);
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        if (requestCode == PERMISSION_REQUEST_FINE_LOCATION) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // 初始化BeaconManager
                beaconManager = BeaconManager.getInstanceForApplication(this);
                beaconManager.bind(this);
            } else {
                // 没有授予位置权限，处理相应逻辑
            }
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        beaconManager.unbind(this);
    }

    @Override
    public void onBeaconServiceConnect() {
        final Region region = new Region("all-beacons-region", null, null, null);

        beaconManager.addRangeNotifier(new RangeNotifier() {
            @Override
            public void didRangeBeaconsInRegion(Collection beacons, Region region) {
                if (beacons.size() > 0) {
                    for (Beacon beacon : beacons) {
                        Log.i("Beacon", "UUID: " + beacon.getId1() +
                                " Major: " + beacon.getId2() +
                                " Minor: " + beacon.getId3() +
                                " RSSI: " + beacon.getRssi());
                    }
                }
            }
        });

        try {
            beaconManager.startRangingBeaconsInRegion(region);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

3. 在您的AndroidManifest.xml文件中添加以下权限:

4. 在您的AndroidManifest.xml文件中添加以下服务:

    ...
    
    
    ...

这样，您就可以在Android设备上连接到iBeacon并接收beacon数据了。当您在Android设备附近有iBeacon时，logcat会打印出beacon的UUID、Major、Minor和RSSI等信息。
