Android Studio WiFi 之 获取 WiFi 名称、IP、Mac_android studio 获取wifi名称

Android 获取连接的WIFI 的一些数据（后期封装成aar 包给Unity 调用）

封装成AAR包，获取 Android 7.0 以上的 手机 mac 地址

一、Android 代码

import android.app.Activity;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
 
import android.text.format.Formatter;
 
 
import java.net.InetAddress;
import java.net.NetworkInterface;
 
import java.net.SocketException;
import java.util.Enumeration;
 
import static android.content.Context.WIFI_SERVICE;
 
 
public class WifiMgr {
 
   /*
   *获取Mac地址
   *
   * android 7.0 以上使用*/
    public static String getMacAddress() {
        String strMacAddr = null;
        try {
            // 获得IpD地址
            InetAddress ip = getLocalInetAddress();
            byte[] b = NetworkInterface.getByInetAddress(ip)
                    .getHardwareAddress();
            StringBuffer buffer = new StringBuffer();
            for (int i = 0; i < b.length; i++) {
                if (i != 0) {
                    buffer.append(':');
                }
                String str = Integer.toHexString(b[i] & 0xFF);
                buffer.append(str.length() == 1 ? 0 + str : str);
            }
            strMacAddr = buffer.toString().toUpperCase();
        } catch (Exception e) {
        }
        return strMacAddr;
    }
    /**
     * 获取移动设备本地IP
     *
     * @return
     */
    private static InetAddress getLocalInetAddress() {
        InetAddress ip = null;
        try {
            // 列举
            Enumeration<NetworkInterface> en_netInterface = NetworkInterface
                    .getNetworkInterfaces();
            while (en_netInterface.hasMoreElements()) {// 是否还有元素
                NetworkInterface ni = (NetworkInterface) en_netInterface
                        .nextElement();// 得到下一个元素
                Enumeration<InetAddress> en_ip = ni.getInetAddresses();// 得到一个ip地址的列举
                while (en_ip.hasMoreElements()) {
                    ip = en_ip.nextElement();
                    if (!ip.isLoopbackAddress()
                            && ip.getHostAddress().indexOf(":") == -1)
                        break;
                    else
                        ip = null;
                }
 
                if (ip != null) {
                    break;
                }
            }
        } catch (SocketException e) {
 
            e.printStackTrace();
        }
        return ip;
    }
 
 

二、AndroidMainifest.xml 添加权限

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.INTERNET"/>

三、Unity 中调用

using UnityEngine;
 
/// <summary>
/// 通过IP，获取机器Mac地址
/// </summary>
public class GetWifiData 
{
    // 安卓的接口文档
    private AndroidJavaObject _androidJavaObject;
 
    public AndroidJavaObject mAndroidJavaObject {
        get {
            if (_androidJavaObject != null) {
                _androidJavaObject = new AndroidJavaObject("com.wifimacforarrow.pacificfuture.wifidataforarrow.WifiMgr");
            }
 
            return _androidJavaObject;
        }
    }
    /// <summary>
    /// 构造函数
    /// </summary>
    public GetWifiData() {
 
        _androidJavaObject = new AndroidJavaObject("com.wifimacforarrow.pacificfuture.wifidataforarrow.WifiMgr");
    }
 
    /// <summary>
    /// 获取设别的 Mac 地址
    /// </summary>
    /// <returns></returns>
    public string GetWifiMac() {
 
        
#if UNITY_EDITOR
        return "00:00:00:00:00:00";
#else
         return mAndroidJavaObject.CallStatic<string>("getMacAddress");
#endif
 
    }
}
