Android 获取设备IP,已连接WiFi信息；（Android API-23: InetAddressUtils 替换）

获取本地IP

public static String getLocalIPAddress() {    String ip = "";    try {        for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces();            en.hasMoreElements();) {            NetworkInterface intf = en.nextElement();            for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses();                enumIpAddr.hasMoreElements();) {                InetAddress inetAddress = enumIpAddr.nextElement();                if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address){// Inetaddressutils.isIPv4Address(inetAddress.getHostAddress())) { API 19 以前可用                    ip = inetAddress.getHostAddress().toString();                    break;                }            }            if (!TextUtils.isEmpty(ip)) break;        }    } catch (Exception e) {        ip = "";    }    return ip;}

注：判断inteAddress 是否是IPV4时，在API 19 以前可以使用

Inetaddressutils .isIPv4Address(inetAddress.getHostAddress())

而在19以后则需要使用 inetAddress instanceof Inet4Address

已连接wifi信息

/*获取当前设备所连接wifi信息*/public static String  getMyWifiInfo(Context context){    String str = "";    WifiManager mWifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);    if (mWifi.isWifiEnabled()) {       // List<ScanResult> scanResults = mWifi.getScanResults();  //getScanResults() 扫描到的当前设备的WiFi列表        WifiInfo wifiInfo = mWifi.getConnectionInfo();        String netName = wifiInfo.getSSID(); //获取被连接网络的名称        String netMac =  wifiInfo.getBSSID(); //获取被连接网络的mac地址        String localMac = wifiInfo.getMacAddress();// 获得本机的MAC地址        int loalIP = wifiInfo.getIpAddress();        int level = wifiInfo.getRssi();        wifiInfo.getLinkSpeed();        str = wifiInfo.toString();    }    return  str;    }
