Android 获得本机ip地址和MAC地址
在清单文件中加入以下权限AndroidManifest.xml:
<!-- 访问Wi-Fi网络 -->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
获取Android本机IP地址和MAC，Test.java类:
package com.iaiai.test;import java.net.InetAddress;import java.net.NetworkInterface;import java.net.SocketException;import java.util.Enumeration;import android.content.Context;import android.net.wifi.WifiInfo;import android.net.wifi.WifiManager;import android.test.AndroidTestCase;import android.util.Log;public class Test extends AndroidTestCase {private final String TAG = "Test";public void testLocalIpAndMac() {Log.i(TAG, "IP: " + getLocalIpAddress() + ", MAC: "+ getLocalMacAddress());}/** * 获取Android本机IP地址 * * @return */private String getLocalIpAddress() {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()) {return inetAddress.getHostAddress().toString();}}}} catch (SocketException ex) {Log.e("WifiPreference IpAddress", ex.toString());}return null;}/** * 获取Android本机MAC * * @return */private String getLocalMacAddress() {WifiManager wifi = (WifiManager) this.getContext().getSystemService(Context.WIFI_SERVICE);WifiInfo info = wifi.getConnectionInfo();return info.getMacAddress();}}
