Android开发中获取本机Mac地址和IP地址的方法

1、Android 获取本机Mac 地址方法：



需要在AndroidManifest.xml文件中添加权限：

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

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

public String getLocalMacAddress() {

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);

WifiInfo info = wifi.getConnectionInfo();
return info.getMacAddress();

}

public String getLocalMacAddress() {
		WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
		WifiInfo info = wifi.getConnectionInfo();
		return info.getMacAddress();
	}

2、Android 获取本机IP地址方法：





public 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;

}
