android4.0 獲取手機IP地址的問題

 獲取手機IP地址的代碼：

public static 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 e) {
			// TODO: handle exception
			Utils.log("WifiPreference IpAddress---error-" + e.toString());
		}
		
		return null; 
	}

但是在4.0 下 會出現類似fe80::b607:f9ff:fee5:487e的IP地址， 這個是IPV6的地址，我們需要獲得是的IPV4的地址，所以要在上訴代碼中加一個判斷

InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())

完整代碼如下：

public static 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() && InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())) {  
	                        
	                    	return inetAddress.getHostAddress().toString();  
	                    }  
	                }  
			 }
		}catch (SocketException e) {
			// TODO: handle exception
			Utils.log("WifiPreference IpAddress---error-" + e.toString());
		}
		
		return null; 
	}
