android4.0 access to mobile phone IP address problem

To get the phone's IP address code:

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; 
	}

But in 4.0 there will be a similar fe80::b607:f9ff:fee5:487e IP address, this is the address of IPV6, we need to get the address of the IPV4, so to add a judgment in the appeal code

Inetaddressutils.isipv4address (Inetaddress.gethostaddress ())

The complete code is as follows:

 public static String getlocalipaddress () {try{for (ENUMERATION<NETWORKINTERFACE&G T En = Networkinterface.getnetworkinterfaces (); En.hasmoreelements ();)  
	                {NetworkInterface intf = en.nextelement (); for (enumeration<inetaddress> enumipaddr = intf. getinetaddresses (); Enumipaddr.hasmoreel Ements ();)  
	                    {InetAddress inetaddress = enumipaddr.nextelement ();  
	                        
	                    	if (!inetaddress.isloopbackaddress () && inetaddressutils.isipv4address (Inetaddress.gethostaddress ())) {  
	                    Return inetaddress.gethostaddress (). toString (); }}}catch (SocketException e) {//Todo:handle exception Utils.log ("Wifipreference Ip
		Address---error-"+ e.tostring ()); 
	return null; }
