Android Gets the implementation code for the IP address of the mobile phone _android

1. Get the phone 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 ());

2. The complete code is as follows:

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; 
 }

Get the current IP address of the Android phone

public class Networkutils {/** * Check whether the network is available * * @param paramcontext * @return */public static Boolean check
		Enable (Context Paramcontext) {Boolean i = false; Networkinfo Localnetworkinfo = (connectivitymanager) paramcontext. Getsystemservice ("Connectivity").
		Getactivenetworkinfo ();
		if (localnetworkinfo!= null) && (localnetworkinfo.isavailable ()) return true;
	return false; /** * Converts the integer form of IP to IP form * * @param ipint * @return/public static String int2ip (int ipint) {Stringbuild
		ER sb = new StringBuilder ();
		Sb.append (Ipint & 0xFF). Append (".");
		Sb.append ((Ipint >> 8) & 0xFF). Append (".");
		Sb.append ((Ipint >>) & 0xFF). Append (".");
		Sb.append ((Ipint >>) & 0xFF);
	return sb.tostring ();
		/** * Get Current IP Address * * @param context * @return/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 ();
			}//}//} Wifimanager Wifimanager = (wifimanager) context. Getsystemservice (Context.wifi_service);
			Wifiinfo wifiinfo = Wifimanager.getconnectioninfo ();
			int i = wifiinfo.getipaddress ();
		return Int2ip (i); The catch (Exception ex) {return] gets an IP error bird!!!!
		Please make sure it is WiFi, or please reopen network!\n "+ ex.getmessage ();
	}//return null; }
}

Get native IP address and MAC address in Android

by Inetaddress.getlocalhost () is always "127.0.0.1", to get the real network IP address through the following method:

First create a new project, modify the Androidmanifest.xml file to increase user rights, as follows:

Copy Code code as follows:

<uses-permission android:name= "Android.permission.INTERNET"/>//must write
<uses-permission android:name= "Android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name= "Android.permission.CHANGE_NETWORK_STATE" ></uses-permission>
<uses-permission android:name= "Android.permission.ACCESS_WIFI_STATE" ></uses-permission>//must write
<uses-permission android:name= "Android.permission.CHANGE_WIFI_STATE" ></uses-permission>

The main function code is as follows:

Get native IP address public string Getlocalhostip () {String ipaddress = "";
   try {enumeration<networkinterface> en = networkinterface. getnetworkinterfaces (); Traverse the network interface used while (En.hasmoreelements ()) {NetworkInterface nif = en.nextelement ();//Get all IP enums bound by each network interface
    Eration<inetaddress> inet = nif.getinetaddresses ();
     Traverses all IP while (inet.hasmoreelements ()) {inetaddress IP = inet.nextelement () for each interface binding;
      if (!ip.isloopbackaddress () && inetaddressutils.isipv4address (IP. gethostaddress ())) {
     return ipaddress = "The IP of this machine is" + ":" + ip.gethostaddress ();
   catch (SocketException e) {log.e ("Feige", "Get local IP address failed");
  E.printstacktrace ();

 return IPAddress;
  //Get native MAC address public string Getlocalmac () {String mac = "";
  Get WIFI manager Wifimanager wifimng = (wifimanager) getsystemservice (Context.wifi_service);
  Wifiinfo wifiinfor = Wifimng.getconnectioninfo (); MAC = "The MAC address of this machine is:" + wifiinfor.getmacaddress ();
 return mac; }

Android access to wifi IP address

Wifimanager wifimanage= (Wifimanager) Context.getsystemservice (context.wifi_service);//Get WifiManager 
 
// Check to see if WiFi opens if 
 
(!wifimanage.iswifienabled ()) { 
wifimanage.setwifienabled (true); 
} 
 
Wifiinfo wifiinfo= wifimanage.getconnectioninfo (); 
String Ip=inttoip (Wifiinfo.getipaddress ()); 
 
Convert the obtained int to a real IP address, refer to the Web, modify the next 
 
private String inttoip (int i) {return
(I & 0xFF) + "." + ((I >> 8) &A mp 0xFF)? + "." + ((I >>) & 0xFF) + "." + ((i >>) & 0xFF);

OK, is that good? Oh, don't forget to add permission

Copy Code code as follows:

<uses-permission= "" Android:name= "Android.permission.ACCESS_WIFI_STATE" ></uses>
<uses-permission= "" Android:name= "Adnroid.permission.CHANGE_WIFI_STATE" ></uses>

Summary: You can compare, Android access to mobile phone IP address method, so as not to create unnecessary problems in the process of programming.
