Android Get IP Address

In this post, you can learn android source code to fetch the internet network IP address of the android device. Create a new android project and then in the main activity update the below code units.

ActivityMain.java

package com.udhaya.ip;

import java.net.InetAddress;

import java.net.NetworkInterface;

import java.util.Enumeration;

import android.app.Activity;

import android.os.Bundle;

import android.util.Log;

import android.widget.TextView;

public class MainActivity extends Activity {

 @Override

 protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);

  try {

   for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {

              NetworkInterface intf = en.nextElement();

              for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {

                  InetAddress inetAddress = enumIpAddr.nextElement();

                  if (!inetAddress.isLoopbackAddress()) {

                  TextView ipView= (TextView) findViewById(R.string.ip);

                  ipView.setText(inetAddress.getHostAddress());

                  }

              }

          }

  } catch (Exception e) {

   Log.e("------------", e.toString());

  }

   }

}

Also, in the android manifest file, update the Uses Permission as mentioned below.

       

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