I am writing code to get the mac address of any Android device having versions greater than 2.3. In general, I wrote the following code in HiActivity.java :
package com.hi.address;
import java.net.InetAddress;
import java.net.NetworkInterface;
import android.app.Activity;
import android.os.Bundle;
public class HiActivity extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void Display()
{
try {
InetAddress addresses = InetAddress.getByName(InetAddress.getLocalHost().getHostName());
NetworkInterface ni= NetworkInterface.getByInetAddress(addresses);
byte[] mac = ni.getHardwareAddress();
System.out.println("====="+mac);
for(int i=0; i< mac.length; i++)
{
System.out.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : "");
}
}catch(Exception e){
System.out.println("exception was occureddddddddd"+e);
}
}
public void onStart(Bundle savedInstanceState) {
System.out.println(" 999999999999999999999999");
Display();
}
}
Instead of giving any output in debugging mode in Eclipse
its giving the following in LogCat

Where is the error in my code? I am tried to debug but was no able to find my error.
Use
android.telephony.TelephonyManager.getDeviceId()to get uniquely identifier of the device (IMEI on GSM, MEID for CDMA).Also set
READ_PHONE_STATEpermissionin manifest
