我正在编写代码来获取任何版本高于 2.3 的 Android 设备的 MAC 地址。一般来说，我在 HiActivity.java 中编写了以下代码：
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();
}
}
而不是在 Eclipse 中以调试模式给出任何输出 它在 LogCat 中给出以下内容

我的代码错误在哪里？我尝试调试但无法找到我的错误。
/*getMAC() 方法返回 MAC 地址 */
public String getMAC() {
WifiManager wifiMan = (WifiManager)AppUtils.mContext.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInf = wifiMan.getConnectionInfo();
String macadd=wifiInf.getMacAddress();
System.out.println("MAC address info---- "+macadd);
if(macadd==null){
macadd="1A:DC:5C:8E:15:7B";
}
return macadd;
}
使用
android.telephony.TelephonyManager.getDeviceId()同时在清单中设置
READ_PHONE_STATE
