获取设备唯一识别码跟Mac地址

获取设备唯一识别码和Mac地址

下面这个工具类提供了一些方法，可以获取设备AndroidID、IMEI、序列号、以及由他们组成的唯一识别码、网卡的MAC地址、蓝牙MAC地址。代码如下：

DeviceInfoUtil：

package com.home;

import java.util.UUID;

import android.bluetooth.BluetoothAdapter;
import android.content.Context;
import android.content.Intent;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.provider.Settings.Secure;
import android.telephony.TelephonyManager;

public class DeviceInfoUtil {

	/**
	 * 得到设备AndroidID，需要设备添加 Google账户
	 * 
	 * @param context
	 * @return
	 */
	public static String getAndroidID(Context context) {
		String androidID = Secure.getString(context.getContentResolver(),
				Secure.ANDROID_ID);
		return androidID;
	}

	/**
	 * 得到设备IMEI值
	 * 
	 * @param context
	 * @return
	 */
	public static String getIMEI(Context context) {
		TelephonyManager tm = (TelephonyManager) context
				.getSystemService(Context.TELEPHONY_SERVICE);
		return tm.getDeviceId();
	}

	/**
	 * 得到设备序列号
	 * 
	 * @param context
	 * @return
	 */
	public static String getSimSerialNumber(Context context) {
		TelephonyManager tm = (TelephonyManager) context
				.getSystemService(Context.TELEPHONY_SERVICE);
		return tm.getSimSerialNumber();
	}

	/**
	 * 得到设备唯一识别码
	 * 
	 * @param context
	 * @return
	 */
	public static String getUniqueNumber(Context context) {
		String androidID = getAndroidID(context);
		String imei = getIMEI(context);
		String simSerialNumber = getSimSerialNumber(context);
		UUID uuid = new UUID(androidID.hashCode(),
				((long) imei.hashCode() << 32) | simSerialNumber.hashCode());
		return uuid.toString();
	}

	/**
	 * 获取设备本身网卡的MAC地址
	 * 
	 * @param context
	 * @return
	 */
	public static String getWLANMACAddress(Context context) {
		String macAddress = "";
		WifiManager wm = (WifiManager) context
				.getSystemService(Context.WIFI_SERVICE);
		WifiInfo info = wm.getConnectionInfo();
		if (info != null) {
			macAddress = info.getMacAddress();
		} else {
			macAddress = "No Wifi Device";
		}
		return macAddress;
	}

	/**
	 * 获取蓝牙MAC地址
	 * 
	 * @param context
	 * @return
	 */
	public static String getBluetoothMACAddress(Context context) {
		String btMacAddress = "";
		BluetoothAdapter ba = BluetoothAdapter.getDefaultAdapter();
		if (ba != null) {
			if (!ba.isEnabled()) {
				btMacAddress = "Bluetooth not open";
				// 启动蓝牙
				Intent in = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
				context.startActivity(in);
			} else {
				btMacAddress = ba.getAddress();
			}

		} else {
			btMacAddress = "No Bluetooth Device";
		}
		return btMacAddress;
	}
}
