Android设备的唯一标识

Android设备，由于生产厂家五花八门，各种标示不一定对所有的Android设备都起作用，手机和平板就有区别，为了能够准确的区分不同的Android设备，可以使用下面的类来唯一的标示一个Android设备：

UpLoadDeviceToken.java

package com.mxd.deviceToken;

import java.io.InputStream;

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

import java.util.ArrayList;

import java.util.List;

import android.annotation.SuppressLint;

import android.bluetooth.BluetoothAdapter;

import android.content.Context;

import android.net.wifi.WifiManager;

import android.os.Build;

import android.provider.Settings.Secure;

import android.telephony.TelephonyManager;

publicclassUpLoadDeviceToken

{

Context context;

publicUpLoadDeviceToken(Context context)

{

this.context =context;

}

/**

* @param context

* @return 将5种获得设备唯一标示的String拼接，并进行MD5加密

@SuppressLint("DefaultLocale")

privateStringgetDeviceToken()

{

Stringm_szImei = getSZImei();

Stringm_szDevIDShort = getSzDevIDShort();

Stringm_szAndroidID = getAndroidID();

Stringm_szWLANMAC = getSzWLANMAC();

Stringm_szBTMAC = getSzBTMAC();

Stringm_szLongID =m_szImei +m_szDevIDShort + m_szAndroidID + m_szWLANMAC + m_szBTMAC;

MessageDigestm =null;// compute md5

try

{

m =MessageDigest.getInstance("MD5");

}catch (NoSuchAlgorithmExceptione)

{

e.printStackTrace();

}

m.update(m_szLongID.getBytes(),0,m_szLongID.length());

bytep_md5Data[] =m.digest();// get md5 bytes

Stringm_szUniqueID =new String();// create a hex string

for (inti =0; i <p_md5Data.length;i++)

{

intb = (0xFF &p_md5Data[i]);

if (b <=0xF)

m_szUniqueID +="0";

m_szUniqueID +=Integer.toHexString(b);

}

m_szUniqueID =m_szUniqueID.toUpperCase();

returnm_szUniqueID;

}

/**

* <uses-permission

privateStringgetSZImei()

{

StringszImei ="";

TelephonyManagerTelephonyMgr = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

if (TelephonyMgr.getDeviceId() !=null && !TelephonyMgr.getDeviceId().equals(null))

{

szImei =TelephonyMgr.getDeviceId();// Requires READ_PHONE_STATE

}

returnszImei +"";

}

/**

privateStringgetSzDevIDShort()

{

StringszDevIDShort ="35" +// we make this look like a valid IMEI

Build.BOARD.length() %10 +Build.BRAND.length() %10 +Build.CPU_ABI.length() %10 +Build.DEVICE.length() %10//

+Build.MODEL.length() %10 + Build.PRODUCT.length() %10 +Build.TAGS.length() %10 +Build.TYPE.length() %10//

+Build.USER.length() %10; // 13_digits

returnszDevIDShort +"";

}

/**

* @return Android ID , 通常被认为不可信，因为它有时为null,无需任何许可

privateStringgetAndroidID()

{

Stringm_szAndroidID ="";

if (Secure.getString(context.getContentResolver(),Secure.ANDROID_ID) !=null &&

!Secure.getString(context.getContentResolver(),Secure.ANDROID_ID).equals(null))

{

m_szAndroidID =Secure.getString(context.getContentResolver(),Secure.ANDROID_ID);

}

returnm_szAndroidID +"";

}

/**

privateStringgetSzWLANMAC()

{

Stringm_szWLANMAC ="";

if (wm.getConnectionInfo().getMacAddress() !=null && !wm.getConnectionInfo().getMacAddress().equals(null))

{

m_szWLANMAC =wm.getConnectionInfo().getMacAddress();

}

returnm_szWLANMAC;

}

/**

{

}

returnm_szBTMAC;

}

/////////通过上面设置的4个标准值，就可以比较准确的唯一标示一台Android设备了。
