//The IMEI: 仅仅只对Android手机有效:

//Pseudo-Unique ID, 这个在任何Android手机中都有效
String m_szDevIDShort = "35" +

// if it is a single digit, make sure it have 0 in front (proper padding)
if (b <= 0xF)
                m_szUniqueID+="0";
// add number to string

}   // hex string to uppercase

String m_szLongID_out = m_szImei + "*****" + m_szDevIDShort
                + "*****" + m_szAndroidID + "*****" + m_szWLANMAC + "*****" + m_szBTMAC;

uuid.setText(m_szLongID_out + "---" + m_szUniqueID);

}
}

xml文件里面加下权限：

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