android imei number for tablet
<p>In my application i have to get unique number of device for that i am using <code>TelephonyManager</code>.
I am able to get <code>imei</code> or <code>device id</code> in android phones but Is is possible for android tablet (Xoom) to <strong>get unique number</strong> ? 
I am using this code to get imei number but i am not able to get in tablet, <code>enter code here</code></p>

<pre><code>TelephonyManager telephonyManager1 = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
imei = telephonyManager1.getDeviceId();
</code></pre>
