developed an app using a mobile phone used this code to pick imei number
Utill.class
static TelephonyManager telephonyManager;
public static String getDeviceID(){
telephonyManager=(TelephonyManager) MyApplication.getInstance().getSystemService(MyApplication.getInstance().TELEPHONY_SERVICE);
return telephonyManager.getDeviceId();
}
in my job.class
String imeino = Util.getDeviceID();
tested with mobile devises and it works properly but when apk installed a tab (in client side ) imei number does not pick and give a null pointer
Note. for tab i have added different layouts and it also works properly in my tab
is this a matter of base url or how can i avoid this issue of imei number ?
