I want to use phone number as user ID,so i want to access the phone
number.
in my code, i can get IMSI (International Mobile Subscriber Identity)
by using getSubscriberId().
but can not get MSISDN by using getLine1Number(),it returns null.
my test phone is HTC G3,
anybody can solve the problem?
thanks!
TelephonyManager tm = (TelephonyManager) getSystemService
(Context.TELEPHONY_SERVICE);
String phoneNumber = tm.getLine1Number();
if(phoneNumber == null || phoneNumber.trim().equals("")){
phoneNumber = "cann't get the phone number";
}
