Get telephone number of device

Question

I am making an app in which I have to get the mobile number of the GSM device and I used the following code to show to phone no in a TextView, but all in vain. Can anyone help me do this.

TelephonyManager mTelephonyMgr;
    mTelephonyMgr = (TelephonyManager)
        getSystemService(Context.TELEPHONY_SERVICE);

    String number = mTelephonyMgr.getLine1Number();

    Phoneno=(TextView)findViewById(R.id.Phoneno);


    Phoneno.setText(number);

Most phones just return null for getLine1Number(). As far as I know, there is no way to get the active phone-number from code. — Jave, Dec 21 '11 at 13:02
I've been searching and it depends on each mobile , some send null some sends the real number. It seems to not have a good way to get it. — A.Quiroga, Dec 21 '11 at 13:05
Dr.nik , i have used that permission but it returned nothing — , Dec 21 '11 at 13:10
It means that i have not seen a way to have the number in all phones . But there must be one . Try searching harder. — A.Quiroga, Dec 21 '11 at 13:13
I'm having the same problem. It doesnt even return null. It just returns an empty string — Saurabh Verma, Dec 21 '11 at 13:15

TelephonyManager.getLine1Number() is the only solution available till now.Actually sim does not contains info about the number .It is delivered by the network only.Also this is sim dependent .For some device it (TelephonyManager.getLine1Number()) will work.For some it may not.
