Retrieve Phone Number In Android

This is the following code to retrieve phone number wwas able to get it on samsung 4.0.4, but getting below error on htc one v mobile..any clue? public void onCreate(Bundle savedIn

Solution 1:

TelephonyManager mTelephonyMgr;
mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
StringmblNumber= mTelephonyMgr.getLine1Number();

Note: Dont forget to add READ_PHONE_STATE permission to be added inside the AndroidManifest.xml file:

<uses-permissionandroid:name="android.permission.READ_PHONE_STATE"></uses-permission>

Solution 2:

According to the documentation .getLine1Number() "Returns the phone number string for line 1, for example, the MSISDN for a GSM phone. Return null if it is unavailable. "

Apparently .getLine1Number() reads this information from SIM card, so if the operator has set the MSISDN field it will return you its value and null if they did not set this field.

In your case probably your SIM card does not have this field populated by operator.
