You need to set the MCC )(Mobile Country Code) and MNC (Mobile Network
Code) values too in your code to set and display the APN's on Android UI.
Try the following code and see what happens:
>
> *private static* *final* Uri *PREFERRED_CONTENT_URI* = Uri.*parse*(
> "content://telephony/carriers/preferapn");
>
>
>
> // getCurrentPreferredAPN is an internal function to retrieve the "_id" of
> the current APN.
> String strCurrent = getCurrentPreferredAPN();
>
> ContentValues values = *new* ContentValues();
>
> Uri ret;
>
String MCC = null, MNC = null;
TelephonyManager tel = (TelephonyManager)
getSystemService(this.TELEPHONY_SERVICE);
String networkOperator = tel.getNetworkOperator();
if (networkOperator != null) {
MCC = networkOperator.substring(0, 3);
MNC = networkOperator.substring(3);
}
>
>
// create the dummy ID
>
> values.put(*SZ_NAME*, *"blah"*);
> values.put(*SZ_APN*, *"blah"*);
>
> values.put(*SZ_TYPE*
> , *"blah"*);
>
> values.put("current", "1");
>
> values.put("mcc", MCC);
> values.put("mnc", MNC);
>
>
> // 'delete' the current entry.
> nUpdated = getContentResolver().delete(PREFERRED_CONTENT_URI, "_id=?",
> new String[] { strCurrent };
>
> // 'insert' a new entry.
> ret = getContentResolver().insert(PREFERRED_*CONTENT_URI*, values);
> *if*(*null* == ret)
>
> {
>
> Log.*i*("Add Dummy APN", "Failed");
>
> *return*;
>
> }
>
>
>
> The call ==> "insert"* ==>* is always returning null for me.
