Hello.
I am trying to read and write contacts on the SIM phonebook.
First I tried writing a contact with GetContentResolver.insert(),
passing RawContacts.CONTENT_URI as URI and ensuring the column
RawContacts.ACCOUNT_NAME had the value "SIM", and adding 2 lines (1 for4
name and 1 for phone) to Data.CONTENT_URI, linked by contact ID. This
seemed to work: the contacts showed in the contact list with the SIM
logo next to them, but they wouldn't survive a reboot... apparently
that's just a placeholder in memory, which is synced with the real SIM
at startup and at every change.
Then I tried reading the list of contacs on the SIM with
Cursor cur = getContentResolver().query(
Uri.parse("content://icc/adn")
,null
,null
,null
,null
);
This fails with a NullPointerException on a real phone. On the emulator, it
returns a Cursor with 0 lines. This sounds likely.
Strangely, accessing content://icc/fdn and content://icc/sdn both work, both on
emulator and on phone.
Finally, I tried writing a contact with
ContentValues values = new ContentValues();
values.put("name","Name Of Contact");
values.put("number", "+777777777");
Uri uri = getContentResolver().insert(
Uri.parse("content://icc/adn")
, values)
;
This returns a null URI and no contact is inserted.
What's wrong there, and what's the right way of doing this?
Regards,
Fabrizio
