Contact update Fehler "Source not found"

[anroid]

        Cursor phoneCursor = contentResolver.query(PhoneCONTENT_URI, null,
                Phone_CONTACT_ID + " = ?", new String[] { contactId }, null);
        List<String> result = new ArrayList<String>();
        while (phoneCursor.moveToNext()) {
            result.add(phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER)));
        }
        ContentValues values = new ContentValues();
        values.put(NUMBER, "0000000");
        contentResolver.update(PhoneCONTENT_URI, values,  Phone_CONTACT_ID + " = ?", new String[] { contactId });
// FEHLER SOURCE NOT FOUND

Manifest:
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />

Ich kann die Daten lesen, aber die Telefonnummer kann ich nicht updaten :-(

Stimmen die API targets und die Libs?

Ansonsten: CatLog or GTFO.
