I am developing a backup application for Android, mainly contacts and SMS messages. Backing up isn't a problem, but writing the contacts back to the Android database is proving problematic.
This is what I have so far:
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI)
.withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, null)
.withValue(ContactsContract.RawContacts.ACCOUNT_NAME, null)
.build());
ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, 1)
.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
.withValue(StructuredName.GIVEN_NAME, "Joe")
.withValue(StructuredName.FAMILY_NAME, "Bloggs")
.build());
ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID,1)
.withValue(ContactsContract.Data.MIMETYPE,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)
.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, "086555555")
.withValue(ContactsContract.CommonDataKinds.Phone.TYPE,ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)
.build());
try{
ctx.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
}catch(Exception e){
e.printStackTrace();
}
It all seems to hinge on the RAW_CONTACT_ID. I'm using the emulator, with no contacts at the start. It works for the first contact creation(RAW_CONTACT_ID = 0), but no contacts seem to be created after that initial one, where RAW_CONTACT_ID is 1 upwards. Anybody got any ideas as to how this is the case?
