New contact creating rather than updating existing contact

Question

I am integrating my app with android default Contacts application.I would like to show an option \"xyz using MyApp\" inside every Contacts Detail.I am able to see my app in

Answer 1

in your addContact code you're missing the part that tells Contacts DB to join your new raw-contact into the existing contact, so that contact will now contain your raw-contact and your app-specific line will be shown when opening that contact in the contacts app.

Check this answer on how to join a RawContact into an existing Contact: why won't contacts aggregate?

You'll probably need to pass in some RawContact ID to your addContact method so it'll be able to join the two together.

UPDATE

Instead of applying the aggregation operation together with your RawContact insert operation, let's try to separate into two applyBatch calls, also, let's aggregate your new raw-contact with ALL existing raw-contacts, not just one of them. Try the following code, make sure you pass to it the existing contact-id (not raw-contact id) and your new raw-contact-id.

private void joinIntoExistingContact(long existingContactId, long newRawContactId) {

    // get all existing raw-contact-ids that belong to the contact-id
    List<Long> existingRawIds = new ArrayList<>();
    Cursor cur = getContentResolver().query(RawContacts.CONTENT_URI, new String[] { RawContacts._ID }, RawContacts.CONTACT_ID + "=" + existingContactId, null, null);
    while (cur.moveToNext()) {
        existingRawIds.add(cur.getLong(0));
    }
    cur.close();
    Log.i("Join", "Found " + existingRawIds.size() + " raw-contact-ids");

    List<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();

    // go over all existing raw ids, and join with our new one
    for (Long existingRawId : existingRawIds) {
        Builder builder = ContentProviderOperation.newUpdate(AggregationExceptions.CONTENT_URI);
        builder.withValue(AggregationExceptions.TYPE, AggregationExceptions.TYPE_KEEP_TOGETHER);
        builder.withValue(AggregationExceptions.RAW_CONTACT_ID1, newRawContactId);
        builder.withValue(AggregationExceptions.RAW_CONTACT_ID2, existingRawId);
        ops.add(builder.build());
    }

    contentResolver.applyBatch(ContactsContract.AUTHORITY, ops);
}

P.S.
don't open two duplicate questions, one is enough.

ANOTHER UPDATE

You seem to have some confusion about IDs.

There are Data IDs, RawContact IDs, and Contact IDs.

CommonDataKinds.Phone._ID will return a Data ID, identifying the specific row in the Data table in which that phone number is stored.

You can get a from the Phone table the other IDs as well, use: CommonDataKinds.Phone.RAW_CONTACT_ID CommonDataKinds.Phone.CONTACT_ID
