Android: Manage contacts with lookup key

Question

I\'m currently writing a application that allows to save drafts (using android version >= 2.0). Each draft is connected to a contact via the ContactsContract.Contacts.

Answer 1

It is my understanding that the lookup key is a structured / hierarchical key. Hence strictly speaking it can change, but still be used to find your contact back, by using the appropriate method:

    Uri lookupUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
    Uri res = ContactsContract.Contacts.lookupContact(getContentResolver(), lookupUri);
