Hello folks, I'm building backup\restore software for contacts using Android 2.1, I understood the structure; I mean the relation between Contact, RawContact, and Data. http://developer.android.com/resources/articles/contacts.html
I checked the database (contacts2.db) and after studying it I found: 1- when you delete a contact; its row from contact table is deleted. 2- Its (Raw contact) rows remain as they were, but the (RowContact.contact_id) will be set as null (break the relation with Contact table) and the flag (RowContact.deleted) is set as 1. 3- Also its (Data) rows remain as they were,but the (RowContact.contact_id) will be set as null (break the relation with Contact table). My questions: 1- Under which criteria Android reverts or reattach a contact id with a raw contact rows? 2- Do you see that this is security breach since I can buy a second hand Android phone and query the contact database and see all the (Deleted Contact) data? 3-Under which criteria we can get (Contact has more that one raw contact) attach to it? I found the feature (Link) so you can link more than one contact together, is there any other feature that creates (contact with more than raw contact) scenario ? 4-What is the best way to identify that a contact has been changed? currently I'm using (RawContact.version) to track if there is a change on a raw contact.
