I use contact _ID to store specific informations about contacts in my application DB. But I've just test to
- remove a contact "BOB" (_ID=7)
- create a new contact
=> the new contact "John" has the _ID=7, same as deleted "Bob" .
The _ID is not an real unique ID and I can't use it.
1 - Do a Intent is broadcasted when a contact is deleted ?
2 - Do a real unique ID exists for a contact ?
