I have an app that gets the ContactsContract.Contacts.LOOKUP_KEY of a contact on the device and saves it on the app Db.
After reading this page I thought I could use the LOOKUP_KEY to uniquely identify a contact, even when a contact is edited (for example after editing the name of the contact).
Actually I saw that after editing a contact, its LOOKUP_KEY changes, so I cannot use anymore the LOOKUP_KEY I saved on my app DB.
My question is: is there a way to uniquely identify a contact on ContactsContract.Contacts from when it is created for the first time on the device until it is deleted from the device?
Thank you
