@boardtc On Android the contacts list is compiled from so called raw contacts (every account has its own contacts - for example whatsapp has a duplicated list of contacts). An algorithm tries to merge these contacts (it’s duplicates) into one visible contact for you (you can see this when editing a contact - then you’ll see connections to Whatsapp, Signal, Threema, etc). Maybe you assigned a picture into another raw contact of a not-DAVx5-account. Then you might not see the picture you attached to this contact when you pull that contact out for quick use. However it should work with contact picture - I just tested it on a Samsung device.
After adding lombok-api.jar to the project, Eclipe doesn’t recognized. How can I proceed ?
