You cannot avoid this issue. The user should give your app the required permission.
hello,
thank you for the advice.
I think it is very heavy implementation.
I'm trying to develop a project to track invitations (date, location, contacts, meals etc ...)
So I want to recover contacts gmail or another to put them in a database for my project
it is also necessary to synchronize, yet to my project.
I would also like to give to other users, but with their own contact lists.
I hope I described my project
can you give me a track
best regards
