I am new on this so i do not find the answer on the internet or i am not sure if the answer is that. What i am trying to do is to make my app sync all the contacts in the native contact app like whatsapp or facebook does. I also wanted to link contacts. Any hint or tutorial would be great.
What are the benefits of putting my app over there? I am very new on this. Please I hope an answer do not vote down D:. Any answer is welcome.
