What happens when someone gets served an afa davit?

I have an injunction against my ex boyfriend. One day when I got home I noticed that my ex was outside of my house within feet in which he is court ordered to be ft away from the address. When the cops got to my house they said they couldnt fo anything because he told the cops that he was going to visit his boss. He clearly lied to the cops. His boss lives houses down from me... The cops and I went down to his boss' house to make sure it was true. His boss said he was home all day and has not seen him. He even said that my ex called out that day.... When the cops returned to my house they said they were going to go to my exboyfriends house and give him an afa davit... Im not sure what that means... is he going to be put in jail for violation of a restraining order... or is he going to court?? I dont understand. someone please help me !
