We use anyway to contrast reasons or situations that have already been mentioned. It is usually used in end position:
[a couple are about to go for a walk]
A:Is it raining, Greg?
B:No, but bring a coat anyway. It might rain. (Bring a coat in spite of the fact that it is not raining now.)
A:You’re going on holiday tomorrow, aren’t you?
B:Yeah. We’re going camping. Brian’s idea, not mine!
A:I’m sure you’ll enjoy it anyway. It’ll be fun. (You’ll enjoy it in spite of the fact that you don’t really like camping.)
