[AC Question]

A friend was trying to give me directions to where she was, I was wondering, since they can locate a person while his phone is on (providing he has his location app installed/turned on/active), is there a way to navigate to the person I'm talking to, android to android?

If they use Hangouts (and maybe other messaging apps), they can send you their location that way. If they're on G+, they can enable to share their location with you then you can find where they are through G+. While you're actually talking on the phone, it's not so easy.
