Yes.
Most apps ask explain to the user what is about to happen, and why it is important they allow it. And if the user feels this makes sense, they press a button to show the formal request. But it's not shown until the user has indicated that they actually would agree to it. So, to explain in a slightly different way: Before actually requesting the permission, show your own info where you ask if it's ok to request the permission.
I hope that was clear enough.
