I got a new phone and I was wondering if I could transfer minecraft to my new phone?

On my old phone I had minecraft but I got a new phone and I wanna transfer minecraft on to my new phone. How do you do this? Simple instructions please.

It depends.
Do you have a IPhone or a Android Phone.

If it's Android
Go to play store, login to your gmail account and download from there.

if it's IPhone
Log in to your Itunes account and download from there

Sadly, if it's something like Android to IPhone, You're out of luck
