How to play multiplayer on minecraft pe 0.8.0?

Unfortunately, you have to register an account through the settings and pay.

I have minecraft pe on my android and i saw that there's no realms in the new update which is the 0.8.0. But you can still do multiplayer by doing this thing. Example: You and your friend are connected to the same Wi-Fi and your friend is playing his/her world. And you want to join him/her. His/her world will automatically show up on your world list. How can you be sure that, that is his/her world? The text is in Blue color in your world list.
Your welcome.

Look on the Internet for a external sever and click edit on game as you were deleting world then click external and change the ip to the one you found on the Internet.
