Note: achievements may not pop immediately, or may not show as having popped. Look at the achievement button in the game to see.

You're going to want to go here to his dropbox for achievement worlds:https://www.dropbox.com/sh/qeswcgkt6pah7aa/AACrIRqqZB5OrysSM...
Once you've unzipped it, go to on your device and open the folder: /sdcard/games/com.mojang/minecraftWorlds
(If you are running this off your phone, leave just look for the games folder in the root directory.)
Open the unzipped folder. You'll see another folder. Move this into the minecraftWorlds folder. Yes, copy all the files when it asks. Now play the world.
You should start with a very weak Ender Dragon above you. If you like (and it's a good idea to do now), use a potion in your inventory to get a glass bottle and capture some Dragon Breath for this:
Kill the dragon. If you don't already have it, you'll get this:
Then jump into the End Portal, getting this:
Skip the credits by pressing A twice. Note: Unless you feel like killing the Ender Dragon again, make sure to do other achievements in the world before going back through the portal, or you'll have to move a fresh world back from your PC.
Now go back to the End Portal. Make sure you have a pickaxe and 4 End Crystals. (You should start with them.) Jump through, climb to the top and go forward until you see the teleporter. Don't jump in. Instead, place one End Crystal in the center of each of the four sides of the teleporter. It should look like this: (X = crystal, O = other blocks)
...and there's the dragon!
