A good way to remotely control your raspberry pi using Android is to follow this tutorial http://www.neil-black.co.uk/raspberry-p ... sdPNrQ7mNI, and then download the androidVNC app off the play store. Run the app and this is what you need to tell it. PS. (you don't need to do any of the windows parts of the tutorial unless you want to remote in from windows as well as your android device)
Nickname: raspberry:1
Password: What ever you was asked to set during the raspberry pi tightVNC tutorial
Address: The IP address of your raspberry pi
port: 5901
Type all that in and hit connect and you are in.

Works well on larger phones/tablets.
