Write an Android application

Hey guys, I have purchased an Android Recipe application off of envato that I've modified a bit. I don't exactly know what's going on (some of it's straight forward, so I can figure that out), so I'm unsure of how to add further functionality that I'd like for my application. Here is the link to the template I have purchased: [login to view URL] -- That means I also have the ability to download an unmodified copy if need be. By modifying, I haven't done too much, just like added/changed some pictures and themes. I'd like to add the following functionalities to it though if someone is willing to help or discuss: Grocery List - pretty self explanatory, I would like for people to be able to create a grocery list (maybe even the ability to make multiple). It currently has the functionality of exporting a recipes ingredients to a text message, so would love for that to export to the grocery list also/instead. Rating System - Rate the recipes on a scale of 1-5 and then sort/search based off of top rated recipes Would love for the program to be documented better (or at least what you add) so I can figure out the rest of what's going on! If you're interested in this project make sure "Let's make a recipe" is in your proposal - or it'll have been made clear to me that you didn't really read through my post. I would like this completed by Thursday if possible! I don't think it's much to add, but I suppose I'm not sure :P
