Lab 3: Due Tuesday, October 12 at the beginning of class

1. Pick a new partner - not anyone that you worked with in the past.
2. With your partner, complete all parts of the following:
• Map Tour
• Map Tour - Part 2
• Android, Where's My Car?
• Create a new app that is similar to Map Tour - Part 2, but adds the following:
• Show the Cal Poly map image (from http://maps.calpoly.edu/images/Core.gif) in place of the Paris map image
• Create three list pickers with labels: "Choose Building", "Choose Origination", and "Choose Destination"
• Your screen should look something like this:
  
• When the user clicks any of the list pickers the choices should be the following: Computer Science, University Union, Library, a building of your choice on the Cal Poly campus
• When the user selects a building through "Choose Building", go to the corresponding location in Google maps (similar to Map Tour - Part 2)
• When the user selects both an origination and a destination through "Choose Origination" and "Choose Destination", show the corresponding directions in Google maps (similar to Android, Where's My Car?)
• Make the "Choose Destination" button disabled until the user chooses a building through "Choose Origination".
• Only enter the coordinates for a location once; this will involve changing (refactoring) the dataURIs list; use these coordinates to construct the strings that you send to Google Maps both for showing a destination and for getting directions
• Create two procedures that return values, one called "BuildBuildingString" and one called "BuildDirectionsString"
• Demo your app to Dr. Janzen in lab
3. On your own, on your lab 3 page in your e-portfolio,
• declare who you worked with
• paste in an image of your solution from the Blocks Editor
• Answer the following question:
• Suppose you were provided three functions that retrieved 1) a list with an unknown number of buildings, 2) a corresponding list of longitude coordinates, and 3) a corresponding list of latitude coordinates from the web.
• Would you need to modify your two functions "BuildBuildingString" and "BuildDirectionsString", or the code that calls these functions?
• Describe what else you would modify in your app to use these functions to make the building list from the web available to the user.
