Android:
I will be accessing the Twitter restful API [1] with my Android app and get the tweets in my case I will search trending hashtag for example (#android) and get the a certain number of tweets[2], display them in a scroll able view, and the draw a graph based on their location or frequency of these tweets. The Twitter API's response format is JSON, and OAuth authentication is required [3] in order to access their web service. A mockup of my planned design is available [4]
