Android counterpart of iPhone app. Layout already designed.

We have already developed the iOS app and would like to make its Android counterpart. You will receive 2 documents: One with the layout designs (done with Balsamiq Mockups) and explanations of behavior for each of the app's windows, and another with API requests and code details for each window. App description It consists of 4 main windows: Search window which presents a list of results, Saved/Selling window which presents two separate lists of items you're selling and that you have saved from the search results list, Settings page with 1 setting and account info, and Help page which has 4 website links, an email link, and the Google Play store app link (the Rate Us link). Besides these four main windows, it has 4 supplementary ones: the register/login window, a mapView to select a location, the window when you're viewing items in detail, and the window when you are setting up the item for sale. Overall is a very straightforward app and all http requests made are to our API. Uses Facebook Login and the Mixpanel SDK for analytics. The details of where and what events to call for Mixpanel, and how to handle the Facebook Login calls are both included in the app details document you will receive.
