This document discusses an app called Army Architect that was created to help summarize and track army lists for table-top war games. The app allows users to create customized army lists on their mobile device by parsing and writing XML files to automatically calculate point values and track units, solving problems of memorizing details and doing calculations by hand. The creators demonstrated a prototype of the app and discussed lessons learned around layout, activities, intents, custom list adapters, and using log cat for debugging.
