The document presents a mobile app called DSEDroid that was developed by a team to provide live stock market updates from the Dhaka Stock Exchange to shareholders. It discusses selecting Android as the platform, gathering requirements, implementing key modules like data scraping and parsing, and plans for commercializing the app and expanding it to other platforms. The development approach was agile iterative development. Challenges included lack of an official data source or API and limitations of emulators.
