First, feasibility and customer needs are analyzed and requirement document is defined based on practical problems met in work. Then, both brief and detailed designs are finished with considering of the requirements, during which properties of DotProject are considered to simplify development and enhance system functions. Last, the development and debugging of Investment Warning Platform on Android is fulfilled based on detailed design, and DotProject is used to manage each phase of development process. At the end, this paper reviews the characteristics of development on Android, and summarizes the problems and resolutions. It also points out possible problems in later optimization and comes up with related resolutions.
