Abstract: A computer system includes memory and at least one processor. The memory stores a codebase, multiple reusable software modules, and computer-executable instructions. The codebase includes an application class extension, an activity class extension, a module base definition class, and a theme. The instructions include creating a software application using the application class extension and the theme from the codebase, registering at least one of the multiple reusable software modules to the software application, and configuring the software application to arrange navigation for each activity of each reusable software module registered to the software application, to present a same user experience throughout the software application. The instructions also include configuring the software application to automatically apply a same layout theme for each activity of each reusable software module registered to the software application, to present a same user experience throughout the software application.

Abstract: A system for authoring a software application includes an application codebase that has an application class extension, an activity class extension, a theme, and a module class. The application codebase is used to generate a software module to be incorporated into the software application. The software module extends the module class, the software application includes at least one activity, and the software application specifies the application class extension that is common to the software module. The software application specifies the theme, and the activity of the software application extends the activity class extension.
