If you plan to share only standard Java code, you can distribute them packaged as Java Archive Resources (. Also, if your code base begins to take longer times to compile and/or run, creating a library also enables you to iterate faster by working on a smaller component. You can share existing activities, services, images, drawables, resource strings, and layout files that enable other people to leverage your work such as those documented in the must have libraries guide.
