booksource

booksource is a collection of Android source-code projects accompanying the second edition of the programming book The First Line of Code. The repository organizes examples by chapter so readers can study working implementations alongside the material. It starts with introductory projects such as Hello World and progresses into broader Android development concepts. Included examples demonstrate activities, lifecycle behavior, layouts, widgets, custom views, ListView, and RecyclerView. Other projects explore fragments, broadcasts, location services, Material Design, and a complete weather application. It serves as a practical reference for learners who want executable examples of concepts discussed throughout the book.
