Bring your apps into the modern era. Android UI design has evolved, and an Android developer needs to know about the most popular UI elements used today and when to use them. This course teaches developers how to incorporate side navigation drawers, create view holders, and implement custom layouts and views, and design a RecyclerView for mixed view types—such as a category header view and photo item view. Instructor Albert Lo grounds the lessons in a real-world project: a photography app that pulls photos from multiple sources, including Google Photos, and uses the new UI elements to display them in an interactive grid. Following these techniques will lead to more sophisticated and engaging user experiences for your Android apps.
