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.

Topics include:
* Creating a custom layout with XML
* Setting up onclick handlers
* Making API calls
* Creating custom views
* Implementing ViewHolder objects
* Signing certificates
* Adding a checkbox
