It's a simple master-detail application with interesting animation effects. This app provides examples of terrific animations which you can implement using only standard elements of Android Material Design. All screens were designed using ConstraintLayout and based on fragments.
List of cards contains CoordinatorLayout with CollapsingToolbarLayout. They manage curtain effect when user pulls image from the top. Locations of title, subtitle and fab are calculated by custom CoordinatorLayout.Behavior. OnOffsetChangedListener manages height of item and its image. It provides smoother animation than onDependentViewChanged method from AppBarLayout.ScrollingViewBehavior. A shared element transition is used to animate switching of fragments.
Data source was hardcoded but I added a delay using RxJava like in a real network based app. Also enter animation was added after "loading" a data. It is based on a ConstraintSet.
