An open-source Android demo app showcasing complex UI animations implemented both with MotionLayout and with plain Kotlin animation fundamentals. It serves as a companion to tutorial articles comparing the two approaches.

Use cases

• learn how to build complex multi-step animations on Android
• compare MotionLayout vs ValueAnimator-based animation implementations
• see how to animate RecyclerView item expand/collapse
• implement toolbar scroll animations with CoordinatorLayout Behavior
• find reference code for filter UI animations in Kotlin

When to choose

• you are an Android developer learning advanced UI animation techniques
• you want side-by-side examples of MotionLayout and programmatic animations
• you need reference code for complex expand/collapse or scroll-driven animations

When to avoid

• you need a production-ready animation library to drop into your app
• you are not developing for Android
• you need actively maintained code with a license for commercial reuse
