App size optimization in Android Kotlin - UI Render Trace

Component - App size optimization

This UI component shows a simple Android app screen with a button to simulate app size optimization steps. It helps visualize how optimizing app size can improve app performance and user experience by reducing unnecessary resources.

Widget Tree

ConstraintLayout
├── TextView (Title)
└── Button (Optimize Size)

The root layout is a ConstraintLayout containing two children: a TextView at the top showing the title, and a Button below it that triggers the app size optimization process.
