## Overview

The tree contains two Android app modules: the root BookMarket app and a separate nested TableLayoutProject app. The available source excerpts contain no app code or README, so their behavior and inter-screen navigation cannot be confirmed. The graph therefore shows the activities and layouts present in the tree, with only tentative Android launch and layout associations; it does not infer a book-market workflow.

Main entry points: [`app/src/main/java/com/example/bookmarket/MainActivity.kt`](https://github.com/hyokim1025/kotlin-android/blob/master/app/src/main/java/com/example/bookmarket/MainActivity.kt) (Main activity), [`app/src/main/java/com/example/bookmarket/MenuActivity.kt`](https://github.com/hyokim1025/kotlin-android/blob/master/app/src/main/java/com/example/bookmarket/MenuActivity.kt) (Menu activity), [`TableLayoutProject/app/src/main/java/com/example/tablelayoutproject/MainActivity.kt`](https://github.com/hyokim1025/kotlin-android/blob/master/TableLayoutProject/app/src/main/java/com/example/tablelayoutproject/MainActivity.kt) (Main activity), [`app/src/main/res/layout/activity_main.xml`](https://github.com/hyokim1025/kotlin-android/blob/master/app/src/main/res/layout/activity_main.xml) (Main layout)
