## Overview

Dr. Sanjini is an Android healthcare app for managing personal health information and finding nearby care. Its documented workflow spans onboarding and health records, symptom analysis, local care discovery, and ongoing medication and appointment management. The tree identifies corresponding screens, ViewModels, repositories, API services, and Room database code, but the sampled source contains no runtime implementation; edges therefore reflect only README-documented behavior and omit uncertain internal wiring.

Main entry points: [`app/src/main/java/com/example/myapplication/map/MapFragment.kt`](https://github.com/gyeongrimnam/dr.sanjini/blob/main/app/src/main/java/com/example/myapplication/map/MapFragment.kt) (Nearby care map), [`app/src/main/java/com/example/myapplication/home/HomeActivity.kt`](https://github.com/gyeongrimnam/dr.sanjini/blob/main/app/src/main/java/com/example/myapplication/home/HomeActivity.kt) (Home navigation), [`app/src/main/java/com/example/myapplication/data/AppDatabase.kt`](https://github.com/gyeongrimnam/dr.sanjini/blob/main/app/src/main/java/com/example/myapplication/data/AppDatabase.kt) (Local health database), [`app/src/main/java/com/example/myapplication/api/service/HospitalService.kt`](https://github.com/gyeongrimnam/dr.sanjini/blob/main/app/src/main/java/com/example/myapplication/api/service/HospitalService.kt) (Hospital services)
