Android app built with Firebase and Google Maps to help users report COVID-19 status, view nearby affected users, and let health workers log in, mark patient counts, and browse a basic forum.

• Location-gated launch that prompts for GPS and location permission before entering the app.
• User flow: phone verification → profile capture (name, age, blood group, medical info) → home dashboard with quick links to maps, emergency contacts, prevention info, and donation links.
• Map view (UserMapsActivity) showing nearby affected users via GeoFire + Google Maps with live marker updates.
• Worker flow: email/password login → worker home with patient marking and access to the forum.
• Forum: simple Firebase Realtime Database feed listing submitted cases/treatment experiences; workers can post via post_forum.
• Background services: locationupdate/Location_Services for location tracking hooks (permissions required).

• Android SDK 29 (minSdk 24), Android Gradle Plugin 3.6.3
• Firebase Auth, Realtime Database, Analytics
• Google Play Services: Maps, Location
• GeoFire for geo queries
• AndroidX + legacy support libs (appcompat/constraintlayout)

• Root Gradle settings in settings.gradle; app module at app/.
• Key activities under app/src/main/java/com/example/kash/:
  • MainActivity: splash, GPS/permission gate, routes to login_global.
  • login_global: entry selector for user vs worker.
  • login_user and user_verification: collect phone/profile data and persist to Firebase (Users, Unaffected).
  • home: user dashboard with navigation to maps, emergency contacts, prevention info, donations.
  • UserMapsActivity: Google Map + GeoFire markers for nearby affected users.
  • login_worker and worker_home: worker auth and home; stops location service, opens forum/patient marking/settings.
  • forum + forumdb: reads Realtime DB FORUM entries and renders them.
  • Other screens: patient_num, mark_worker, post_forum, profile, settings, settings_worker, preventive_measure, emergency_contact, password_change, etc.

• Android Studio (3.6+ recommended) with Android SDK 29.
• A Firebase project with Realtime Database and Authentication enabled.
• A Google Maps API key (placed in app/src/main/res/values/google_maps_api.xml).

1. Clone the repo and open the root folder in Android Studio.
2. Firebase config: place your google-services.json under app/ (file is already referenced in the repo path).
3. Maps API key: update google_maps_api.xml for debug/release with your key.
4. Sync Gradle. If you see play-services/Firebase version clashes, align to a single BoM or bump the versions (the project mixes AndroidX and legacy support libs).

• From Android Studio: Run the app configuration on a device/emulator with Google Play Services.
• From CLI:
  • ./gradlew clean assembleDebug
  • Install the APK from app/build/outputs/apk/debug/ onto a device with Google Play Services.

• Location: ACCESS_FINE_LOCATION, ACCESS_BACKGROUND_LOCATION, FOREGROUND_SERVICE used by maps and tracking services.
• Network: ACCESS_NETWORK_STATE for connectivity checks.

• User profile writes to Firebase paths Users/{uid} and Unaffected/{uid}.
• Worker login uses Firebase Auth email/password; email is cached in shared preferences (ID).
• GeoFire reads/writes from Locations to place markers for affected users.
• Forum posts live under FORUM in Realtime Database; forumdb is the model for entries.

• Location permission is mandatory; the app exits if GPS is disabled.
• The code mixes AndroidX and old support libraries; consider migrating fully to AndroidX to avoid conflicts.
• Ensure proper database rules and authentication in Firebase before deploying.
