Overview This document outlines the development of a mobile application designed to track user location, time, and distance traveled. The application includes features to start and stop tracking, periodically store tracking data to a database via an API, and ensures data is collected at regular intervals when tracking is active.

Screens and there function Home Screen The Home screen in the application serves as the main interface for initiating and managing location tracking sessions. It provides functionalities to start and stop tracking, display the user's current location on a map, and track elapsed time and distance traveled during the session. Functions readData Description: Reads the user's token from AsyncStorage for authentication purposes. handleStartTracker Description: Initiates the tracking session by sending a POST request to the backend API to start tracking the user's location. handlePauseTracker Description: Pauses the tracking session by sending a POST request to the backend API to stop tracking the user's location temporarily. handleUpdateLocations Description: Updates the user's current location by sending a POST request to the backend API with updated latitude, longitude, and location ID. calculateDistance Description: Calculates the distance between two geographical coordinates using the Haversine formula. startForegroundLocationUpdates Description: Starts updating the user's location in the foreground at regular intervals using the device's geolocation service. stopForegroundLocationUpdates Description: Stops updating the user's location in the foreground and clears the interval set for location updates. startLocationTracking Description: Initiates location tracking by starting foreground location updates and setting up a timer to track elapsed time. stopLocationTracking Description: Stops location tracking by stopping foreground location updates, calculating distance traveled, and sending the final tracking data to the backend API. Timeline Screen Functions readData Description: Reads the user's token from AsyncStorage for authentication purposes. calculateTotalDistance Description: Calculates the total distance traveled based on the tracking sessions data. useEffect Description: Invokes the readData function on component mount to fetch tracking data. Activity Screen Functions toggleShow1 Description: Toggles the visibility of the dropdown menu for selecting the year. toggleShow2 Description: Toggles the visibility of the dropdown menu for selecting the month. toggleShow3 Description: Toggles the visibility of the dropdown menu for selecting the day. setDay Description: Sets the selected day for viewing activity data. setMonth Description: Sets the selected month for viewing activity data. setYear Description: Sets the selected year for viewing activity data. Profile Screen Functions getToken Description: Fetches the user's authentication token from AsyncStorage. toggleIsLogin Description: Toggles the user's login status. toggleUserLoginStatus Description: Toggles the user's login status and updates AsyncStorage accordingly.
