About this app

The Call Union article app is a platform for receiving real-time delivery requests and sharing work progress.
Based on prior consent between users, it supports efficient work performance by connecting the entire process from delivery request to completion in real time.

📍 Guide to foreground service and location permissions (Android 14 or higher)

The app uses the foreground location service through the FOREGROUND_SERVICE_LOCATION permission.

This permission is essential for the following reasons:

The task must start immediately upon receiving the request and must be performed without delay.

After accepting the task, interruption or pause is not allowed, and continuous location information transmission is required.

Since the delivery task must continue in real time even if the user uses another app or turns off the screen, the app must operate as a foreground service.

📌 Main functions for which this permission is used

Receiving real-time delivery requests
Automatically receives nearby requests based on the current location.

Sharing work status and location information
The status and location of accepted tasks are transmitted in real time.

Location-based event notifications
Provides automatic notifications based on conditions such as arrival or area entry/exit.

Continuously transmits location information even when the app is in the background
Delivery work continues even if the user switches the app or uses it for a while.
