Using Windev MOBILE to create a Skeleton Framework for GPS Tracking on Android

We are seeking an experienced PC Soft WinDev Mobile (SAAS 2026)

developer to produce a fully working example project that will act as a

reusable code base for integration into our existing WinDev Mobile

application.

IMPORTANT:

You must have current, hands-on experience specifically with

WinDev Mobile (Android & iOS). The mobile platform differs significantly

from the desktop version of WinDev. Previous applicants have not had

relevant mobile experience.

Platform:

WinDev Mobile SAAS 2026

OBJECTIVE

Develop a working GPS tracking module for a walking/driving application

that:

• Runs on Android phones and tablets
• Runs on iOS phones and tablets
• Logs accurate GPS location data
• Works reliably in the background
• Operates offline and syncs when signal returns
• Provides a clean, welldocumented code base suitable for integration

This project is to deliver a standalone Skeleton/demonstration project that we

can then merge into our main application.

CORE FUNCTIONAL REQUIREMENTS

• GPS Tracking

The application must:

• Capture a full and accurate GPS location
• Log position every:
• (X) meters OR
• (X) minutes (whichever occurs first – configurable)

Each log must include:

• Latitude
• Longitude
• Timestamp
• Accuracy -Speed (if available)
• Bearing (if available)
• Local Storage
• Store all GPS data locally on the device
• Display the recorded route visually on a map
• Must function fully offline
• When mobile data is restored:
• Automatically send unsynced data to remote API
• API Integration
• Send GPS data via HTTPS POST to a configurable API endpoint
• Include secure headers/token support
• Implement retry mechanism for failed transmissions
• Prevent duplicate submissions
• This can just be a PHP post, we currently have an api we send to.
• Background Operation (CRITICAL REQUIREMENT)

The application must continue logging location under the following

conditions:

• Screen turned off
• Phone asleep
• App not in foreground
• User switches to another app
• App removed from foreground
• App manually closed

Background Behavior Requirements:

• No repeated notification banners every 30 seconds
• Only one persistent background notification (where required by OS)
• Must comply with Android and iOS background service requirements
• Must follow Apple background location service guidelines

This is a key part of the project and must be demonstrated clearly.

• Push Notifications - Currently we use firebase

The application must:

• Receive push notifications
• Support commands such as:
• Query device location
• Start logging
• Stop logging

ADDITIONAL FEATURES (SEPARATE PAGE/SECTION) - Not Essential but can be discussed

View Current Walk - Display current active route on a map - Show

distance travelled - Show elapsed time

View Recorded GPS Points - List stored points - Display route replay

Geofencing - Trigger event when: - Entering a defined geobox - Exiting a

defined geobox

DEBUG AND TESTING REQUIREMENTS

• Include debug screen showing:
• Live GPS updates
• Logging status
• API send status
• Offline queue count
• Provide clear testing instructions for Android and iOS
• Demonstrate background logging clearly

DELIVERABLES

• Fully working WinDev Mobile project (SAAS 2026 compatible)
• Clear code structure suitable for integration

Inline code comments explaining:

• Background services
• GPS handling
• Local storage
• Sync logic

Integration guide explaining:

• Required permissions
• Required iOS and Android configuration
• Project settings used
• API integration documentation

KEY REQUIREMENTS FOR APPLICANT

• Demonstrable experience with WinDev Mobile (not desktop WinDev)
• Experience with:
• Background services (Android and iOS)
• Mobile GPS handling
• Push notifications
• Offline data sync
• Ability to explain architectural decisions clearly

Please provide:

• Examples of WinDev Mobile projects
• Confirmation of experience with background location tracking
• Estimated cost
• Estimated timeline
• Clarification of any assumptions

PURPOSE OF THIS PROJECT

The primary goal is to produce a clean, well-documented, transferable

code base that we can integrate into our main walking/driving

application.

Clarity and maintainability are as important as functionality.

Contract duration of less than 1 month. with 30 hours per week.
