GPS Jobs

Perdí por completo el código fuente de mi aplicación Android y solo conservo el APK instalado en algunos dispositivos. Necesito recuperar un proyecto íntegro en Android Studio a partir de ese binario, con todo el código legible, los recursos ordenados y la posibilidad de compilarlo sin errores. La app hace un uso intensivo del teléfono (gestión de llamadas y sensores) y precisa acceso al GPS para su funcionamiento principal, por lo que el proyecto resultante debe conservar esas llamadas a la API de Android tal como funcionan hoy. El trabajo consiste en: • Descompilar el APK con herramientas como JADX, apktool o equivalentes. • Reconstruir la estructura del proyecto (módulos, Gradle, recursos, firmas). • Limp...

I need someone physically present in Eritrea to confirm whether a provided address is accurate. During the visit, use a GPS-enabled camera (smartphone is fine) to capture 10-15 clear photos of the exterior, focusing on the building signage and the immediate surrounding area so that its context is unmistakable. When you are on location, take a Google Maps screenshot that shows your live position at the site. Make sure the timestamp and coordinates or map pin are visible. Deliverables • 10-15 geo-tagged photos of the building’s exterior, signage, and surroundings • One Google Maps screenshot taken on-site I will verify the metadata and map pin to confirm authenticity before releasing payment. Feel free to ask any logistical questions ahead of the visit so the trip ...

I need a focused Android mobile application that reliably captures and stores device location data. The core scope is limited to two key capabilities: • Real-time location tracking that updates smoothly in the foreground and, where possible, in background mode without draining the battery. • A searchable, timestamped location history that is saved locally and can be exported in a common format (CSV or JSON). I am not requesting geofencing at this stage, but the code structure should make it easy to bolt that on later. Feel free to use Google Maps SDK, Fused Location Provider, Room, or any comparable libraries you are comfortable with; just keep the dependencies mainstream so future maintenance is simple. Acceptance criteria – The APK installs on Android 10+ without...

I am looking for an experienced Android developer to build a GPS plotter and tracker application for marine/boating use in the Seychelles (Indian Ocean). The app will be installed and used primarily on a Samsung Galaxy S25 Ultra and must work fully OFFLINE at sea, where there is no mobile data coverage. KEY FEATURES REQUIRED 1. Live GPS position plotting on a map of Seychelles waters (Mahé, Praslin, La Digue and surrounding banks/reefs), with lat/long display in degrees-minutes format. 2. Offline maps/charts — the app must cache or bundle map tiles (e.g. OpenStreetMap / OpenSeaMap or similar) so it works with zero internet connection. 3. Waypoint management — create, name, edit, delete and categorise waypoints (e.g. fishing spots, reefs, hazards), with icons and colour ...

Our pipe-laying project is moving into a sensitive corridor and an environmental survey focused on soil and water quality is required before trenching begins. I need complete baseline data that can satisfy permitting authorities and give our construction team clear guidance on how to handle any contaminants or naturally occurring constraints. The scope covers: • Designing a sampling strategy that meets ASTM and local EPA guidelines for both surface and groundwater, as well as representative soil horizons along the right-of-way. • Collecting field samples with calibrated probes (pH, EC, turbidity) and GPS-referenced locations so the findings tie directly into our existing GIS alignment files. • Coordinating certified laboratory analysis for full chemical composition&mdas...

I need a clean, reliable mobile app that lets users open their phone, tap once, and instantly see the nearest Masjid on a map. The build has to ship for both iOS and Android from the same code-base, so please choose a framework you are comfortable with—Flutter, React Native or similar—provided the final binaries run smoothly on the App Store and Google Play. Primary goal • Accurate GPS-powered discovery of nearby Masjids, displayed with distance, basic details and directions. Project flow 1. Kick-off call to confirm tech stack, map provider (Google Maps, Mapbox, Apple Maps, etc.) and minimal UI wireframes. 2. Weekly test builds delivered through TestFlight and Google’s Internal Testing track. 3. Final submission includes full source code, build instructions...
