OSMTracker for Android™ is a mobile app designed for OpenStreetMap mappers and outdoor adventurers. It lets you log a GPS track to document your journey. Its customizable buttons let you simply add POIs as track points directly inside your GPX track.

It also supports voice recording, picture taking, and note-taking. This is the perfect app to survey a place or a path whether you are hiking, cycling, or exploring new areas.

Here is a screenshot of the main screen with its default buttons. You can customize these buttons to your liking.

OSMTracker for Android™ official source code repository is https://github.com/labexp/osmtracker-android.

The PFandroid dashboard now supports realtime GPS anomaly updates via Socket.IO.

To exercise the integration locally:

1. Start the demo backend:

   cd server
   python -m venv .venv
   source .venv/bin/activate
   pip install -r requirements.txt
   python server.py

2. Build and install the Android app in debug mode. The debug build automatically points to http://10.0.2.2:5000.
3. Trigger an event from another terminal:

   curl -s http://localhost:5000/pixel/teste.png > /dev/null

Every call emits a novo_evento payload, incrementing the anomaly counter in GpsAntifragilFragment almost instantly. For production deployments, update the socket_url resource in app/build.gradle to the appropriate wss:// endpoint.
