You may have to either learn to convert gpx to something App Inventor can use or modify your concept of how your app should work. ![]() Hope something here helps you continue your Project development. ![]() GPX format shows what the gpx file looks like. Regardless, in order to post the trak on a Map component, that information must be converted into a LineString or FeatureCollection. App Inventor can handle xml files, so it might be possible to work with the gpx as a xml. ![]() GPX, or GPS Exchange Format, is an XML schema designed as a common GPS data format.Provide an app to convert gpx files to a geojson and your users could download the ‘converted gpx’ from a googlespreadsheet or whatever.

There are two examples (one using Map, the other usin GoogleMaps API) that post a Marker or a series of LineStrings (a trak) on a map either using a timer or on demand.or using the LocationChanged block ( if I remember correctly). “maybe something completely else?” Here is how App Inventor users can provide traks in their app (not gpx format but they are traks)Īpp Inventor GPS Trak Basics.What you do depends on where your trak information resides and its source. Either do that with Blocks or outside of AI, convert the gpx to a json file (that AI can use)… You already have a basic framework that works but is slow for large gpx files. App Inventor cannot convert gpx tracks to a FeatureCollection using a native tool. ![]()
