Hi there and welcome, I noticed that you are
coming from the madebyuppercut.com tutorial.
You might be interested in a new tool I created specially to make GPX files for Xcode and Android development environments.
This tool accepts a link to pre-made Google Directions and converts them to a GPX file. This file can be uploaded and used in sat-nav and GPS units.
This tool is built by a GPS amateur, please treat the output with scrutiny.
* You can also use shortened urls, e.g. https://goo.gl/maps/TFxlI
Are you developing mobile applications ?
I have a new tool designed to convert complex Google Maps direction routes into replayable GPS routes to use when developing location aware applications.
Works with Xcode, Eclipse, Android Studio and Visual Studio.
Take me there
I also have a tool for www.strava.com GPX export, go to mapstogpx.com/strava
