How do I transfer a Route from PC to Mapfactor on Android?

Hi!
I have been trying the following:
I use Linux, I want to plan a route in qlandkarteGT (OSM map) and transfer the waypoints to my Android Phone using Mapfactory Navigator with OSM maps.

For this, I marked waypoints in qlandkarteGT, exported them to gpx, translated the gpx file to Mapfactory format using gpsbabel. So far so good.

Then I used a text editor to transfer the resulting points to favourites.xml, but when I move the file to the mapfactory directory, I can not find the points in "my locations".

Also when I edit the points to routing_points.xml I cannot find them when starting the navigator app.

I make really sure that the app is stopped before transferring the xml files to the smartphone.


Navigator is installed on the external SD card, there is a directory named "navigator" from which I took the xml files, transferred them to the linux PC to edit them and transferred them back. No effect.

Also I tried editing routing points in MapfactoryNavigator in the App, but these only show up in the App,  not in the xml files.


Where is my error ? Do I edit the wrong files or in the wrong location ?  The Android File explorer shows that I am using files in "/storage/extSdCard/navigator".

On the device memory, there is also a "navigator" directory, but it is empty.
