[sophie]

Maybe this will help How to import, create and use gpx and kml track files using App Inventor Map Part II Use SAF extension to select kml/gpx files stored in your Documents folder

what about following the tutorial?

🛤️ How to import, create and use gpx and kml track files to App Inventor Map

How to import, create and use gpx and kml track files to App Inventor Map GPX / KML File Reader/Creator provides a way to import map route displays made with Garman GPS devices or Web pages that publish kml hiking routes (hiking tracks etc.). App Inventor uses a LineString to display a similar track. A gpx or kml file can be 'converted' to a set of location 'points' and loaded to a LineString and saved so it can be used for future use in the device's Documents folder. [testgpx] (gpx file f…

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

Well for this project i am searching for a solution to import .kml files that already exist in my Google Drive and not to make blocks with buttons to import .kml file as shown in the previous tutorials that you send me!

Download file and then import. I see no problem there.

App inventor does not have a native way to directly use kml files with OpenStreetMap tiles. Why not try this tutorial (already mentioned by Taifun) or use SAF? you can not merely copy kml/gpx files into the Documents folder and expect them to be usable with the the compiled app . Usable files must be created with the compiled app.

This is what is available at the moment. If you want to do this another way you might have to write your own extension to use your kml file. This is primarily because Google security restricts how an app can use files that the app itself did not create.

See KML - OpenStreetMap Wiki the section KML data into OSM.

Alright i will check it ! May i ask you if you know any other way to import shapefile data to my OSM in the app;

@sophie

know any other way to import shapefile data to my OSM

Perhaps Shp2osm - OpenStreetMap Wiki . However this would not be compatible with the Map component. You would have to use (if it would work at all) usingthe OSM api instead of Map to display the map.
