Android Question how to post a file to a server not in a browser

[MbedAndroid]

i'm trying to post data to a server. This is possible (and working) by point array of data. A very long string is the result
Also the server api accepts a file, much easier.

this works when posting it in browser

/trips.json?trip%5Bname%5D=test&trip%5Bdescription%5D=test&trip%5Bbad_elevations%5D=false&file=C%3A%5Cfakepath%5CAll_in_one_APP.gpx

using the same code, but the path is replaced by android path pointing to the same file.
In that case the server gives a error.
How should this work without a browser. Somehow the file should be collected and send to the server, which task is the browser i suppose.
Used Job.poststring to archieve this

I tried already to use job.postfile and job.postmultipart both giving a EOF

Anyone a idea?

postmultipart should work. please show exactly how you coded it.
the code snippet you show is a GET, not a POST. that would throw an error in the case of a "very long string". but the string you show isn't long. some details are missing.
you say, "the server gives an error". is it the same EOF error you report further down? or a different error? what error exactly? you're leaving out too much information. sorry.

the api documentation tells me to put some details in urlencoded format. That's the line i posted already. And it's a post not a get for sure.
With a array of points it works.
Trying to post a file in this way

        Job2.PostFile("https://ridewithgps.com/trips.json?email=[somemail]&password=[somepassword]&"&filestring,File.DirRootExternal &  TrainingdirectoryString,gpxfilename)

the servers throws

ResponseError. Reason: , Response: {"error":"There was a problem with your request."}

filestring is the urlencoded part

 Private filestring As String=$"trip%5Bname%5D=ALL-in-ONE+APP&trip%5Bdescription%5D=Trip+Ride&trip%5Bbad_elevations%5D=false&file=C%3A%5Cfakepath%5CAll_in_one_APP.gpx"$

i think you should look closely at the documentation.

You can use PostMultiPart with map too!

the documentation is very limited. I wonder i should urlencode the file too. Can give a it a try

did some experiments with postman agent. Turns out that you dont need any file parameters in the url string. Tried once more posting multipart with setup i found here:https://www.b4x.com/android/forum/threads/okhttp-replaces-the-http-library.54723/#content
working! Passed null for the map.
Thanks for the help!
