I use the same code and it is working for me. For sure i send only files which exists.

Based on the error the file your want to upload does not exists.
Upload a example project which shows the issue.

How did you create the file? the file should be name as coca_cola but where i suppose to create the file? i'm new in programmin
Dim fd As FileData
fd.Initialize
fd.Dir = File.DirAssets
fd.FileName = "coca_cola.png"
fd.KeyName = "coca_cola"

How did you create the file?

i copied the file to the right place.

It does NOT CREATE anything. The methods does Upload AN ALREADY EXISTENT Image/file.
If you do not have a coca_cola.jpg then create one. Or use the name from an existing file....

i'm new in programmin

then i guess you should start with the beginners guide... See https://www.b4x.com/b4a.html for the download

I know it do not create anything , it should be programmer create the file and i understand the code but my problem is where should i create the file? in phone folder or multipartpost folder? can u give the exact location of coca_cola file should be?

 

[DonManfred]

Files folder in your project.

DO NOT post your answer INSIDE the quote... The quote is what you want to comment.

i copied the file to the right place.

put your answer AFTER the quote. NOT inside

See this image....

 

[Erel]

Based on the error message you have set the file name to snap1.png not coca_cola.jpg.

 

[yes]

Based on the error message you have set the file name to snap1.png not coca_cola.jpg.

Thank you Erel. i did create the file as the code needed and i wrote the name exactly as the code. however it still not working and i noticed that my file in asset folder was not installed to the device instead it got deleted during execution, any advice to solve this?

the File to Upload must exsist! Test it with File.Exist....

Upload like this:

dim hc as okhttpclient
hc.InitializeAcceptAll("hc")  
  
Dim files As List
Dim fd As FileData
Dim NV As Map

    files.Initialize
    fd.Initialize
    NV.Initialize
  
    fd.Dir = 'the Phat, e.g. file.dirassets
    fd.FileName = 'the Filename
    fd.KeyName = "filename"
    fd.ContentType = "application/octet-stream"  'change to your FileType
    files.Add(fd)
  
    Dim req As OkHttpRequest
    req = MultipartPost.CreatePostRequest(url_GMA_Up, NV, files)
    hc.Execute(req, 1)

 

[DonManfred]

Test it with File.Exist

Does not help with files from the Files folder

 

[mw71]

Does not help with files from the Files folder

You mean Files Folder (in Projekt) that will saved in File.DirAssets?

 

[DonManfred]

You mean Files Folder (in Projekt) that will saved in File.DirAssets?

yes

a little bit OT (update),

I see that I use the following code to select one of the files (user can copy them to edit)

    If File.Exits..... = True
        Log("Liste Extern")
    Else If File.Exists(File.DirAssets,"liste.txt") = True Then 
        Log("Liste Intern")
        Liste2 = File.readlist(File.DirAssets,"liste.txt")
    end if

it works at me with File only at DirAssets.
