this is my code:

    Dim jsonString As String
    Dim returnValue As Boolean
    
    Try
        API.Path = "/xxxx/xxxx"
        Libraries.APIConnection.Initialize("Job", Me)
        Libraries.APIConnection.PostMultipart(API.URL & API.Path, CreateMap("something":EditText1.Text, "something":EditText2.Text, _
             "someversion":Application.VersionName),Null)
        Wait For (Libraries.APIConnection) JobDone (j As HttpJob)
    
        If j.Success Then
            Dim parser As JSONParser
            jsonString = j.GetString
            parser.Initialize(jsonString)
            Dim root As Map = parser.NextObject
            Dim message As String = root.Get("message")
            Dim status As Int = root.Get("status")
            
            Select Case status
                Case 0
                    'can't put the code here, i deleted it
                Case 400
                    MsgboxAsync(message, "Error")
                    Wait For Msgbox_Result
                    returnValue = False
                Case 422
                    MsgboxAsync(message, "Error")
                    Wait For Msgbox_Result
                    returnValue = False
                    
                Case Else
                    MsgboxAsync(message, "Error")
                    Wait For Msgbox_Result
                    returnValue = False
            End Select
        Else
            MsgboxAsync(LastException,"")
            Wait For Msgbox_Result
            Log(LastException)
        End If
    Catch
        'Log(LastException)
        MsgboxAsync(LastException, "Error")
        Wait For Msgbox_Result
    End Try
    Return returnValue

I can't give more because this is a live and running app. Already published in playstore.

No other error except the error i posted above.

A last chance to provide more informations.

What is the Device you are using?
Where can we found the Documentation of this Device/this Api? URL
Where can we download a example project the Devicemanufacturer provides? Eclipse or Android Studio java Example.

I am using Mobile Payment Terminal, see attached picture.

I don't have a sample app or project for this from the manufacturer.
My app is running ok and no error in android phone, but not ok in this device.

Thank you @DonManfred for helping me, hope this will give you more info. Sorry for my bad english, I am not really good in english.
