I use this function without problems in B4A and B4J .. but it generates an error in B4I (on Wait For)
B4X:
Public Sub ReadSingleResult(Query As String,Field As String) As ResumableSub
    Dim j As HttpJob
    Dim Result As String = ""
      
    j.Initialize("", Me)
    j.Download($"${url}query.php?query=${Query}&Field=${Field}"$)
    Wait For (j) JobDone(j As HttpJob)  <<<<------- ERROR

    'Log(j.GetString)
    If j.Success  Then
          Result=J.GetString
    End If
    Return Result
End Sub
ResumableSub said:

I have replaced the Spaces with% 20 (replace (" ", "%20), Now the error has changed slightly

Actually I always did so without problems (with B4A and B4J), I did not even know about Download2.
But would I solve it?

Download2 encodes the url parameters. If that is the problem here then it will solve it.
The error also persists with Download2.

I have deselected the iHttpUtils2 library and inserted the HttpJob sources.

I followed the error ... and if I run the program step by step with the debug .. the error does not occur ... if instead I run it in DEBUG mode (but not step by step) or in RELEASE I get an error.

As if it raised the event when the data are not there yet. Maybe I should take a break (Sleep o my dear DoEvent)

I solved by inserting a pause in the Sub Complete of the HttpJob class of the iHttpUtil2 library.
The pause can not be accomplished with the Sleep because it goes up one level and generates other errors, so I have worked to stop the flow of the program

Unfortunately I can not reveal how I made this break .... just know that it works or almost. Sometimes it still generates an error in debug mode.

B4X:
Public Sub Complete (res1 As HttpResponse)
    Response = res1
    #IF B4I AND DEBUG
        log("PAUSE 300")
       ' .................
       ' .................
       ' .................
    #End If
    CallSub2(target, "JobDone", Me)
End Sub
I lost a whole day of work for this nonsense. :mad:

I keep having a lot of anomalous errors in DEBUG and it works correctly in RELEASE.

It is not stable.
