Android Question How to treat httpjob timeout?

Your HttpJob is named Job1, not simply j
Correct the Wait For statement and it will work

I want to detect a timeout with httpjob.

I'm doing this:

B4X:

Dim Job1 As HttpJob
Job1.Initialize(...)
Job1.Poststring(...)
Job1.GetRequest.Timeout =5000 ' 5 seconds
Wait For (j) JobDone(j As HttpJob)
If j.Success Then
Log("succes")
Else
Log("failed")
End If

When I start my app without internet connection, I thought the "failed" message would be shown after 5 seconds. But nothing happens. It seems that Android is trying to do the PostString and "hangs" on that line. What am I doing wrong?

ResponseError. Reason: java.net.UnknownHostException: Host desconocido (xxxxxxxxxx), Response:

    Dim j As HttpJob
    Try   
        j.Initialize("", Me)
        j.Download("https://www.google.com")
        j.GetRequest.Timeout = 5000 ' 5 seconds
        Wait For (j) JobDone(j As HttpJob)
        If j.Success Then
            xui.MsgboxAsync(j.GetString, "OK")
        Else
            xui.MsgboxAsync("Error connecting", j.Response.StatusCode) 'error code
        End If
    Catch
        Log(LastException) 'Error general
    End Try
    j.Release

• The timeout parameter is ignored since it takes OVER 5000ms for the error to be displayed
• JobDone is never fired, so j.success cannot be checked
• The Try/Catch does not fire

        If j.Success Then
            xui.MsgboxAsync(j.GetString, "OK")
        Else
            xui.MsgboxAsync("Error connecting", j.Response.StatusCode) 'error code
        End If

Using Wait For we can wait for the JobDone event in the same sub that started the download.
No longer is it needed to have a single sub that handles all requests results.

When there is no internet, all I get is this message in the log window:
ResponseError. Reason: java.net.UnknownHostException: Unable to resolve host "www.test.com": No address associated with hostname, Response:

(and yes, the Response: is empty at the end of the line)

• The timeout parameter is ignored since it takes OVER 5000ms for the error to be displayed
• JobDone is never fired, so j.success cannot be checked
• The Try/Catch does not fire

Hi,
as you may know, standard timeout is set to 30s. If you experience a never ending wait, could it be caused by a firewall/antivirus that block your outgoing message?

the timeout may vary and depends on the request timeout setting on the web server.

No no, that can't be true. If we specify there should be a timeout for our httpjob, the timeout should fire when we reach OUR timeout, not the server timeout.
