Android Question HttpJob Intermittent Crashes

[DawningTruth]

The following code works, but intermittently crashes. It is pretty much exactly what is described in the examples. So I am stumped.

Sub UrlFetch(getUrl As String, param() As String) As ResumableSub
    
    Log("==============================================")
    Log(">> UrlFetch")
    Log("==============================================")
    
    Dim job As HttpJob
    Dim urlContent As String
    
    job.Initialize("", Me)

    job.Download2(getUrl,param)
    Log("FINISHED: UrlFetch -> Start Download Job") 'Checking if request is executed
    Wait For (job) JobDone (job As HttpJob)
    Log("FINISHED: UrlFetch -> End Download Job") 'Checking if response is executed
    
    If job.Success Then
        Log(job.GetString)
        urlContent = job.GetString
    Else
        Log("Error: " & job.ErrorMessage)
    End If
    job.Release
    
    'CallSubDelayed(Me, "UrlFetch_Complete")
    
    Log("FINISHED: UrlFetch") 'Check if sub finished
    Return urlContent
    
End Sub

Here are the Logs:

Any assistance is greatly appreciated.

2. Where it fails...

Based on the logs above I presume it fails at the:

Wait For (job) JobDone (job As HttpJob)

As per the comment below:

job.Download2(getUrl,param)
Log("FINISHED: UrlFetch -> Start Download Job") 'Checking if request is executed[/COLOR][/COLOR]
Wait For (job) JobDone (job As HttpJob) '<==== FAILS HERE - Does not go to the next step
Log("FINISHED: UrlFetch -> End Download Job") 'Checking if response is executed

 

[Erel]

It fails in MyWebView_PageFinished sub.

 

[DawningTruth]

It fails in MyWebView_PageFinished sub.

Thx Erel .

I will investigate there.
