Android Question Trapping Job.GetBitmapSample Error

[Mashiane]

Hi

Im running a job...

Dim bmp As Bitmap = Job.GetBitmapSample(100%x,100%y)

This returns a success operation, however the bitmap being read from the server does not exist. The above statement returns an error

java.lang.RuntimeException: Error loading bitmap.

How can I trap this or detect the non-existent image within the Job variable?

Use Try...Catch.

Are you checking that Job.Success is true?

Yes Erel I am, all my JobDone functions are structured the same..

Sub JobDone (Job As HttpJob)
    If Job.Success = True Then
        Select Job.JobName
        Case "registeruser"
            GetImageFromServer(Me, "http://www.xxxx.com/xxx/xxx.jpg", "getUserImage", "22")
        Case "getUserImage"
             Dim bmp As Bitmap = Job.GetBitmapSample(100%x,100%y)
             ' process the image
        End Select
   Else
       Select Job.JobName
           Case "getUserImage"
           'do something else
       End Select
   End If
End Sub

My module sub for getting images, this works

Sub GetImageFromServer(frm As Object, iLink As String, JobName As String, phpTag As String)
    Dim job As HttpJob
    job.Initialize(JobName, frm)
    job.Tag = phpTag
    job.Download(iLink)
End Sub

It never runs the Job.Success = False of the Else statement but just gives the error msg when the image does not exist. My GetImageFromServer works well for all existing images

This means that your server is misconfigured. It should return an error. As NJDude wrote you can use a Try / Catch block to catch the error.

Noted, the server is an ISP server and not mine. Can you please advise as to what they should perhaps fix, if you dont mind?

The server should return a status code of 404 if the requested URL is not available.
