HTTP2UTILS errors and crashes

Rhonan · Oct 17, 2012

Hi all,

I guess I'm doing something wrong as the new http2utils routines are meant to be robust.. so i hope you can help.

I'm getting a lot of errors now that seem to be escaping my error handling and crashing my app. These are normally when there's a problem with the data connection. I've seen crashes when I've had a 500 error reported, when i've hit firewalls, or ECONNRESET, or when i apparently just can't connect. THe following is the logs from a bad connection. I hope you can help me error-trap these correctly so i won't crash the app. Currently I'm just error trapping using the success flag of the http function.

logs below..

thank you
Ronan

Can you post the JobDone code?

Please use [ code ] [ /code ] tags (without spaces) when posting code.

The important code is not here. How do you access the downloaded resources?

I recommend you to use Log keyword to log messages. It is much more convenient than showing toast messages.

Rhonan · Oct 23, 2012

"Main.http_message = Job.GetString"

Erel,

thanks for replying. The active code is the above line at the top of the file. All the subsequent subroutines are processing this global text string.

Is that what you were asking for?

Erel · Oct 23, 2012

You can only access the resource if Success is true.

Rhonan · Oct 23, 2012

I've noticed that I'm asking for the "job.getstring" before checking for job success. Could this be the problem?

See my answer above (we were "double" posting).

thanks... makes sense in hindsight. appreciate all the help!

I have this error :

B4X:

java.lang.RuntimeException: Error loading bitmap.
httpjob_getbitmap (B4A line: 118)
b = LoadBitmap(HttpUtils2Service.TempFolder, taskId)
java.lang.RuntimeException: Error loading bitmap.

This is my JobDone :

B4X:

Sub JobDone (Job As HttpJob)
    If Job.Success = True Then
      ImageView1.Bitmap = ImageJob(i).GetBitmap
   Else
      Bitmap1(i).InitializeSample(File.DirAssets,"transparent.png", SymbolWidth, SymbolHeight)
      ImageView1.Bitmap = Bitmap1(i)
   End If
   Job.Release
End Sub

Erel · Dec 23, 2012

Are you sure that you are downloading a valid image?

enrico · Dec 23, 2012

I've done this :

B4X:

'Initialize ImageJob Array 
For i = 0 To 29
     ImageJob(i).Initialize("ImageJob(" & i & ")", Me)  
End If

'Assign Links
ImageLink(0) = Main.imgDir & "image0.png"
ImageLink(1) = Main.imgDir & "image1.png"
ImageLink(2) = Main.imgDir & "image2.png"
ImageLink(3) = Main.imgDir & "image3.png"
ImageLink(4) = Main.imgDir & "image4.png"
ImageLink(5) = Main.imgDir & "image5.png"
.......

I want to put those images in a scrollview, so :

B4X:

Panel0 = ScrollView1.Panel
For i = 0 To 29
        Dim Panel1 As Panel
        Panel1.Initialize("")
        Panel1.RemoveView
        PanelHeight = 99dip
        Panel0.AddView(Panel1,0,PanelTop,ScrollView1.Width,PanelHeight)
        ImageView1.Initialize("ImageView1")
        ImageJob(i).Download(ImageLink(i))
        ImageView1.Gravity = Gravity.Fill
        Panel1.AddView(ImageView1,5dip,17dip,SymbolWidth,SymbolHeight)
        PanelTop=PanelTop+PanelHeight+1dip
Next
Panel0.Height=PanelTop

What I see from the log is that it seems that Jobdone always processes image4.png (???), it does it 5 times (always i = 4) and then stops with error :

httpjob_getbitmap (B4A line: 118)
b = LoadBitmap(HttpUtils2Service.TempFolder, taskId)
java.io.FileNotFoundException: /data/data/...packagename.../cache/5 (No such file or directory)

This error appears 5 times consecutively before program stops.

Erel · Dec 24, 2012

Can you post the full code?

enrico · Dec 24, 2012

Sorry but I gave it up and I'm doing it with WebView (and it works), so I've modified all the code.
For sure it was my fault to not understand correctly how httputils2 works.
Maybe I will try later to investigate it.
