Android Question maxJsonLength

[Carles Escudé]

I am trying to get a base64 coded image and getting it in a json string. Then I decode it and show in my app. That works until I try to get a bigger image where I get the following message:

Spanish:
System.InvalidOperationException: Error durante la serialización o deserialización mediante JavaScriptSerializer de JSON. La longitud de la cadena supera el valor establecido en la propiedad maxJsonLength.

English:
Exception information:
Exception type: InvalidOperationException
Exception message: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

The json string I am trying to get is less than 3000000 characters.

I was looking information about it and I found this:

http://stackoverflow.com/questions/1151987/can-i-set-an-unlimited-length-for-maxjsonlength-in-web-config

But the error persists.

I am using libraries HTTP (v1.36) and JSON (v1.10).

Thank you very much in advance

JavaScriptSerializer

Using httputils and jsonparser there is no JavaScript involved!?

I don't know... That's the error I get using B4A.

Dim job1 As HttpJob   
job1.PostString(Url, prms)

After that I get the error I write before.

 

[DonManfred]

Can yu post the code which parses the result?

 

[Carles Escudé]

Sub JobDone (Job As HttpJob)
    If Job.Success = True Then
        Select Job.JobName
            Case "Job2"
[...]

When I send the image, Job is not success, I get the error and the program brokes.
When I don't send the image it works ok.

Thanks for the interest.

When I send the image, Job is not success

What is the output of log(job.ErrorMessage) in this case?

 

[Carles Escudé]

"Internal Server Error"

 

[DonManfred]

So the problem seems to be on server side. Not in B4A

 

[Carles Escudé]

Yes. I know that. I start saying i was looking if the solution may be in some configuration in the web.config file.
I was asking if somebody know how to solve it.

I will try with the MSSQL library.

Thanks for all.

I finally did what I was looking for with that library:
