Android Question Web Service Tutorial

[Cüneyt Gargin]

Can someone a step by step guide to teach how to call a webservice methods,
for example, http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheit can be a good example to begin with.

In this way, I think we can communicate with any system, i.e. Sqlserver, oracle etc.

Please show me the place where i should look if there is already a tutorial.

Cheers,

Cuneyt

If you want to connect to a remote database server then you should use Remote Database Connector.

Http requests are handled with: HttpUtils2 - Web services are now even simpler

It is easier to work with non-SOAP requests:

Sub Activity_Create(FirstTime As Boolean)
   Dim job As HttpJob
   job.Initialize("j1", Me)
   job.PostString("http://www.w3schools.com/webservices/tempconvert.asmx/CelsiusToFahrenheit", _
     "Celsius=30")
End Sub

Sub JobDone(job As HttpJob)
   If job.Success Then
     Log(job.GetString)
   End If
   job.Release
End Sub

You will need to parse the XML result.

ok. thanks. although writing a parser might be tiresome. for a scalar value, it is ok but what if a webmethod returns a dataset ?

 

[DonManfred]

It´s no problem if the dataset is returned as JSON or XML

 

[Cüneyt Gargin]

Can you please show me an example, if dataset returned is xml.
