Still an issue with SSL

SteveBee · Jun 16, 2011

Having got my web service client to work on a simple WS, I turned to SSL
I am now trying to connect to "https://sendem.com/ASP/Smart_Dev.asmx" - and I got the error that referred to in a tutorial.

So I installed hc.InitializeAcceptAll("hc") in HttpUtilsService, but now I get a different error:
"java.net.UnknownHostException: sendem.com"

Clearly Sendem.com DOES exist....
Grateful for any insights..

I've just tried the following code and it works correctly:

B4X:

Sub Process_Globals
    Dim hc As HttpClient
End Sub
Sub Globals
    
End Sub

Sub Activity_Create(FirstTime As Boolean)
    If FirstTime Then
        hc.InitializeAcceptAll("hc")
    End If
    Dim req As HttpRequest
    req.InitializeGet("https://sendem.com/ASP/Smart_Dev.asmx")
    hc.Execute(req, 1)
End Sub
Sub hc_ResponseSuccess (Response As HttpResponse, TaskId As Int)
    Log("Success: " & Response.GetString("UTF8"))
    Response.Release
End Sub

Sub hc_ResponseError (Response As HttpResponse, Reason As String, StatusCode As Int, TaskId As Int)
    Log("Error: " & Reason & " " & StatusCode)
    If Response <> Null Then
        Log(Response.GetString("UTF8"))
        Response.Release
    End If
End Sub

java.net.UnknownHostException means that it failed to resolve the host name. Usually because it failed to connect to the dns server.

B4X:

Tx for the sample Erel... I made a new app, put your code in, linked in HTTP - and I still get the same error.

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
Error: java.net.UnknownHostException: sendem.com -1

But I can access the Web Service from FireFox without problem.

So there's something in this whole Androidian infrastructure that isn't functioning properly... hmm - where to start looking?

Are you testing it with a real device or with an emulator?

But I can access the Web Service from FireFox without problem.

Mobile Firefox?

Ok, got it.
It's not me <g> and it's not B4a.

It's an Emulator issue:
Android java.net.UnknownHostException: Host is unresolved
"remove, then re-create your AVD (virtual device/emulator) in Eclipse. It worked for me--first time."

In fact, all I had to do was terminate then re-start.

Thanks for the info, Erel - since my code was ok, it sent me looking elsewhere
