Hi Team,

I am using .NET API of WURFL for Mobile detection. Device detection is not working fine some times. Mobile site shows desktop views. Issue is with body part that loads desktop view. Header & Footer shows Mobile.

I am using the WURFL version 1.5.1.0.

Global.asax.cs
protected override void Application_Start()
{
base.Application_Start();

BundleConfig.RegisterBundles(BundleTable.Bundles);

System.Threading.Tasks.TaskScheduler.UnobservedTaskException += TaskScheduler_UnobservedTaskException;

ModelBinders.Binders.Add(typeof(DateTime), new ShortLittleEndianDateBinder());
ModelBinders.Binders.Add(typeof(DateTime?), new ShortLittleEndianDateBinder());

LoadWurflData(Context);

DisplayModeProvider.Instance.Modes.Insert(0, new DefaultDisplayMode("Mobile")
{
ContextCondition = (context =>
{
var manager = (context.Cache[WurflManagerCacheKey] as IWURFLManager);

if (manager == null)
{
var server = Context.Server;
var appSettings = WebConfigurationManager.AppSettings;
var wurflDataFile = appSettings["WurflDataFilePath"];
var wurflPatchFile = appSettings["WurflPatchFilePath"];
var configurer = new InMemoryConfigurer()
.MainFile(wurflDataFile)
.PatchFile(wurflPatchFile);
manager = WURFLManagerBuilder.Build(configurer);
}

var cabablities = manager.GetDeviceForRequest(context.Request.UserAgent);
return cabablities.GetCapability("is_wireless_device") == "true";
//return cabablities.GetCapability("mobile_browser").Contains("Opera");
//return cabablities.UserAgent.Contains("Opera");
})
});
}

public static void LoadWurflData(HttpContext context)
{
var server = context.Server;
var appSettings = WebConfigurationManager.AppSettings;
var wurflDataFile = appSettings["WurflDataFilePath"];
var wurflPatchFile = appSettings["WurflPatchFilePath"];
var configurer = new InMemoryConfigurer()
.MainFile(wurflDataFile)
.PatchFile(wurflPatchFile);
var manager = WURFLManagerBuilder.Build(configurer);
context.Cache[WurflManagerCacheKey] = manager;
}

Layout.Mobile.cshtml Structure:

<div id="page" class="c">

Html.RenderPartial("_Error.Mobile", null);
Html.RenderPartial("_Session.Mobile");

Did you encounter this issue anytime? If so, please suggest.

Thanks,
Sandeep

Sandeep,

If I understand correctly, the `Layout.Mobile.cshtml` is being correctly displayed but your mobile views are not being correctly rendered?

Thank you,

Elliot

Yes Elliot, you are absolutely correct.

Layout.Mobile.cshtml(Header & Footer) renders Mobile View but the body part renders desktop view.
I hope Luca Passani has bcc 'ed to you in the mail. I mentioned there with clear screenshots and code as well. Please check.

In the site i am unable to attach the doc's.

Thank you,
Sandeep

Sandeep,

I did see the screenshots that were attached. I might recommend setting to try and debug this issue. From what I can see, WURFL is properly detecting the mobile device since your Layout.Mobile.cshtml file is being rendered for these devices. This could be an issue with the naming of the views with the body sections.

Elliot

Elliot,

I added the code in the Application_Start Event of Global.asax. I hope this is the correct way in attaching the code.

protected override void Application_Start()
{
base.Application_Start();

BundleConfig.RegisterBundles(BundleTable.Bundles);

System.Threading.Tasks.TaskScheduler.UnobservedTaskException += TaskScheduler_UnobservedTaskException;

ModelBinders.Binders.Add(typeof(DateTime), new ShortLittleEndianDateBinder());
ModelBinders.Binders.Add(typeof(DateTime?), new ShortLittleEndianDateBinder());

LoadWurflData(Context);

DisplayModeProvider.Instance.RequireConsistentDisplayMode = true;

DisplayModeProvider.Instance.Modes.Insert(0, new DefaultDisplayMode("Mobile")
{
ContextCondition = (context =>
{
var manager = (context.Cache[WurflManagerCacheKey] as IWURFLManager);

if (manager == null)
{
var server = Context.Server;
var appSettings = WebConfigurationManager.AppSettings;
var wurflDataFile = appSettings["WurflDataFilePath"];
var wurflPatchFile = appSettings["WurflPatchFilePath"];
var configurer = new InMemoryConfigurer()
.MainFile(wurflDataFile)
.PatchFile(wurflPatchFile);
manager = WURFLManagerBuilder.Build(configurer);
}

var cabablities = manager.GetDeviceForRequest(context.Request.UserAgent);
return cabablities.GetCapability("is_wireless_device") == "true";
//return cabablities.GetCapability("mobile_browser").Contains("Opera");
//return cabablities.UserAgent.Contains("Opera");
})
});
}

Let me know the speciality of adding this piece of code and how it can be helpful?

In Normal debugging without adding the piece of code given. I got below outputs.

It displays for me 3 display Modes. 1. Mobile 2. Mobile 3. ""(i.e., desktop)

It gives WURFL Info with version property as "((((WURFL.WURFLManager)(manager))._service._deviceRepository).WurflInfo).WurflVersion"
for "WURFL API 1.5.1 release, db.scientiamobile.com - 2014-02-07 18:02:36" and some other stuff.

Note: This Issue persists in the production after 3 to 4 hours. Its not persisting every time.

Please suggest ..

Sandeep

Hello Sandeep.

As I can see from your code, WURFL query happens only once.
Are you able to verify if one HTTP request may lead to multiple WURFL queries?
.NET documentation here
http://msdn.microsoft.com/en-us/library ... 11%29.aspx
states that

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Can you verify that it is not a synchronization problem?

I have also noticed that some people are complaining about caching issues, still regarding this class.
I can't find any explicit reference in the code snippet that you pasted here that suggests to investigate in this direction, but please consider taking a look at that.

Thanks,
Fulvio
