NotSupportedException using RemoteProviderSettingsUri

Hi Mark, 

This is awesome! However, I am having a problem. When I point my RemoteAdProviderStrategy at my XML file on my site, I get a NotSupportedException during MC.Phone.Ads.Strategy.RemoteAdProviderStrategy.ParseXml(String xml). The app crashes. I was surprised it didn't simply fall back to the Local file as expected. If I don't specify the RemoteProviderSettingsUri, it works fine. I'd be happy to provide the stack trace and/or URI to the file if you're interested. 

I can access the xml in a browser so I don't think it's accessibility but I'm sure I'm doing something wrong.

Thanks for this btw. It really is great and I hope to figure out how to leverage the remote strategy before my next shipping.

Hi Jonathan,

It is indeed suprising that it didn't fallback. But the fallback mechanisme is during the gathering of xml. It could very well be that there's a small problem in the XML. If you could either share the url and/or the xml that would be great.

 

Best,

Mark,

Here is the URL I am using:

http://mobile.digitalmason.net/jackoftoolspro/AdSettings.xml

Here is the context:

<Ads:AdControl.AdProviderStrategy>           
<Strategy:RemoteAdProviderStrategy xmlns:Strategy="clr-namespace:MC.Phone.Ads.Strategy;assembly=MC.Phone.Ads"
LocalProviderSettingsUri="Ads/AdSettings.xml"
RemoteProviderSettingsUri="http://mobile.digitalmason.net/jackoftoolspro/AdSettings.xml" />
</Ads:AdControl.AdProviderStrategy>

When I remove the RemoteProviderSettingsUri, things work as expected using the XML in the XAP.

Thanks

Hi Jonathan,

 

I'm not completely sure, but my guess is that you're using Google Sites, or something similar. The direct response of that url is html instead of xml

From there in the browser there are a couple of redirects which in the end results in a url like: https://721799946776365234-a-digitalmason-net-s-sites.googlegroups.com/a/digitalmason.net/mobile/jackoftoolspro/AdSettings.xml?attachauth=*REMOVEDTHEVALUEFORSECURITYPURPOSE*&attredirects=0

I removed a small part of it. Maybe this is not the best place to host the file. I did a prove of concept with Dropbox which does work.

Hope this helps.

Best,

Mark,

Yes, you're right. It is Google sites. Now that you point it out, I noticed something weird with that one time but I guess the browser normally hides that and downloads the content. Sorry to waste your time on that and thank you for figuring it out.

I will find somewhere else to put the file or try dropbox.

Again, this is a really awesome library. I can't thank you enough.

On a related note (I think) I am getting the same error (stack trace below) hosting the remote AdSettings.xml on Dropbox.  I thought at first that I had the Xml wrong, as I had used a version of the Xml with a load of namespaces in it, but after changing that to the plainer version I am still getting a load of errors being returned.

I am wondering if Dropbox is returning an error as an Html page in some instances, the app is not that heavily used (unfortunately !) so I don't believe that it is overloading dropbox.

Here is the stacktrace in case it helps:

Hi Rupert,

 

Could you share the url to dropbox you're using? Did you place it in the public folder like I said in our previous discussion?

Hi Mark,

The dropbox link is http://dl.dropbox.com/u/309185/AdSettings.LI.xml - when I test it from a version deployed to a phone it seems to be OK, and also the version from the Marketplace appears OK, but it would appear that sometimes something is going wrong!

Here is the Xaml from the user control I have written to shown the Ads:

        <Ads:AdControl.AdProviderStrategy>
            <Strategy:RemoteAdProviderStrategy xmlns:Strategy="clr-namespace:MC.Phone.Ads.Strategy;assembly=MC.Phone.Ads"
                                            LocalProviderSettingsUri="Ads/AdSettings.xml"
                                            RemoteProviderSettingsUri="http://dl.dropbox.com/u/309185/AdSettings.LI.xml" />
        </Ads:AdControl.AdProviderStrategy>
Thanks,
Rupert.

Hmm, the url looks okay to me. But if it's difficult to reproduce I would not recommend using Dropbox. Better use something different instead.

Hi Mark,

As you say it is difficult to track down what the error actually is - I have not been able to reproduce it.

Would the crash above take out the application as well, i.e. would the control cause the application to exit with an error?

Thanks,

Rupert.
