Does this service work with Xamarin for iOS now?

I was reading that for the past few years, users are not able to use App42 service because it does not support ipv6. Has this been resolved?

Unable add item to catalogue from webUI and source code

Mon, 02 Jul 2018 08:55:13 +0000

Can anyone tell me what is happening here? Unable add item to catalogue from webUI and source code.

Originally this service can function normally, but cannot carry on catalogueService.AddItem() in the last few days;

In addition, I use the App42 Management Console WEB UI for the add item operation, also can not normal new items !

If anyone can help me, thank you.

Catalogue catalogue = catalogueService.GetItemById(catalogueName, categoryName, sku);

if (blnAddProduct)

{

try

{

ItemData itemData = new ItemData();

itemData.SetItemId(sku);

itemData.SetName(sku);

itemData.SetPrice(Convert.ToDouble(price));

itemData.SetDescription("ModifyTime:" + DateTime.Now.ToString("yyyy/MM/dd HH:mm"));

itemData.SetImage(defaultImagePath);

Catalogue catalogue = catalogueService.AddItem(catalogueName, categoryName, itemData);

blnResult = catalogue.IsResponseSuccess();

}

catch (Exception e)

{

blnResult = false;

}

return blnResult;

App42/AppWarp Xamarin Missing IPv6 Support

Sat, 07 Jan 2017 16:45:45 +0000

Hello,

Apple is currently rejecting any apps using AppWarp and App42 for Xamarin because the SDK's do not support IPv6 networking. In this previous topic: http://forum.shephertz.com/?qa=9962/app42-appwarp-xamarin-no-ipv6-support it was said that an update would be released by December 31st 2016, but this has passed and I do not see any update anywhere. When is this update going to be released? This is a highly critical issue affecting all apps using the ShepHertz SDK's with Xamarin and if it could be fixed as soon as possible I would really appreciate it since it is holding up the release of my application completely.

I have tried emailing support and replying to multiple threads to get information about this but I am getting no responses anywhere. Please let me know what will be done to fix this and when the update will be available.

Thank You

Unhandled Exception in Airplane Mode

Sat, 26 Nov 2016 23:59:12 +0000

Hi,

I'm currently working on a Xamarin Forms app for iOS (published)/Android (published)/WinRT (soon to be published) using the App42 SDK for Xamarin2.0.

When testing on an iPhone 6S (iOS 10) or on a Moto X (Android M) in airplane mode, I get an unhandled exception from the App42 library that leads to a fatal crash of the app, which is definitely a show stopper. From the stacktrace, you can see that it is thrown from a thread that is owned by App42's library, over which I have no control. AFAIK, I can't catch and handle that exception.

A possible workaround would be to test for connectivity before calling any of App42's methods, but that exception (or a different one?) might still be thown if, for example, connectivity is lost between the test and the effective call... Best practice tells us to catch the exception on App42's side and pass it around through the error callback of the FindAllDocuments method.

Any idea how to remedy to the situation?

The Xamarin SDK I'm using (2.0) seems to be quite old (december 2015), is there a more recent/stable version around?

You'll find the details of the exception below.
