I try to do a simple cross platform app that consumes secure resources onan arcgis online oragnization. I use Authentication Manager in my shared project to access secure ressources. The UWP app automatically prompts the user to provide login/password info. It's pretty straightforward. I thought it would act the same way on a Xamrin.Android app but id doesn't. Am I wrong? I try to do a cross platform project (Xamarin.Forms), but Android project doesn't act the same way. It doesn't prompt the user for login/password. Do I have to handle it by defining a challenge handler (so a custom UI) to let the user enter his login/password)? Why? Thanks in advance for any clarification on this. Will the upcoming toolkit make this easier? Is there any other things to consider when developping a cross platform app ? olivier

Hi, Is there a way to use OAuth 2.0 with Portal for ArcGIS 10.3. I know that the developpers documentation tells that it's not supported (https://developers.arcgis.com/authentication/arcgis-server-and-portal-for-arcgis/ ), but when I try to navigate to this url (http://myportal/arcgis/sharing/oauth2 ) on my portal I can access a web page and try to register an App. But trying to do that fails. On the other hand, on Portal 10.3, it's possible to register an App and to get an AppID and AppSecret. I've tried to use it with a proxy, in order to grant access to my app to anymous user, but it doesn't work. Any clarification and help is welcome. Thanks! olivier

Does ArcGIS Runtime SDK for Java (and others Runtime SDKs) support real time differential GPS (EGNOS and WAAS)? Does it depend on the GPS receiver? Does the SDK handle and apply the differential correction information (received through NMEA sentences)? Any details about real time diffrential GPS with ArcGIS Runtime SDK is welcome. If this is not supported in the SDK, is there an alternative approach (using third party SDK to handle real time differential correction)? olivier

Today you can get back your data from ArcGIS Online in several ways: -download link from feature service item -using ArcGIS for Desktop (ArcMap), you can also use your hosted feature service, then right clic on the layer in the ArcMap TOC and choose Export Data: you will be able to export the data to a local gdb. If you choose Edit > create a local copy for update: this will create a local geodatabase on your dekstop. In that case, data will be extrated according to the view extent. -using python Note that you can also consider that your data now live in the ArcGIS Online storage, and you can use it with the hosted feature service in ArcMap or from any other applications. Also, please note that according to the road ahead technical workshop during the UC 2014 last week, future updates of ArcGIS Online will offer new capabilities such as sync data between ArcGIS Online hosted services and multi users geodatabase. Stay tuned.

I've tried to build an AddIn (custom command that leverage the ArcGIS Server 10.1 capabilities) using API 3.0 but I have no choice but to use the Exentisibility Framework 2.4. Building the xap file is not a problem, but uploading the AddIn to the Viewer generates an error : "Object reference not set to an instance of an object." Is it because of the Extensibility dll version (2.4) or something else is wrong? Is there a workaround? If not do we have to wait for the next version of the Viewer? any release date? Thanks, olivier

Does ArcGIS Runtime allow to embed and use a local geometry service? If yes, how? The WPF API contains a LocalGeometryService class in the ESRI.ArcGIS.Client.Local Namespace, and a LocalGeometryServiceTask calss in the ESRI.ArcGIS.Client.Tasks Namespace (both in the ESRI.ArcGIS.Client.Local assembly) but no method to project data (no Project or ProjectAsync method). How to do that? How to handle a disconnected editing workflow using the Editor Widget without local geometry service or any other disconnected workflow that needs a geometry service? olivier
