Accessing secure ressources in a cross platform project (v100.0)

[OlivierROSSINI]

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 ?

I can't answer definitively, but that's how I implemented it in a Forms app (Android and iOS). I've never seen any default dialogs handling user credentials.

Hi,

There's no default authentication UI in our API for Xamarin, but it's something we'll consider for the toolkit. UWP has a built in UI as you discovered and we have added a prototype UI for WPF to the v100.0 Toolkit branch arcgis-toolkit-dotnet/src/Esri.ArcGISRuntime.Toolkit/WPF/UI/SignInForm at v100 · Esri/arcgis-toolkit... 

You'll find some v100 protocol-specific security samples for Forms in arcgis-runtime-samples-dotnet/src/Forms/Shared/Samples/Security at master · Esri/arcgis-runtime-samp... 

 Cheers
