Hi team we are referring this simple map display sample: https://developers.arcgis.com/net/forms/sample-code/display-map/ We created a blank solution and added the following code: MainPage.xaml ==Start== <?xml version="1.0" encoding="utf-8" ?> <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:esri="clr-namespace:Esri.ArcGISRuntime.Xamarin.Forms;assembly=Esri.ArcGISRuntime.Xamarin.Forms" x:Class="LicenseIssue.MainPage"> <StackLayout> <Grid> <esri:MapView x:Name="GMyMapView"/> </Grid> </StackLayout> </ContentPage> MainPage.xaml ==End== MainPage.xaml.cs ==Start== using System; using System.Collections.Generic; using System.ComponentModel; using System.Linq; using System.Text; using System.Threading.Tasks; using Esri.ArcGISRuntime.Mapping; using Xamarin.Forms; namespace LicenseIssue { public partial class MainPage : ContentPage { public MainPage() { var a = new Esri.ArcGISRuntime.Xamarin.Forms.MapView(); //InitializeComponent(); InitializeComponent(); // Create the UI, setup the control references and execute initialization Initialize(); } private void Initialize() { // Create new Map with basemap Map myMap = new Map(BasemapStyle.ArcGISImageryStandard); // Assign the map to the MapView GMyMapView.Map = myMap; } } } MainPage.xaml.cs ==End== Attached screenshot of the blank app loading Any help would be appreciated

Hi @ABishop, thanks for the information however when I checked if we have datastore installed it gives the following message: Does this mean that datastore is not installed? What happens in this case? Where would the ArcGIS server store the geotiff?

We are planning to expose rest end to add new raster to imagery server, the REST API for imagery server has a supporting operation to add raster. However the new raster can be added only if it a an item on portal. So if we add a new geotiff using ArcGIS API for Python as a new item on Portal. Where would Portal allocate the memory for hosting the geotiff? Any suggestions would be appreciated! Thank you.

Thank you for replying, this works like charm.

Hi team, We were using ArcGIS AppStudio Desktop 4.8 where we built an app using the quick reporter template. We customized the app using PopupView by importing import Esri.ArcGISRuntime.Toolkit.Controls 100.8 However after the latest update to ArcGIS AppStudio Desktop 5.0 its seems the PopupView type belongs in import Esri.ArcGISRuntime 100.10 https://developers.arcgis.com/qt/toolkit/api-reference/qml-popupview.html Even after importing ESRI.ArcGISRuntime 100.10 I have been getting error stating: I can repoduce the issue with am simple app attached to thread: Any suggestions would be great!

Thanks for the help Erwin, we were able to solve the issue thourgh MapViewer template

Hi team, Based on the popoup sample: Show a popup | ArcGIS for Developers mapView.identifyLayer(featureLayer, screenX, screenY, tolerance, returnPopupsOnly); From the line above in the sample code, I can see we can associate only one layer with popup. However our requirement is to show multiple layer information in single popups. For example we have multiple point features belonging to different feature layers in the sample below: We would like to have all the intersected layers info with respected to point clicked in one popup window like following: The screen shot above is from webmap but it is a good sample to show how we would like to toggle through all the features with help of 1 and 2 in the image above Any suggestions would be helpful! Thank you.

Hi team this white screen issue is related to the previous thread: ArcGIS AppStudio Cloud Make Build for IOS and Android gives white screen We are using QuickReport template On commenting the onComposeError or changing onCompseError to onErrorChanged tha apps are working fine on Android and IPhone however the issue still persists on IPad Following is the configuration of our testing device: We are using the latest version of AppStudio, we are building the apps using CloudMake Any suggestions would be helpful. Thank you

Thanks informing Erwin Cloud make now is working fine.

Hi Team, we have build an using AppStudio for ArcGIS (Desktop) quick reporter template. When we try using cloud build we are getting the following erorr: Any suggestions would be helpful

‎09-25-2020

Hi Erwin, thanks for getting back to us, we figured out the same solution. It was really difficult to identify this issue since we ran on AppStudio Desktop (Player) the error did not popup. Only we started bulding the app from scratch the error was observed. We got this issue on 4.2 all of our existing apps are failing to launch. We are in process in applying edits to the code. Thank you for your time!

Hi Team, We have build an app using ArcGIS AppStudio (Windows) Quick Reporter Template. The app works fine on Appstudio Player, however when we build the app for IOS and Android native and run the .ipa or the .apk on IPhone or Android Phone we are getting blank screen. Any suggestions would be helpful.

You can avoid login prompt with ESRI proxy and add token to proxy config: GitHub - Esri/resource-proxy: Proxy files for DotNet, Java and PHP.
