I created an application in Xamarin Forms(iOS) using ArcGISRuntime SDK that listened to GPS location update in the background mode, however, if LocationDisplay is enabled in the MapView (with LocationDisplayAutoPanMode.Recenter), the app would crash when switching into background mode. I have also tried creating a custom location datasource for the LocationDisplay to not call UpdateLocation in background mode, but the error would still occur. Does anyone have any idea where this error came from, and how to get around it? Many thanks! 2016-12-20 16:58:42.880 MobileView[324:134332] critical: Stacktrace: 2016-12-20 16:58:42.881 MobileView[324:134332] critical: at <unknown> <0xffffffff> 2016-12-20 16:58:42.881 MobileView[324:134332] critical: at (wrapper managed-to-native) ObjCRuntime.Messaging.bool_objc_msgSend_nuint (intptr,intptr,System.nuint) <0x00007> 2016-12-20 16:58:42.882 MobileView[324:134332] critical: at OpenGLES.EAGLContext.PresentRenderBuffer (System.nuint) [0x0000b] in /Users/builder/data/lanes/3539/f37444ae/source/maccore/src/build/ios/native/OpenGLES/EAGLContext.g.cs:106 2016-12-20 16:58:42.882 MobileView[324:134332] critical: at Esri.ArcGISRuntime.UI.Controls.GeoView.RequestRender (bool) <IL 0x0008c, 0x002ef> 2016-12-20 16:58:42.882 MobileView[324:134332] critical: at Esri.ArcGISRuntime.UI.Controls.GeoView.RuntimeCoreNet.GeneratedWrappers.ICoreCallback_GeoView_DrawRequested.DrawRequested () <IL 0x00011, 0x000cb> 2016-12-20 16:58:42.883 MobileView[324:134332] critical: at RuntimeCoreNet.GeneratedWrappers.CoreGeoView.onPrivateCoreGeoView_DrawRequested (intptr) <IL 0x00031, 0x001e7> 2016-12-20 16:58:42.883 MobileView[324:134332] critical: at (wrapper native-to-managed) RuntimeCoreNet.GeneratedWrappers.CoreGeoView.onPrivateCoreGeoView_DrawRequested (intptr) <0x00097> 2016-12-20 16:58:42.884 MobileView[324:134332] critical: Native stacktrace: 2016-12-20 16:58:43.468 MobileView[324:134332] critical: 0 MobileView 0x00000001000784d4 mono_handle_native_sigsegv + 260 2016-12-20 16:58:43.469 MobileView[324:134332] critical: 1 MobileView 0x0000000100081c88 mono_sigsegv_signal_handler + 336 2016-12-20 16:58:43.469 MobileView[324:134332] critical: 2 libsystem_platform.dylib 0x0000000181ab994c _sigtramp + 68 2016-12-20 16:58:43.469 MobileView[324:134332] critical: 3 libGPUSupportMercury.dylib 0x000000019041aec4 gpusSubmitDataBuffers + 172 2016-12-20 16:58:43.469 MobileView[324:134332] critical: 4 GLEngine 0x0000000194c1b1e4 <redacted> + 176 2016-12-20 16:58:43.470 MobileView[324:134332] critical: 5 GLEngine 0x0000000194c1b0fc gliPresentViewES + 84 2016-12-20 16:58:43.470 MobileView[324:134332] critical: 6 OpenGLES 0x0000000183fb7c44 <redacted> + 72 2016-12-20 16:58:43.470 MobileView[324:134332] critical: 7 MobileView 0x00000001022b3ae0 wrapper_managed_to_native_ObjCRuntime_Messaging_bool_objc_msgSend_nuint_intptr_intptr_System_nuint + 112 2016-12-20 16:58:43.470 MobileView[324:134332] critical: 8 MobileView 0x0000000101df66c0 OpenGLES_EAGLContext_PresentRenderBuffer_System_nuint + 80 2016-12-20 16:58:43.470 MobileView[324:134332] critical: 9 MobileView 0x0000000103193d90 Esri_ArcGISRuntime_UI_Controls_GeoView_RequestRender_bool + 752 2016-12-20 16:58:43.471 MobileView[324:134332] critical: 10 MobileView 0x0000000103194bfc Esri_ArcGISRuntime_UI_Controls_GeoView_RuntimeCoreNet_GeneratedWrappers_ICoreCallback_GeoView_DrawRequested_DrawRequested + 204 2016-12-20 16:58:43.471 MobileView[324:134332] critical: 11 MobileView 0x0000000102e8db78 RuntimeCoreNet_GeneratedWrappers_CoreGeoView_onPrivateCoreGeoView_DrawRequested_int ptr + 488 2016-12-20 16:58:43.471 MobileView[324:134332] critical: 12 MobileView 0x000000010363bcf8 wrapper_native_to_managed_RuntimeCoreNet_GeneratedWrappers_CoreGeoView_onPrivateCoreGeoView_DrawRequested_intptr + 152 2016-12-20 16:58:43.471 MobileView[324:134332] critical: 13 ArcGIS-arm64 0x000000010bf7066c _ZNK16Esri_runtimecore7Mapping6SignalIKNS0_8Geo_viewEJEEclERS3_ + 744 2016-12-20 16:58:43.472 MobileView[324:134332] critical: 14 ArcGIS-arm64 0x000000010bd2f6e0 _ZN16Esri_runtimecore7Mapping23Geo_view_draw_requested21draw_request_callbackEv + 48 2016-12-20 16:58:43.472 MobileView[324:134332] critical: 15 ArcGIS-arm64 0x000000010badd408 _ZN16Esri_runtimecore12Map_renderer3Map9on_pulse_Ev + 2340 2016-12-20 16:58:43.472 MobileView[324:134332] critical: 16 ArcGIS-arm64 0x000000010baf0ea0 _ZN16Esri_runtimecore12Map_renderer12Pulse_thread8execute_Ev + 124 2016-12-20 16:58:43.472 Mobil eView[324:134332] critical: 17 ArcGIS-arm64 0x000000010b1ae464 _ZN16Esri_runtimecore6Common6Thread11thread_procEPS1_ + 84 2016-12-20 16:58:43.473 MobileView[324:134332] critical: 18 ArcGIS-arm64 0x000000010bc21c0c _ZNSt3__114__thread_proxyINS_5tupleIJPFvPN16Esri_runtimecore6Common6ThreadEES5_EEEEEPvS9_ + 92 2016-12-20 16:58:43.473 MobileView[324:134332] critical: 19 libsystem_pthread.dylib 0x0000000181abfb28 <redacted> + 156 2016-12-20 16:58:43.473 MobileView[324:134332] critical: 20 libsystem_pthread.dylib 0x0000000181abfa8c <redacted> + 0 2016-12-20 16:58:43.473 MobileView[324:134332] critical: 21 libsystem_pthread.dylib 0x0000000181abd028 thread_start + 4 2016-12-20 16:58:43.473 MobileView[324:134332] critical: ================================================================= Got a SIGSEGV while executing native code.

When installing ArcGIS Javascript API, how do I specify the server url for the child modules?  The main modules loaded by the handler (default.ashx) have the correct url (e.g. http://servername/library/3.1/jsapi), but the child modules still get loaded from the serverapi.arcgisonline.com, e.g. http://serverapi.arcgisonline.com/jsapi/arcgis/3.1/js/dojo/dojox/gfx/svg.js. The installation guide mentioned the following, do I need ArcGIS Server for this?  I have ArcGIS Server 10.1 installed, with the web adapter, but I couldn't find where to configure this.  Do you mind explaining how it works and how to configure it? Thanks a lot in advance! �?�Change the ArcGIS Services Directory "View In JavaScript" URL. Instructions are given in "Configuring the REST API" in the ArcGIS Server REST SDK. On Windows, the location is <Installation Location>\DeveloperKit\Help\REST\index.html. On UNIX and Linux, the location is http://<myserver>:8399/<instance>/sdk/rest/index.html where myserver is your server name and instance is the instance name (jsapi is the default). �?�Find the "JavaScript API" section for either .NET or Java for more information about parameter values. �?�For .NET, the parameters to change in rest.config are <ArcGIS> and <ArcGISCSS>. Replace serverapi.arcgisonline.com with your server domain name. �?�For Java, the parameters to change in rest-config.properties are jsapi.arcgis and jsapi.arcgis.css. Replace serverapi.arcgisonline.com with your server domain name. Thanks, Feichi ... View more

We run into an issue with the BasemapGallery.js, FeatureLayer.js and a few other modules throwing the ieDefineFailed error when dojoLoader attempts to load the module in FireFox, Chrome, and Safari (IE works fine).  This happens when we try to embed a map inside a div tag that is dynamically generated at run time by the Microsoft PerformancePoint AJAX framework. The modules load fine otherwise in a regular Html page. After looking into it further, we notice that ArcGIS Server 3.1 Javascript API uses dojo 1.7, and the AMD define method in these modules are missing the optional id argument.  Adding the id actually fix the error for us.  define("featureLayer",["dijit", "dojo", "dojox", "dojo/require!esri/layers/graphics,esri/tasks/query,dojo/io/iframe,esri/layers/agscommon,dojo/date/locale"], function(_1, _2, _3) { We did this by overwriting the scripts with custom copies hosted locally, but it would be nice if the server API would work too, would it be possible to have the 3.1 API be updated to include the id argument on all modules?
