Just making sure, is this is a JavaScript app? And, are you programmatically making your own ArcGIS REST API calls for editing attachments in a feature service?  If so, then attachments are handled using addAttachment, updateAttachment and deleteAttachments.  With respect to your attachments, when you do add an attachment I recommend using FormData to create your XMLHttpRequest:     // Example when adding an attachment     var formData = new FormData();     formData.append("attachment",file);‍‍‍‍     // Example when updating an attachment     formData.append("attachmentId", attachment.id);‍‍‍‍‍‍‍‍‍‍‍‍ You can see an example of working with attachments using the ArcGIS JavaScript API and the attachment widget here: SanFrancisco311 - Incidents  Here's an example of the HTTP request when making an addAttachment. You can see this for yourself in the browser's developer tools under the network tab.  ------WebKitFormBoundary1aQsyoAkAGZU7oKM Content-Disposition: form-data; name="attachment"; filename="Blue Lake.jpg" Content-Type: image/jpeg ------WebKitFormBoundary1aQsyoAkAGZU7oKM Content-Disposition: form-data; name="f" json ------WebKitFormBoundary1aQsyoAkAGZU7oKM--‍‍‍‍‍‍‍‍ If a request is successful you'll see a response in the network tab similar to this: {   "addAttachmentResult" : {      "objectId" : 7369,      "globalId" : null,      "success" : true   } }‍‍‍‍‍‍‍ -Andy ...

Logan, as Yue pointed out the quickstart-map-phonegap repo does have 4.x samples. You have to wait for Cordova's onDeviceReady to fire before loading the ArcGIS API for JavaScript.  ... View more

I recommend checking out the ArcGIS DevLabs: Get Started with ArcGIS DevLabs | ArcGIS for Developers. They are designed to help walk you thru how the pieces fit together starting at working with geographic Data, learning about cartographic Design and then pulling it all together in an application that you Develop. ...

Josh, the name pattern in the URL determines whether or not anonymous will work with ArcGIS Online. Only the anonymous access approach allows both HTTP and HTTPS. Here are a few examples to hopefully illustrate the point a bit better. Example 1: this uses the ArcGIS Online organization's name in the URL and it will prompt you for a log in. There is no anonymous access using this pattern and it requires HTTPS: https://hack4co.maps.arcgis.com/home/webmap/viewer.html?webmap=06a23f2572014ebcbbbb1953688d2724  Example 2: this uses, HTTP plus www.arcgis.com in the URL and is open for anonymous access, no log in required: http://www.arcgis.com/home/webmap/viewer.html?webmap=06a23f2572014ebcbbbb1953688d2724  Example 3: switch out HTTP in Example 2 with HTTPS and this webmap still works for anonymous access, no log in required: https://www.arcgis.com/home/webmap/viewer.html?webmap=06a23f2572014ebcbbbb1953688d2724  ...

Hi Rachel, ArcGIS Online is already HTTPS-enabled. More details can be found here. Quoting from that article, here’s the relevant bits that I believe apply to your question: “If you've disabled anonymous access to your organization, you can share maps, apps, and groups by sharing the item with everyone (public) and changing the URL of the item from your organization's private URL to the public ArcGIS Online URL (www.arcgis.com). For example, you could share one of your organization's maps with anonymous users by changing the URL from https://samplegis.maps.arcgis.com/home/webmap/viewer.html?webmap=fb39737f95a74b009e94d2274d44fd55 to https://www.arcgis.com/home/webmap/viewer.html?webmap=fb39737f95a74b009e94d2274d44fd55.” Does that help? ...

Firefox is looking into similar functionality. You can read the details here under Bug 1072859 – Disable Geolocation on non-secure origins  Not sure about IE. And, I haven't seen anything from the Microsoft Edge team yet. The status of Geolocation in Microsoft Edge is Shipped - Microsoft Edge Development  ... View more

As of Safari 10, insecure geolocation is no longer allowed. Unfortunately, Safari 9.x didn't give any warning messages about the up coming change. The only place I had seen an official reference to this was in the Safari 10 Technology Preview Release Notes under Web APIs: "Started blocking Geolocation API calls on pages served over insecure connections". I'll make sure this info is passed onto the core JS API team. Additional references on StackOverflow: ios10 - Got an error when trying to get the geolocation in safari on iOS 10 - Stack Overflow  ...

Gotcha.  Right, two other options are migrate to another browser or go to a hybrid approach. PhoneGap/Cordova uses plug-ins that can bypass the browser's Geolocation API, for example: cordova-plugin-advanced-geolocation. ... View more

Hey Josh, sorry for the late reply. Not sure why, but I didn't get a notification of your post.  Do you still have the problem or has it been resolved? ... View more

New information update for Mac OS users as of Feb 2016. If you are testing a geolocation-based web app on Chrome locally you will have to use 'localhost' or '127.0.0.1'. Virtual hosts on Apache will result in the Geolocation API throwing the following error: " Only secure origins are allowed" and you won't be able to get a location. ... View more

Mele, For now apps using the browser's Geolocation API will continue to work on Chrome with HTTP, but they will trigger a security indicator. At some point in the future that will change and geolocation-based apps will no longer work on HTTP. The best I can tell the Chromium team hasn't set a hard date, yet. You can read the implementation specifics in the latest working draft of the W3C Secure Contexts document. That's the document that applies to all browser vendors, not just Chrome. The web is moving in direction of making everything HTTPS, and it's a security best practice to use HTTPS whenever possible. If one map service is HTTPS-based then all services used by the app will have to be HTTPS, it's an all-or-nothing proposition. ... View more

Seth, I'm not sure what the issue is, however if you have a geometry point you can always force the map to center on it using map.centerAt() or map.centerAndZoom(). ... View more

Christian, it looks like this may be a bug in either Chrome and/or the Google Location Service. The Google Location Service is what provides the browser with your location in absence of a GPS (e.g. when testing from a laptop). You can follow the conversation with the Chromium folks here. As I get more information I'll post updates. ... View more
