Camera control

Posted on by jft_123

I'm creating a cavas app with 4 screens.

The first screen is a vertical gallery displaying all the information from my datasourse (microsoft List), when the user selects one of the items, there will be a second screen with the detailed information.

The third screen is an editable form where you can add information

The fourth screen is a blank page where I added a camera control and a gallery to display the images the user takes. The pictures taken are stored in a collection.

Everything is working fine and the pictures are being uploaded as attachments in my Sharepoint List. However, I want to display these pictures in the second screen along with the detailed information the user chooses to see.

It's working fine when I preview the app on my computer, the horizontal gallery displays all the pictures. I uploaded the up and when I open it in my phone, the gallery is empty (invisible).

Does anyone know what this could be?

Hi @jft_123 ,

The Mobile App needs to resolve URL-based images anonymously (not needing a log in) and cannot "see" any other connections on the device such as a SharePoint authentication (whereas a browser can). Images in a Library can be displayed by connecting the Library with the App and using the "internal" '{Thumbnail}' property, however attachments use the AbsoluteUri property, which is an "external" URL reference.

So the short answer is that you cannot do this on a Mobile device with attachments.

Hi @WarrenBelz, thanks for the message!

Do you think that there could maybe be a workaround? In the first screen where I have a vertical gallery displaying the info, I was able to display the first image that the user took with the formula (in the image property)
First(ThisItem.Attachments).Value
Can you think of anything that could maybe use this formula in the second screen?

I found a workaround! I added a horizontal gallery with only pictures in the details screen and filtered the data to match one of the fields in my DisplayForm.

Not the best solution but it'll be fine for now! thanks for the help
