Images from Sharepoint Load on Desktop Canvas app but not on mobile app

Hi All,

I have created an app where a user takes images on their phone of their items on the app. That image is then stored in their customer folder on SharePoint. I have added a page where they can review their saved images in a gallery from their folder, however I am experiencing an issue where the images only display in the desktop version of the app and not on the mobile.

View on the desktop:

I am resetting the data every time the App loads but other than that I'm not sure what else I can change.

I had a created an app previously which was doing the same thing but from a SharePoint List rather than items in a folder and that seemed to work fine. But for some reason this isn't working now.

Does anyone have any ideas as to what I am missing to display those images on the mobile?

Hello @KamilVK,

Mobile Power Apps often have difficulty rendering images from a SharePoint document library when using a direct URL. This is because the mobile app does not automatically pass the required authentication to SharePoint for those URLs, which works on a desktop browser where the user is already authenticated in the session.

Workaround: Use Power Automate to return image content

Power Apps calls a Power Automate flow

Flow:
1. Gets files from the folder
2. Uses Get file content
3. Returns Base64
4. Image control:

"data:image/png;base64," & ThisItem.ImageBase64

Hi @KamilVK,
Firstly @Kalathiya is correct, however there is a possible alternative solution beyond a Flow. To explain the first bit in another way, a mobile app needs to resolve URL-based images anonymously - in other words without requiring any authentications as the app runs "standalone" as far as the OS/Device is concerned and cannot "see" any other sign-ins from elsewhere on the device. SharePoint requires authentication, which works fine in a PC browser, but not here.

The main reason I posted was to offer an alternative- instead of saving the file path (which you have in varFilePath ) save the ID of the file you are referring to and assuming the image is in the Documents Library (if not, you have added that Library to your data sources), do this
LookUp( SPLibraryName, ID = YourIDVariable ).'{Thumbnail}'.Large
