Problems when sharing an image #20434

Open cagriy opened 7 months ago

cagriy commented 7 months ago

Description

Hello,

I am trying to share an image from a .NET 8 Maui application. I am using following code:

        await Share.Default.RequestAsync(new ShareFileRequest
        {
            Title = "Share Image",
            File = new ShareFile(targetFile)
        });

I am having two issues which are likely to be related

On other apps, when an image is shared the thumbnail is displayed correctly and file type .png is not displayed, as it is recognised. Please see attached both screenshots, the one with the missing thumbnail is from Maui application.

Expected behaviour: Maui application to not to give errors, recognise the file as an image correctly and display the thumbnail.

image image

Steps to Reproduce

1 - Download the sample app from the public repository and run it 2 - Click button to share 3 - Confirm missing thumbnail, unrecognised file type 4 - Confirm error logs 5 - Continue and save the file locally 6 - Now try to share the saved file from Files application 7 - Confirm that the file is correctly recognised as a PNG and the thumbnail is displayed correctly

    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
