[Bug] On IOS, Photo returned by MediaPicker.CapturePhotoASync() is not found

[euquiq]

Description

On Android this works as expected.

On IOS, when I try to get the photo taken by MediaPicker as a file, for i.e. get it's size, I get:

Length	System.IO.FileNotFoundException: Could not find file '/private/var/containers/Bundle/Application/BCB43D5F-508C-4882-BFB5-70C6953F6855/Myapp.iOS.app/fa637fb7-0b37-4896-bc33-cd3b5738f548.png'.	

There is a PR that apparently fixes this: https://github.com/xamarin/Essentials/pull/1639

Steps to Reproduce

1. var photo = await MediaPicker.CapturePhotoAsync();
2. var file = new FileInfo(photo.FullPath);
3. file.Length throws the "FileNotFoundException".

Expected Behavior

Be able to access the file.

Actual Behavior

File not found.

@euquiq - Try this code:

var stream = await imagePicker.OpenReadAsync(); byte[] dataBytes = new byte[stream.Length]; var streamData = await stream.ReadAsync(dataBytes, 0, dataBytes.Length);

var cacheFile = System.IO.Path.Combine(Xamarin.Essentials.FileSystem.CacheDirectory, "filename.png"); using (var cache = new FileStream(cacheFile, FileMode.Create, FileAccess.Write)) { cache.Write(dataBytes, 0, dataBytes.Length); await cache.FlushAsync(); }

Replace "filename.png" with the filename. The code must be placed in the iOS implementation and can be passed back with the correct path to the image.

@sshere Thx, You saved my day!!!

The FullPath of the file just seems wrong at first. So resaved it, in Cache directory made it work for me.

var file = await MediaPicker.CapturePhotoAsync();
var cachePath = Path.Combine(FileSystem.CacheDirectory, file.FileName);
using (var stream = await file.OpenReadAsync())
using (var cache = new FileStream(cachePath, FileMode.Create, FileAccess.Write))
        await stream.CopyToAsync(cache);

Bug still not fixed (Essentials v 1.7.3)

Bug still not fixed (Essentials v 1.7.3) Hi @yevgeny-sotnikov !) For me not fixed as well

Same here... still not working on Xamarin.Essentials v1.7.7. The Android implementation works fine, and returns a FileResult with the FileName and FullPath set properly. Meaning... The fullpath includes the complete path to the folder... and the filename.

But, the iOS implementation returns the same string value for both properties. And, trusting the "FullPath" property to be what it says, results in an exception.

Is there a fix for this?

[LeeWhite187]

Since the iOS implementation doesn't give a correct FullPath to the taken photo, how should I delete the orphaned file in iOS if I'm consuming the stream, instead?
