Add SaveToGallery option to MediaPickerOptions for capture operations by Copilot · Pull Request #34641 · dotnet/maui

Copilot · 2026-03-25T13:11:12Z

Add SaveToGallery property to MediaPickerOptions (default false)
iOS: Request PhotosAddOnly permission and save to photo library only when SaveToGallery=true
Android: Request StorageWrite (API < 29) / MediaStore insert (API 29+) only when SaveToGallery=true
macOS/MacCatalyst: Uses same iOS code path (shared .ios.cs file)
Windows: Documented as not supported in API docs (property ignored)
Tizen/netstandard: Property ignored (no save-to-gallery support)
Update all PublicAPI.Unshipped.txt files with new API entry
Update Essentials sample to add SaveToGallery toggle
Merged net11.0 branch into PR — PR base should be changed to net11.0

… implementations Add a new `SaveToGallery` boolean property (default: false) to `MediaPickerOptions`. When true during capture operations, the captured image/video is saved to the device photo gallery and the necessary permissions are requested. iOS/macOS: Uses PHPhotoLibrary.PerformChangesAsync with PHAssetChangeRequest. Requests PhotosAddOnly permission only when SaveToGallery is true. Android: Uses MediaStore ContentResolver insert for API 29+. Requests StorageWrite permission only when SaveToGallery is true on older API levels. Windows/Tizen: Property is ignored (not supported, documented in API docs).

@copilot this should target the net11.0 branch. Update the target and rebase on that.

@copilot this should target the net11.0 branch. Update the target and rebase on that.

Done — I merged origin/net11.0 into the branch and resolved PublicAPI conflicts (commit 5f4436b4). The branch now includes all net11.0 content. However, I'm unable to change the PR's base branch programmatically — could you update the base from main to net11.0 in the PR settings? Once changed, the diff should show only the ~12 files with the SaveToGallery changes.

Will probably have a conflict with #34287 when that is merged up to the net11.0 branch. Afterwards I think this will be nice to have for .NET 11.

Pull request overview

Adds an opt-in SaveToGallery flag to MediaPickerOptions so capture operations can avoid requesting gallery/photo-library permissions unless the app explicitly asks to save captured media to the user’s gallery.

Changes:

Introduces MediaPickerOptions.SaveToGallery (default false) with platform behavior documented in XML docs.
Updates iOS and Android capture flows to conditionally request permissions and save captured media to the gallery/library when enabled.
Updates PublicAPI unshipped files and the Essentials sample UI to expose a “Save to Gallery” toggle.

The XML summary says that on Android versions below API 29 this method uses a direct file copy, but the implementation still uses a MediaStore insert + OpenOutputStream for all API levels. Please either adjust the comment to match the actual approach, or implement the documented pre-29 behavior so the comment stays accurate (and make sure the pre-29 path results in the media being visible in the gallery).

+				using var stream = await fileResult.OpenReadAsync();
+				var extension = System.IO.Path.GetExtension(fileResult.FileName);
+				var tempPath = System.IO.Path.Combine(System.IO.Path.GetTempPath(), $"{Guid.NewGuid()}{extension}");
+				using (var fileStream = File.Create(tempPath))
+				{
+					stream.Position = 0;
+					await stream.CopyToAsync(fileStream);
+				}


If the stream copy or PHPhotoLibrary.PerformChangesAsync throws, tempPath won’t be deleted because cleanup happens only after the await. Consider using a try/finally (or similar) so the temporary file is always removed even on failure. Also consider guarding stream.Position = 0 with stream.CanSeek (or removing it) to avoid NotSupportedException for non-seekable streams.
