How to save video to album of cellphone in maui ?

Hello,

You could refer to the following code to implement this feature on Android and iOS:

For Android

public static class SaveVideoService
{
    public static bool SaveVideo(byte[] arr, string imageName)
    {
        var contentValues = new ContentValues();
        contentValues.Put(MediaStore.IMediaColumns.DisplayName, imageName);
        contentValues.Put(MediaStore.Files.IFileColumns.MimeType, "video/mp4");
        contentValues.Put(MediaStore.IMediaColumns.RelativePath, "Pictures/relativePath");
        try
        {
            var uri = MainActivity.Instance.ContentResolver.Insert(MediaStore.Video.Media.ExternalContentUri, contentValues);
            var output = MainActivity.Instance.ContentResolver.OpenOutputStream(uri);
            output.Write(arr, 0, arr.Length);
            output.Flush();
            output.Close();
        }
        catch (System.Exception ex)
        {
            Console.Write(ex.ToString());
            return false;
        }
        contentValues.Put(MediaStore.IMediaColumns.IsPending, 1);
        return true;
    }
}

For iOS:

public static class SaveVideoService
{
    public static void SavePicture(string path)
    {
        var videoCompatible = UIVideo.IsCompatibleWithSavedPhotosAlbum(path);
        //Check that the video can be saved to an album
        if (videoCompatible)
        {
            UIVideo.SaveToPhotosAlbum(path, (s, e) => {

            });
        }
        else
        {
            Console.WriteLine("The video cannot be saved to an album");
        }
    }
}

You could invoke those services on MAUI as the following code:

#if ANDROID
            MauiApp22.Platforms.Android.SaveVideoService.SaveVideo(b, "test.mp4");
#elif IOS
            SaveVideoService.SaveVideo(localFilePath);
#endif
