FFImageLoading fails load big Gif file when executing real device

My Xamarin.Forms app uses FFImageLoading for loading three Gifs.

A.gif : 3.7MB
B.gif : 5.1MB
C.gif : 2MB

(These Gifs created by DavinciResolve)

My app preload Gifs as following.

public static async void PreloadTutorialGifs()
{
    try
    {
        var targetWidth = 500;
        var targetHeight = 1000;
        await ImageService.Instance.LoadFileFromApplicationBundle("A.gif").Success((info, result) =>
        {
            Debug.WriteLine($"A.gif Preloading finished! Key: {info.CacheKey}");
        })
        .CacheKey("A.gif")
        .DownSample(targetWidth, targetHeight)
        .PreloadAsync();
        await ImageService.Instance.LoadFileFromApplicationBundle("B.gif").Success((info, result) =>
        {
            Debug.WriteLine($"B.gif Preloading finished! Key: {info.CacheKey}");
        })
        .CacheKey("B.gif")
        .DownSample(targetWidth, targetHeight)
        .PreloadAsync();
        await ImageService.Instance.LoadFileFromApplicationBundle("C.gif").Success((info, result) =>
        {
            Debug.WriteLine($"C.gif Preloading finished! Key: {info.CacheKey}");
        })
        .CacheKey("C.gif")
        .DownSample(targetWidth, targetHeight)
        .PreloadAsync();
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
        Utility.SendExceptionToCrashlytics(ex);
    }
}

Solution

What is original width and height of gif.A?
How many frames?
In memory each pixel takes 4 bytes. Multiply "4 * original width * height * #frames".
What value do you get? That's what will be needed in cache size to "load the gif". Note that it doesn't matter how small the file is on disk; that is "compressed" size. In memory, it is not compressed. It also doesn't matter how small you are downsampling to; it first loads at the original size [I think].

To fix, do EITHER:

In an image editor, shrink to a smaller width/height.
OR Set a custom cache size for FFImageLoader, from Memory size is greater than image sizes?:

var config = new FFImageLoading.Config.Configuration()
{
    MaxMemoryCacheSize = 9999999, // Try different values here. Bigger uses more app memory.
};
ImageService.Instance.Initialize(config);
