Xamarin Forms - Android Lollipop java.lang.OutOfMemoryError problem

Hello,

When releasing my app in some Lollipop Devices I got some issues with OutOfMemoryError.

The error always happen in ListViews with images. In this case also CircleImages.

The error is:

java.lang.OutOfMemoryError: Failed to allocate a 18662412 byte allocation with 1643192 free bytes and 1604KB until OOM
    at dalvik.system.VMRuntime.newNonMovableArray(Native Method)
    at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)
    at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:741)
    at android.graphics.BitmapFactory.decodeResourceStream(BitmapFactory.java:562)
    at android.graphics.BitmapFactory.decodeResource(BitmapFactory.java:590)
    at android.graphics.BitmapFactory.decodeResource(BitmapFactory.java:620)

I have already research and tried a lot of solution but none succeed.

Solutions that I tried so far:

1 - From this topic, I tried to call GC.Collector(1) always when an image is compiled. I add a custom renderer like this:

[assembly: ExportRenderer(typeof(Image), typeof(ImageFixRenderer))]   

public class ImageFixRenderer : ImageRenderer
{
    public ImageFixRenderer()
    {
    }

    protected override void OnElementChanged(ElementChangedEventArgs<Image> e)
    {
        base.OnElementChanged(e);
        GC.Collect(1);
    }

    protected override void Dispose (bool disposing)
    {
        try 
        {
            base.Dispose(disposing);
            GC.Collect(1);
        } 
        catch (Exception ex) 
        {
            System.Diagnostics.Debug.WriteLine(ex.ToString ());
        }
    }
}

But it did not worked.

2 - From this topic , I tried to increase my Java Max Heap Size in Android Options, Advanced Tab to 1G.

But it did not worked also.

3 - From this topic, I tried to add android:largeHeap="true" in manifest file.

But not worked too.

Here is my custom CircleImageRender:

public class CircleImageRenderer : ImageFixRenderer
    {
        /// <summary>
        /// Used for registration with dependency service
        /// </summary>
        public static void Init() { }
        /// <summary>
        /// 
        /// </summary>
        /// <param name="e"></param>
        protected override void OnElementChanged(ElementChangedEventArgs<Image> e)
        {
            base.OnElementChanged(e);
            //GC.Collect(1);
            if (e.OldElement == null)
            {

                //Only enable hardware accelleration on lollipop
                if ((int)Android.OS.Build.VERSION.SdkInt < 21)
                {
                    SetLayerType(LayerType.Software, null);
                }

            }
        }

        /// <summary>
        /// 
        /// </summary>
        /// <param name="canvas"></param>
        /// <param name="child"></param>
        /// <param name="drawingTime"></param>
        /// <returns></returns>
        protected override bool DrawChild(Canvas canvas, global::Android.Views.View child, long drawingTime)
        {
            try
            {
                var radius = Math.Min(Width, Height) / 2;
                var strokeWidth = 10;
                radius -= strokeWidth / 2;


                Path path = new Path();
                path.AddCircle(Width / 2, Height / 2, radius, Path.Direction.Ccw);
                canvas.Save();
                canvas.ClipPath(path);

                var result = base.DrawChild(canvas, child, drawingTime);

                canvas.Restore();

                path = new Path();
                path.AddCircle(Width / 2, Height / 2, radius, Path.Direction.Ccw);

                var paint = new Paint();
                paint.AntiAlias = true;
                paint.StrokeWidth = ((CircleImage)Element).BorderThickness;
                paint.SetStyle(Paint.Style.Stroke);
                paint.Color = ((CircleImage)Element).BorderColor.ToAndroid();

                canvas.DrawPath(path, paint);

                paint.Dispose();
                path.Dispose();
                return result;
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine("Unable to create circle image: " + ex);
            }

            return base.DrawChild(canvas, child, drawingTime);
        }
    }

Please I really need help on this. Anyone can give a hint?
