How can I load a bitmap into an ImageViewAsync on Xamarin Android Native?

You can use LoadStream method, here you will see how to use this method:
ImageService.Instance .LoadStream (GetStreamFromImageByte) .Into (imageView); Here is the GetStreamFromImageByte:
Task<Stream> GetStreamFromImageByte (CancellationToken ct) { //Here you set your bytes[] (image) byte [] imageInBytes = null; //Since we need to return a Task<Stream> we will use a TaskCompletionSource> TaskCompletionSource<Stream> tcs = new TaskCompletionSource<Stream> (); tcs.TrySetResult (new MemoryStream (imageInBytes)); return tcs.Task; } About imageInBytes, you can look here, convert the bitmap to byte[]:
MemoryStream stream = new MemoryStream(); bitmap.Compress(Bitmap.CompressFormat.Png, 100, stream); byte[] bitmapData = stream.ToArray(); I have posted my demo on github.
