Bug fixed:

	public AndroidImageSourceImpl(string name, Func<Stream> streamSource, int quality)
	{
		Name = name;
		_streamSource = streamSource;
		_quality = quality;
		using (var stream = streamSource.Invoke())
		{
			Orientation = Orientation.Normal;
			stream.Seek(0, SeekOrigin.Begin);

			var options = new Options { InJustDecodeBounds = true };
			using (DecodeStream(stream, null, options))
				Bitmap = BitmapFactory.DecodeStream(_streamSource.Invoke()); // bugfix
			Width = Orientation == Orientation.Normal || Orientation == Orientation.Rotate180 ? options.OutWidth : options.OutHeight;
			Height = Orientation == Orientation.Normal || Orientation == Orientation.Rotate180 ? options.OutHeight : options.OutWidth;
		}
	}
