android png from url has its transparency showing as black

I have tried loading a png-8 from a url to an imageview, but the transparency is lost and turns black. So i tried a png-24 and same problem.

Here is the kicker, if I copy the image from the url, and paste it into Photoshop, the transparency is also black!

However on the web, it shows just fine, on iOS, it shows perfectly.

I set my decoder options, and even tried setting my window too in onCreate().

getWindow().getAttributes().format = android.graphics.PixelFormat.RGBA_8888;

then tried this separately

BitmapFactory.Options decOpt = new Options();       
decOpt.inPreferredConfig = Bitmap.Config.ARGB_8888;

then tried them together. These were all the solutions I could find on the web.

this too, doesn't work.

getWindow().getAttributes().format = android.graphics.PixelFormat.TRANSPARENT;

Nothing is working! Any ideas?

Edit:

Here is a url of an image I just randomly tried to see if it was only my image, and no this one has same problem.

and this one as well

So if you can get that one to display correctly in android it would likely fix my problem as well.

Maybe setting the window format will help, in your activity override onAttachedToWindow and set a better pixel format.

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    Window window = getWindow();
    window.setFormat(PixelFormat.RGBA_8888);
}
