Disable bitmap filtering on Android Canvas

I am trying to display simple pixel art on a canvas, but it gets displayed blurry because of anti-aliasing, bilinear filtering, or possibly something similar. For as far as I know I have no way to identify it specifically.

Other people have asked the same question before, but the answers seem to be very outdated.

What I basically have at the moment:

paint = new Paint();
paint.setAntiAlias(false);
paint.setDither(true);
paint.setFilterBitmap(false);

bitmap = BitmapFactory.decodeResource(res, R.drawable.image);
bitmap = Bitmap.createScaledBitmap(bitmap , 320, 320, false);

canvas.drawBitmap(bitmap , 30, 50, paint);

Edit 1

I've come to the conclusion that it is definitely not anti-aliasing since that would actually try to make the borders smooth. Can anyone recognize what is actually happening?

I added the following code in addition to what you did, and it seems to work.

 BitmapFactory.Options options = new BitmapFactory.Options();
    options.inScaled = false;
    options.inDensity = options.inTargetDensity ;

    forestBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.forest_bkg, options);
