Manually set vector density when converting to bitmap.

            VectorDrawable vectorDrawable) {

        Bitmap bitmap = Bitmap.createBitmap(vectorDrawable.getIntrinsicWidth(),

                vectorDrawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);

        // BitmapDrawables and Bitmap have a default density of DisplayMetrics.DENSITY_DEVICE,

        // (which is deprecated in favor of DENSITY_DEVICE_STABLE/resources.densityDpi). In

        // rare cases when device density differs from the resource density, the bitmap will

        // scale as the BitmapDrawable is created. Avoid by explicitly setting density here.

        bitmap.setDensity(resources.getDisplayMetrics().densityDpi);

        Canvas canvas = new Canvas(bitmap);

        vectorDrawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());

        vectorDrawable.draw(canvas);
