1px will be almost invisible on fancy new xxhdpi and xxxhdpi phones. I'd
probably just use 1dp. (Alternatively, you could look at how wide list dividers
in various screen resolution and define a new dimen called divider_width that's,
say, 1px on devices up to xhdpi, and 2px on larger devices. I think list
dividers might just be 1dp, though.)

Also, this will produce a border on all four sides, which is not what we want.
Could you upload a screenshot on the bug? To fix that, you could a) use <inset>
element with insetRight, insetLeft, and insetBottom set to "-1dp", or b) instead
of using a fancy background, change chrome_branding_footer.xml to be a
FrameLayout that contains a View with height 1dp, and a TextView below that.

Done.Opted for the less cool FrameLayout option with 1 dp.
