Also, on Samsung mini galaxy, the opacity doesn't work well, hence the circle is showing up as a black circle instead.

Download infobar : Animation improvements for API < 25

Fixed several issues with animation :
1 - Color of the completed download check mark was grey.
Changed it to light blue and smoothened the transition.
2 - For API < 25, when onAnimationEnd() is called,
isRunning() still returns true, hence restartAnimation
bails out early. This is a known android bug, workaround
 is to post the restart method.
3 - The fill animation was not being reset to correct
deep blue color at the beginning of every loop. Fixed it.

kravula@ - Please verify on various versions of android. The animation should look exactly like the spec after this fix.

The fix for this bug fixes :
1 - The color of the circle for completed download (it should be blue as per UX)
2 - The grayed out animation (animation only showed up once) for devices less than N

ok .. we will test next canary.

we are able to see the expected results as mentioned in comment#6 , tested on latest M69 - 69.0.3466.0.
