Blank Screen in Emergency Call UI screen
Blank Screen is observed When Emergency Call is
initiated one after ending other with in a short
gap. The reason for this is CircularRevealAnimation
is not succesfully completed sometimes when Screen
is locked and leading to unhandling CallCardFragment.
With the current design CallCardFragment is shown
only when RevealAnimation is finished succesfully.
The fix is to setup some expiry to the animation
and If Animation is not finished with in expiry
then launch CallCardfragment.The expiry duration
is set as Animation duration + 200ms.
