This bug doesn't exit after #92 got merged. But now the bar doesn't show any progress at all. That is no colour changes on completing an level of the activity.
Even though I completed various levels, there was no progress in the bar at the bottom.

@paavininanda can you please close this and open a new one for the new bug in that case?

Also to match when I'm drawing the lines, I was never able to do it at the first time. We may want to increase the empty circle region for starting our line.

@Buddhiprabha I updated the description and the title. Should I still open a separate issue?
