Progress Animation

[Andreu35]

Hi, Nice work! 👍
But..
I Imagine, the idea is to make this music bar as close as possible to the music bar that Soundcloud uses, right?
So, the animation for progress is not correct, since the animation should be continuous and not advance each bar.
A possible solution for animation is to use Long and not Integer for the times since with Exoplayer2 Long is required for times.

Also, the scroll need to be more flexible, like a normal ScrollView.

Anyway, Good work! Cheers!
