*  infinite
*  square
*  triangle
*  circle
*  diamond
*  star

lib:balls="3"

Number of balls used in the animation

lib:movement_cycle_time="1500"

The time which the ball takes to do a complete cicle

lib:enable_size_animation="true"

Enables the size animation in the balls (by default is false)

lib:size_cycle_time="500"

The time it takes to the ball to grow up and decrease the size one time

lib:ball_size="6dp"

Set the balls size

lib:min_ball_size="5dp"
lib:max_ball_size="12dp"

To use with enable_size_animation="true", set the min and the max ball size

lib:ball_colors="@array/colors"

Array of colors for the balls, if there are more balls than colors then repeat color balls

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <color name="ball1">#FFD91C</color>
  <color name="ball2">#FF4B4A</color>
  <color name="ball3">#3D8EFF</color>
