How to create shimmer effect around a custom path in android

I want shimmer effect in circular path around a circular view. How can i achieve this ?
This library supports only  4 values for shimmer_direction
```
<enum name="left_to_right" value="0"/>
      <enum name="top_to_bottom" value="1"/>
      <enum name="right_to_left" value="2"/>
      <enum name="bottom_to_top" value="3"/>
```
