Null pointer exception when setting it to checked in recyclerview #1

Hi there, The fork you created seems to be working well, however I am having a null pointer exception when setting the switch through a recyclerview. I tried forking it and made this update but did not work. You can take a look at it here: https://github.com/AkshayPathak/material-animated-switch/commit/1a10028c3ad105d5353f036a5b4c786c77f044f7.

So instead I tried doing a check like this: 

if (isSwitchEnabled && !holder.switchIsEnabled.
    holder.switchIsEnabled.toggle();
} else if (!isSwitchEnabled && holder.switchIsEnabled.isChecked()) {
     holder.switchIsEnabled.toggle();
}

but this is giving me this exception:

java.lang.NullPointerException: Attempt to invoke virtual method 'void com.nineoldandroids.animation.ValueAnimator.start()' on a null object reference
