Unable to build Netwatch outside the Activity

I am unable to build Netwatch outside the activity because the forceful casting of Context into Activity.
 ```
 public static Builder builder(Context context){
        return Builder.getInstance((Activity) context);
    }
```

With Following exception:
W/System.err: java.lang.ClassCastException: com.atom.vpn.demo.AtomDemoApplicationController cannot be cast to android.app.Activity
