Can't inject [...] when field is not @Nullable

[teo ramone]

I did a post also on StackOverflow here.

I'm injecting an animator resource like this :  @InjectResource(R.animator.button_anim)AnimatorSet animatorSet;

and trying to use it : 

public void secondButton(View v) {
    animatorSet = new AnimatorSet();
    animatorSet.setTarget(button2);
    animatorSet.start();
}

but I get this error : 

1) Error injecting myroboguice.teo.ram.css.myroboguicetest.MainActivity using roboguice.inject.ResourceListener$ResourceMembersInjector@41694450.
Reason: java.lang.NullPointerException: Can't inject null value into class myroboguice.teo.ram.css.myroboguicetest.MainActivity.animatorSet when field is not @Nullable

You’ll need to set up a binding for AnimatorSet if you don’t already have one in your module.
