How to animate showcaseview

How can I animate apperance of ShowcaseView?I've tried static method from your samples (animate(true) ) but it doesn't work.

```
public void showFeedTutorial(){
TutoShowcase.from(getActivity())
.setContentView(R.layout.tuto_sample)
.on(viewTutorial)

.addRoundRect(0)
.onClickContentView(R.id.circleLogin, new View.OnClickListener() {
@Override
public void onClick(View view) {

navigateTo(MarketActivity.class);
}
})
.show();
}
```
