For Android TV or dongle (e.g. https://store.google.com/product/chromecast_google_tv), such devices only provide a remote to interact with various APPs. It's all based on KeyEvent to interact with APP, and the AppIntroBase.setSwipeLock(Boolean) does not apply to lock current page when user press left/right key.

So, AppIntro may provide a way to lock current page when user using a remote (just like AppIntroBase.setSwipeLock(Boolean) could lock the interaction with touch events). It's useful to develop a tutorial for TV APPs.

For example https://github.com/tmshih/FragmentPager/blob/master/app/src/main/java/com/tms/fragmentpager/view/SwipeableViewPager.java
I'm override the ViewPager.arrowScroll(int) to lock KeyEvent interaction, which may provide a reference.

Yup that makes sense. I believe we can create a protected fun setArrowScrollLock(lock: Boolean) function to toggle this 👍

I'm happy to review a PR to do this if you, or someone else, wish to develop this :)

That's great!
