How to implement first launch tutorial like Android Lollipop apps: Like Sheets, Slides app?
I have Android 5.0 final build flashed in my Nexus 5. I noticed it has very beautiful, clean and elegant way of showing tutorial at first launch. Apps like "Sheets", "Slides" etc.
How can we implement that in our Android L compatible apps?
Also the app fades off the first launch screen and then shows the tutorial.
Solution 1:
There is a pretty good library for emulating these first run tutorials: https://github.com/PaoloRotolo/AppIntro

First of all, there's no secret. The quality of the illustrations is the key to get this pretty result. So unless you're a designer yourself, you'll have to find a good designer for them.
Appart from that, I can see several ways to get close to this.
First, there's a very subtle parallax effect on the illustrations. You can achieve it by using this ParallaxTransformPage gist. I use it and it works pretty well.
Also, here's a lib that let you smoothly change the screen's background color while switching pages.

For the splashscreen fade out animation, you can do something like this :
final ImageView launchScreen = (ImageView) context.findViewById(R.id.launch_screen_view); new Handler().postDelayed(new Runnable() { @Override public void run() { Animation animation = AnimationUtils.loadAnimation(context, android.R.anim.fade_out); animation.setAnimationListener(new Animation.AnimationListener() { // ... @Override public void onAnimationEnd(Animation animation) { launchScreen.setVisibility(View.GONE); } }); launchScreen.startAnimation(animation); } }, 2000);
