Question: does the phone-ringing animation use spring animation?

[AndroidDeveloperLB]

I'm talking about this:

If not, what does it use? Can the physics animation library help to do something like that ? To me it seems it starts from center, and goes left and right of it.

Hey, Not sure phone ringing animation uses physics animation.

But it is possible using physics animation. It seems like animation is divided into 2 parts

1. Vertical translation
2. Horizontal spring animation

I just wanted the "wiggling" animation to be smooth and natural. Also not sure how I could do it using the normal API, as it needs to do animation in X coordinate of : 0 -> (-10) -> 10 -> 0

I think I got something similar to what you see on the Phone app: RingingWiggleShakeAnimationTest.zip

Need some work on this. Still doesn't look so fluid and natural...

Are using linear interpolator for translation y animation ?

If yes I would recommend some other interpolator to make it smooth

Never mind saw your code. You are using FastOutSlowInInterpolator

It's a bit hard to see it in the animation here. Not enough FPS...

You can try the sample yourself too.

BTW, I tried to convert your sample to Android-X. Got a weird issue there: https://issuetracker.google.com/issues/111316650

Navigation is not compatible with androidx. It will be available in future release.

How do you know this?
