SnackBar appear animation

Question

In my app I have a SnackBar that appears when a button is pressed.

Snackbar.make(v, "Enter valid data", Snackbar.LENGTH_SHORT).show();

In the above code, v is the view obtained in the onClick event of a FloatingActionButton.

In the default SnackBar, it appears with a sliding up animation. In my app, the animation doesn't show. It just appears without any animation. Any way to force the animation to show?

Here's the layout file

I ended up running into my Snackbar animations not working also. It turned out to be that I had another app which had accessibility options enabled which disables certain animations such as the Snackbar animation.

See post #5 by Chris: https://code.google.com/p/android/issues/detail?id=206416

The check is AccessibilityManager.isEnabled(), which returns true when any accessibility service is enabled. I've just check on various API levels Snackbar is working fine without an accessibility service enabled.

In my case I had GIF Keyboard installed and enabled as an accessbility option. Going into Settings -> Accessibility and turning off GIF Keyboard made the animations start appearing in my app.
