Using various animation in page transition

The question is very simple. I'm using ionic framework for android application development. In this im using a function on hardware back button click

$ionicPlatform.registerBackButtonAction(function (event) { 
$state.go("app.home");
}, 100);

I want to change the animation of the page transition to slide-in-up for that specific activity only. The other page transitions are made to slide-left-right already. How to change a specific activity's animation.
