Android - How to stop animation between activity changes

I have multiple different Activity in my app and I don't want any transition animation when changing between Activities. Below is the how I'm changing between Activities: ``` Intent i = new Intent(FirstActivity.this, SecondActivity.class); i.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION); i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); startActivity(i); ``` This works great the first time I start a new Activity. There is no animation, but when I go back to an Activity that is already started it seems like the "Intent.FLAG_ACTIVITY_NO_ANIMATION" is ignored and the default animation happens. I can't seem to figure out why this is happening.
