default android animation on activity

[MBethDev]

Hello,

Does anyone know what animation is getting triggered when I exit an
application (the animation where the exiting activity/app shrinks and
disappears?) I'm able to find in the frameworks/base/core what
attribute is triggering this (wallpaperCloseExitAnimation), but when I
checkout the source of the animation (wallpaper_close_exit.xml), it
looks like it does an expansion with no alpha, by default. I saw some
animations that were commented, so i commented one of them to see if
that was the one (basically the second commented <set>), but after
running that its not the same as the animation on the emulator SDK.

The possible animations are in frameworks/base/res/res/values/attrs.xml:

    <!-- Window animation class attributes. -->

    <declare-styleable name="WindowAnimation">

        <!-- The animation used when a window is being added. -->

        <attr name="windowEnterAnimation" format="reference" />

        <!-- The animation used when a window is being removed. -->

        <attr name="windowExitAnimation" format="reference" />

        <!-- The animation used when a window is going from INVISIBLE to VISIBLE. -->

        <attr name="windowShowAnimation" format="reference" />

        <!-- The animation used when a window is going from VISIBLE to INVISIBLE. -->

        <attr name="windowHideAnimation" format="reference" />

        

        <!--  When opening a new activity, this is the animation that is

              run on the next activity (which is entering the screen). -->

        <!--  When sending the current task to the background, this is the

Hey! 

Do you know what ID/INT the enter/exit animations have? I'm trying to only configure one of the animations on pending, but I only know of that which is mentioned at developers android, which is 0 for no animation.

    overridePendingTransition(0,R.anim.fadestar); //What to use where 0 is to make it not change from the default.

 
Thanks..
