How can I disable the transition after a Google Sign In?

I have found a solution. This works for me. AppTheme was set in android manifest Firebase Login activity theme

styles.xml

<style name="AppTheme" parent="Theme.Material">
   <item name="android:windowAnimationStyle">@style/Replace</item>
</style>

<style name="Replace">
    <item name="android:activityOpenEnterAnimation">@anim/replace_anim</item>
    <item name="android:activityOpenExitAnimation">@anim/replace_anim</item>
    <item name="android:activityCloseEnterAnimation">@anim/replace_anim</item>
    <item name="android:activityCloseExitAnimation">@anim/replace_anim</item>
    <item name="android:taskOpenEnterAnimation">@anim/replace_anim</item>
    <item name="android:taskOpenExitAnimation">@anim/replace_anim</item>
</style>

replace_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

</set>
