Activity B launch mode : SingleTask

Answer 1

First Solution One way to solve this is launch No UI Activity(RouterActivity) from deeplink and form this activity you can try launch with animation. Inside Router Activity set theme in onCreate.

 getTheme().applyStyle(R.style.NO_UI, true);

In style

  <style name="Theme.NO_UI" parent="AppTheme">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">true</item>
</style>

And launch screen with animation from onCreate().

Second Solution Define animation in style: Define a new animation style in your styles.xml, as follows

    <style name="MyTheme.Window" parent="@android:style/Animation.Activity">
      <item name="android:activityOpenEnterAnimation">@anim/your_desired_animation</item>

Then set this style in a theme (themes.xml) as follows :

<style name="MyTheme" parent="@android:style/Theme">
      <item name="android:windowAnimationStyle">@style/MyTheme.Window</item>
</style>

And then you can simply set these themes to every activity in your AndroidManifest.xml as follows:

<activity 
  android:name="your_activity" 
  android:theme="@style/MyTheme">
</activity>
