Activity Transition error, cannot resolve symbol '@transition/explode'

Question

I am trying out Activity Transitions and when I paste below code in my values-21/styles.xml I get error:

cannot resolve symbol '@transition/explode'

<style name="BaseAppTheme" parent="android:Theme.Material">
  <!-- enable window content transitions -->
  <item name="android:windowContentTransitions">true</item>

  <!-- specify enter and exit transitions -->
  <item name="android:windowEnterTransition">@transition/explode</item>
  <item name="android:windowExitTransition">@transition/explode</item>

  <!-- specify shared element transitions -->
  <item name="android:windowSharedElementEnterTransition">
    @transition/change_image_transform</item>
  <item name="android:windowSharedElementExitTransition">
    @transition/change_image_transform</item>
</style>

Did you create a res/transition/explode.xml file with the following contents?

<transitionSet xmlns:android="http://schemas.android.com/apk/res/android">
    <explode />
</transitionSet>

You can also use "@android: transition/explode" – George Mount Jan 28 '15 at 05:14
it's `@android:transition/explode` should not use space after `android` – beginner Jun 04 '21 at 07:32
