+
+<p>When a TV app launches, the system displays an animation that resembles an expanding, filled
+ circle. To customize the color of this animation, set the <code>android:colorPrimary</code>
+ attribute of your TV app or activity to a specific color. You should also set two additional
+ transition overlap attributes to <code>true</code>, as shown in the following snippet from a
+ theme resource XML file:</p>
+
+<pre>
+<resources>
+ <style ... >
+ <item name="android:colorPrimary">@color/primary</item>
+ <item name="android:windowAllowReturnTransitionOverlap">true</item>
+ <item name="android:windowAllowEnterTransitionOverlap">true</item>
+ </style>
+</resources>
+</pre>
+
