<h3 id="transition-color">Change the launcher color</h3>
<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>
&lt;resources&gt;
&lt;style ... &gt;
&lt;item name="android:colorPrimary"&gt;&#64;color/primary&lt;/item&gt;
&lt;item name="android:windowAllowReturnTransitionOverlap"&gt;true&lt;/item&gt;
&lt;item name="android:windowAllowEnterTransitionOverlap"&gt;true&lt;/item&gt;
&lt;/style&gt;
&lt;/resources&gt;
</pre>
