black header when transition an activity
<p>I have the following slide affect from bottom to top:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;set xmlns:android="http://schemas.android.com/apk/res/android" 
     android:interpolator="@android:anim/decelerate_interpolator"&gt;
&lt;translate android:fromYDelta="100%p"
            android:toYDelta="0%p"
            android:duration="300" /&gt;
</code></pre>

<p></p>

<p>I'm calling "overridePendingTransition" to activate this transition when starting the new activity.</p>

<p>The problem is that I see a small black header on top of the new activity (it's black, not red):

<p>Any idea why?</p>
