Android - display a persistent view over all activities
<p>I'd like to recreate a functionality similar to a Swing GlassPane to be able to display animations while the user uses the app "below" normally. I cannot simply create a separate layout and attach it to each activity since the animation state would be lost when switching activities.
Is there a way to keep a persistent view over all the activities of an Android application ?</p>

<p>Thanks.</p>
