Manipulated Underlying Apps or Android OS
<p>My initial question dealt with building a translucent view that allowed manipulation of a view below it.  Bluefalcon did an excellent job answering this and helped me understand view mechanics a little better: </p>

<p>I'm still unsure of how to manipulate an underlying view that is not part of my app.  The effect I'm trying to achieve is like the Screen Filter App: </p>

<p>In this app, once started, it seems a "filter" view is placed on top of everything but you can still interact with whatever is running under it.  The app store, email, home screen etc.  </p>

<p>I currently have getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE); in my app's onCreate method.  This seems to get close.  If I swipe on my app nothing updates, but when i back out of the app the home screen updates as if i swiped.</p>

<p>Any help will be greatly appreciated!  </p>
