 <p>On Android 5.0 this has changed, you have to call setElevation(0) on your action bar. Note that if you're using the support library you must call it to that like so:</p> <pre><code>getSupportActionBar().setElevation(0); </code></pre> <p>It's unaffected by the windowContentOverlay style item, so no changes to styles are required </p>
