title: completely transparent status bar and navigation bar on lollipop
body: <p>I'm trying to make an android launcher. I want to achieve a completely transparent status bar and navigation bar, here is my theme xml file.</p>
  
  <pre><code>&lt;resources&gt;
      &lt;style name="Theme" parent="android:Theme.Material.Wallpaper.NoTitleBar"&gt;
          &lt;item name="android:statusBarColor"&gt;@android:color/transparent&lt;/item&gt;
          &lt;item name="android:navigationBarColor"&gt;@android:color/transparent&lt;/item&gt;
          &lt;item name="android:windowTranslucentStatus"&gt;false&lt;/item&gt;
          &lt;item name="android:windowTranslucentNavigation"&gt;false&lt;/item&gt;
      &lt;/style&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>the last two items don't work, there is still a shadow on lollipop.</p>
  
  <p>This is what it looks like(note there is actually a shadow on status bar and navigation bar):

  <p>how to make the status bar and navigation bar "transparent" instead of "translucent"?</p>
