Content going behind Navigation Bar
<p>I am facing a problem with android 5.0 and above. Whenever I align any view to parent bottom, Content is getting hidden behind the soft navigation button.</p>

<p><a href="https://i.stack.imgur.com/qeBvL.png" rel="noreferrer"><img src="https://i.stack.imgur.com/qeBvL.png" alt="Here is the example screen"></a></p>

<p>Above attached is the screenshot of the screen generated after creating new project from Android Studio 1.5. I just added an edit text at the bottom of the fragment.</p>

<blockquote>
  <p>as you can see, half of the edit text is behind the navigation bar.</p>
