title: Shadow too light for Floating Action Button
body: <p>I have some Floating Action Button in my app. For all those FAB the shadow is too light. I have tried many solutions like elevation, borderwidth = 0dp, translationz, using drawable file and using styles. Those did not solve the problem and the shadow remains light.</p>
  
  <p>You can check my screenshot for the light shadow that I get in my app </p>

  <p>This is the manifest:</p>

   &lt;/application&gt;
  </code></pre>
