title: Orientation issue with landscape mode
body: <p>I am displaying Timer on a screen . </p>
  
  <p>After starting the Timer , I am changing the orientation from the portrait to landscape mode. In order to avoid the timer getting reset when changing from the portrait to landscape mode , I am adding the following code to the <strong>activity declaration in the manifest:</strong></p>
  
  <pre><code>android:configChanges="orientation"
  </code></pre>
  
  <p>The problem I am facing is that , when the screen is switching from the portrait to landscape mode , the layout which gets displayed is same as portrait &amp; not in landscape mode. Only a part of the screen of the landscape orientation is being occupied.</p>
  
  <p>Is there any way by which we can avoid resetting the timer from changing from the portrait to landscape mode &amp; also have a proper landscape layout?</p>
  
  <p>Kindly provide your inputs.</p>
  
  <p>Thanks in advance.</p>
