title: Android: Chronometer save state
body: <p>I have an Android app the will record voice.
  the chronometer view start once the user click on a button and stop once click again.</p>
  
  <p>My problem is the state of the Chronometer, as if the user rotate the device during the record, the activity is rebuild again.</p>
  
  <p>The solution of android:configChanges="orientation|keyboardHidden" in the Manifest is not for me, as the layout is different and as we know the above solution don't change the layout.</p>
  
  <p>I believe that solution is to save the state of the chronometer, but I need suggestion and help from someone.</p>
