title: How to use onPause with Android?
body: <p>using <code>onSaveInstanceState(Bundle ..) and onRestoreInstanceState(Bundle ..)</code><br>
  was really good and work, but it is working when click Turn off button on Emulator.<br>
  Now, i want to save state and restore the saved data when below button used:<br>

  <p>I think it is possible to use OnPause() OR oOnStop(), if i am right, How to use it,<br>
  it will be enough to show me Java source of saving one boolean variable, and restore it,<br>
  Thanks.</p>
