onBackPressed to hide Not destroy activity
<p>i know how to cancel back keypress, so that the activity / main window stays visible:</p>

<pre><code>public void onBackPressed() {
    return;             
}
</code></pre>

<p>my aim is to hide the activity, however, without finishing it, how do you do that in the onBackPressed event? </p>

<p>i.e. I would like to get as far as onPause(), but not evoke the onBackPressed() default behaviour that essentially calls finish(). another way to put it is that i would like to mimic onUserLeaveHint() ?</p>

<p>any help appreciated!</p>
