Android - instead of launch new intent to new class/activity, how go back to open activity/class?
<p>My code allows me to launch a new activity/class:</p>

<pre><code>Intent intent = new Intent(activity1.this, activity2.class); 
startActivity(intent); 
finish(); 
</code></pre>

<p>What if i have an activity already open, and just want to go back to it instead of reopening a new one, thus having multiple open of same.. So i want to switch back to an already open activity/class ?</p>
