Go back to previous screen without creating new instance
<p><img src="http://i.stack.imgur.com/z77Wy.jpg" alt="enter image description here"></p>

<p>As explained in image, flow is something like this. So whenever user click on logo button Activity A should be called. As simple solution we can use this method...</p>

<pre><code>Intent intent = new Intent(activity, activityToStart);
startActivity(intent);
</code></pre>

<p>But this activity will create a new activity for my app. but I need to call the same instance of the activity as we move forward in flow diagram. from Activity A to B and then again on B can be called easily by calling<code>finish()</code> but from Activity C or D, how to come back to A. </p>

<p>I am running out of ideas but not getting any fruitful result. Please help me if you have any suggestion or at any place i am going wrong. Thanks in advance.</p>
