Google Analytics tracker
<p>I have an application, in which I set a tracker. I use <code>tracker = GoogleAnalyticsTracker.getInstance();</code> and <code>tracker.startNewSession("&lt;UA number", this);</code> in<code>onCreate()</code> in every activity. What I'm interested in - is it efficient to start new session in every separate activity or I can do that in my custom activity manager? In the second case I'm not actually sure where to stop the session? Currently I do this in every activity in onDestroy().   </p>
