How is the "Active Installs" count/percentage in the Android "Developer Console" calculated?
<p>The Android Market Developer Console shows two numbers for your submitted application; "total" and "active installs".  What exactly does the "active installs" number mean?  Is it affected by application upgrades?  </p>

<p>For example:</p>

<ol>
<li>500 users install v1.0 of an app</li>
<li>v2.0 of the app is released and all 500 people upgrade via the Market.</li>
<li>Assume no one uninstalls.</li>
</ol>

<p>Does that yield a "total" of 1000 because the APK was downloaded 1000 times...but an "Active Installs" of 500 (50%) because, in the end, only 500 people are running the app? Does an upgrade get counted as an uninstall followed by an install?</p>
