What is the difference between total installs and active installs in the Android market?

Question

What is the difference between total installs and active installs?

I have 90 total installs for my app and only 47 active installs. What does it mean?

Answer 1

Sometimes i think that it may be something different. For example my app has only 5 days being published...it's just a normal app(with no advertisement or promotion by me) so as anyone can understand only few friends of mine have downloaded it! So I have 4 total installs and only 1 active, still as I saw for myself my friends haven't uninstalled the app(4 of my friends downloaded). They have just downloaded it and used it for a couple of times. So i might be wrong, but my experience showed me that they just don't differ only between installations and uninstallations but between something else. Or what can I say they might hesitate to publish the totals :)
