If you're asking, "Does the Market support this functionality?"... the
answer is No.

If you're asking "How do I accomplish this in my own code?"... I think
it'd be a manual process. Something like this, for example:

1. When the user clicks the button in Color Meter, log that action
(probably in SharedPreferences)
2. Register a BroadcastReceiver in Color Meter for the
ACTION_PACKAGE_ADDED intent.
3. When received, check to see if the newly-installed package is Super
Camera
4. If it is, log it to a server somewhere
5. Compare the counts on that server to your raw install numbers for
Super Camera

It's quite a long way around the barn, and obviously requires that
Color Meter has Internet permission (which it may not have now). And
there might be an easier way that I'm not seeing right now. But unless
Google dramatically improves the Market data available to devs (we can
hope), I'm thinking this kind of approach is your only option.

Question is, are these stats worth that LOE to you?
