Android : How to track some basic values for each user in Flurry Analytics?

Does anyone have any experience using Flurry Analytics? I have some problems. Let me start from example:

Lets imagine a typical mobile messenger app. I want to get segmentation of users by their contacts list size. Something about this:

• 0 - 5 contacts = 35% of all users


• 6 - 10 contacts = 50% of all users


• 10 - 20 contacts = 10% of all users


• 20+ contacts = 5% of all users

That will be nice if I could use some additional parameters, like user age or gender (or some another segmentation made in this way), to track this stats.

But I have no idea how to implement this via Flurry custom events, and events parameters!

I understand how to track % of users that hit some event ("App_Tutorial_Finished" for example). Just go to "Custom Segments" and create new with:

Users that have triggered ALL of these events:

• Event: App_Tutorial_Finished

But what if we need to track some user parameter that changes somehow threw the usage of application? Examples: error counts for each user, user facebook friends count, some current parameters in app that user selected...
