I don't want to use Flurry, nor Localitics, because I'd like to integrate the reporting system with my own server.
Is there a library, that would do the same thing as flurry, but that would send the logs to my own server?
The Localystics client is open-source, so in theory you could adapt it to your needs, but you'd need to handle the server-side yourself.

I don't know of a comparable open-source client-and-server solution.
