Story

We, programmers built Apps for people to use, sometimes, we could benefit from our users, too.

Last week, a requirement came to me, that we needed to know how often some kind of actions users did in one of our products.

It's temporal, I didn't want to write a mapreduce program, instead, I figured out an hive SQL which is a little complicated (joins 3 tables and a long where clause).

I have written about how to use iOS and Android Libraries in Cocos2d-x, in mobile game industry, there is another cross platform framework named unity3d, which is more elegant, powerful, and, super expensive!

This post will show how to enable the App using unity3d framework to use native libraries of iOS and Android.

When I began to learn Objective C, I often heard of people talking about "sending message", I was curious, come on, it's just calling a method.

Then I recalled that I had that same feelings when functions become to methods as I began to touch C++.

Been working on some libs on both iOS and Android platforms for a long time, recently needed to support Cocos2d-x framework, I have no interest to write a whole new lib based on C++, nightmare for maintenance, So I worked on to integrate both libs to Cocos2d-x framework.
