I know this may be a dumb question, but my background is more in c++ and managing my own memory.

I am currently cutting down every single allocation that I can from one of my games to try and reduce the frequency of garbage collection and perceived "lag", so for every variable that I create that is an Object (String and Rect for example) I am making sure that I create it before hand in my constructor and not create temporary variables in simple 10 line functions... (I hope that makes sense)

Anyways I was working though it some more tonight and I realized that I may be completely wrong about my assumption on garbage collection and primitive types (int, boolean, float) are these primitive type variables that I create in a 10 line function that gets called 20 times a second adding to my problem of garbage collection?

So a year ago every few seconds I would see a message in logcat like

GC freed 4010 objects / 484064 bytes in 101ms

Now I see that message every 15-90 seconds or so...

So to rephrase my question: Are primitive types (int, float, boolean, etc) included when seeing this message?
