Debugging garbage collection on Android = How to find out what causes the garbage collection

Hi,

I am running my complex application on Android, and whenever I execute a specific UI interaction ( I show an existing display object and move some display object groups around ) I get a massive garbage collection, resulting in a huge delay. Only happens on Android, not on the simulator.

I have other UI interaction that move displayobjects around, but none causes this heavy garbage collection.

Does anyhow have an idea on how I find out which LUA code trigger the garbage collection without littering my code with print statements on every line ?

I am using 2013.1064

Thanks a lot

Frank
