Please provide any additional information below.
I add some codes in activity.dispose function, below:

even I comment these codes, my game doesn't work when launching second time, I 
think it may relate to memory issue.

I revert to old revision(maybe trunk 364 or 363,not sure), then this bug has 
gone. I can enter the game again. Hi, Richard, I haven't get any new update for 
several days. If you fix something, would you please commit to the svn. Thank 
you very much
