Choose initial scene from java

cocos2d-x C++
#1

I have two activity classes that extent Cocos2dxActivity. The activity is started based on user input. These two activities must each start different cocos2dx scene. So, basically, I need to decide what the initial scene will be from android java code. What is the least painful way to do this?

#2

Initial scene selected at AppDelegate, so pass parameter to this class somehow, or store parameter at java until AppDelegate will take it manually.
