Can't get transition on Cocos2dxActivity termination

I have an android activity that launches the Cocos2dxActivity and there’s a button in the game scene that ends the scene, and since it’s the only scene on the stack, terminates the Cocos2dxActivity (which is what I want to happen). However, I’m having trouble implementing a fade transition from the cocos scene to the android activity.
The screen just goes black and then after a second or two, my android activity shows up.

I followed the code to exactly what happens and the activity is terminated through Cocos2dxHelper class.

Are there any framework procedures to get this ending transition to work?
Or any known methods or ideas of how to produce this effect?

Thanks.
