TabActivity, nested Activities in Tabs and onActivityResult

I have main TabActivity in my project which contains nested activities in each tab. In nested activity i call standart camera application with startActivityForResult() and try to handle开发者_运维百科 result of call by onActivityResult() method. I was expecting that onActivityResult will be executed after camera application finishing, but it called before. What to do in this situation? How to handle camera results?
