i have checked

startactivityforresult();

but dont have clear if way it, , have not make work

so how trigger function when user comes email intent?

thanks

start activity startactivityforresult(); , override following method

@override protected void onactivityresult(int requestcode, int resultcode, intent data) {     // todo auto-generated method stub     super.onactivityresult(requestcode, resultcode, data);             //place code here want when result returned, in  case go different activity } 

this method invoked when called activity returns result
