Calling Some activity outside activity group

I Have one activity group. Consists of around six activity A >B >C >D >E > F Its working fine in activity group. With this is use to navigate from one activity to another.

     View view = ConsultationGroup.group.getLocalActivityManager().startActivity("newsdisplay", Home1.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();  
     ConsultationGroup.group.replaceView(view);

Now the problem开发者_运维百科 is:

I need to call activity F from activity E and it should not be in the activity group. Hence i need to call the activity outside the actvivity group. I am using this method.

     Intent  Home1=new Intent(E.this,F.class);
     startActivity(Home1);

But the problem is device back key is not behaving properly when again i am coming back to activity E from F. When i hit 5 times back key then it takes me to Activity A. It should behave like F>E>D>C>B>A

I want to save the activity group state on activity E when going to activity F and when coming back it should behave normal when pressing back key.

Pls solve it..

You might need to post a little more code. Where have you put this code?

 Intent  Home1=new Intent(E.this,F.class);
 startActivity(Home1);

i.e. in which lifecycle method?
