Android history only for 1 activity
<p>I would like to know if it's possible to keep only 1 of each activity in history? I have tab-like interface and when user goes between activities it remembers them in history.</p>

<p>I tried noHistory attribute but it will cause activities to not go into history at all.
Ideally I'd like to have history but make it work like this:</p>

<p>Scenario:
Act1->Act2->Act1->Act2</p>

<p>In "standard" setup when clicking "back" it will unwind like
Act1->Act2->Act1->GONE</p>

<p>In "noHistory" mode it when click "back" it will be:
GONE</p>

<p>I want only 1 copy of each in stack, so it will be:
Act1->GONE</p>

<p>Possible?</p>
