Here is some more research on this:
quick summary once again: I have two activities
1. main
2. search activity
Nature of search activity
****************************
1. invoke a browser
2. finish after that
3. As a result browser will be showing when this search activity is invoked
When does it work
************************
If I have never invoked the MAIN activity of this application then the
back button on the invoked browser activity will take me back to where
I came from. (home)
when does it NOT work
******************************
If I invoked the MAIN activity at any time prior to the global search,
then the back button on the browser will take me quite disconcertingly
I should say to the MAIN activity irrespective of how far back in the
history it is.
The behavior seem un changed even if I set the
android:allowTaskReparenting="false"
What alternative I have
****************************
In my case the MAIN activity happens to be spurious and unnecessary
and I had it just for debugging. I had to remove this activity from
the application to make this work reliably
Hope these notes would be of some help if you were to stray this way.
well anyways if you have some ideas I would love to hear them
Thanks
