Hi All,
Thanks for your replies:
*Problem Detail*:
I am having an activity containing next and previous button. On clicking
next and previous button I am calling the same activity itself but with
different content.
Now, If I am calling this activity by startActivity() in onResume() method,
the problem what coming is that if I click on back button (Phone) it goes to
the onResume method of this activity and calling this activity again. So,
everytime I am pressing back button, it is calling the same activity itself
and never goes back to the home screen.
The same problem is occurring with on key back method.
I am not sure how to do this. I tried various Intent flags also but of no
use for e.g. FLAG_ACTIVITY_CLEAR_TOP, FLAG_ACTIVITY_SINGLE_TOP and
FLAG_ACTIVITY_NO_HISTORY
Any help in this regard would be highly appreciated as I need this on urgent
basis.
Thanks!!
