Hi Filip, As per your suggestion i called finish() in the list body activity the problem which i discussed in the previous to last mail. But then I am facing one problem. Actually I am having an email button in it callling the email intent from there. When I am clicking on email intent and press back button it finishes the list body activity itself.
*Now Required flow is *, 1) when i press directly on list body item activity it should finish it which currently it is doing. 2) When i press email button on the list body item activity it should not finish the list body item activity which currently what it is doing. For problem no. 2 i had even check a flag for this but it never goes into the onkeydown method or onbackpress method when back button is pressed on email intent. Please help. Thanks for your replies.
