why isn't the data from my bundle being sent to the new activity?
<p>For reasons I cannot determine, the name string I am passing to the display activity will not be updated when I change it in the menu setting. I have omitted some excess code but hopefully the concepts are there. In particular, when DisplayName is started, I checked with the debugger and the extras put into the intent do not change from their default values (ie: "John Doe"). I note that when I use the options menu activity to change the name, this change is reflected every time I go back to the options menu. However, when I go to the display screen, the name continues to stay the same.</p>

<p>I am aware that these values are simple enough that they can be kept in static member variables and I wouldn't normally have to deal with the passing of bundles, however I still am curious as to why my code fails to function correctly.</p>

<p>I notice that if I use the menu option to set the name first, then click the display button, the change is reflected. However, after returning to the main screen and changing the name, the display screen continues to keep the same name. This leads me to think that since I press "Back" to return to the main screen from the display activity, then the activity is never killed so it would never change the displayed name. Is this guess correct?</p>
