This is due to "task affinities." By default all activities in an .apk have the same task affinity, so that when one is launched it is associated with any current task started via any other activities in the app.
If you publish multiple top-level activities in your app, you will probably want to give them different task affinities so the system does not try to treat them as part of the same logical flow. This is accomplished with the android:taskAffinity attribute in the manifest, as described here: http://developer.android.com/guide/topics/fundamentals.html#afftask <http://developer.android.com/guide/topics/fundamentals.html#afftask>And here: http://developer.android.com/guide/topics/manifest/activity-element.html#aff Another place where it is useful to set the taskAffinity is for an activity that is launched from a notification, so that it will be launched separately from the main application and thus allow the user to press back to return to whatever they were doing instead of having to go back through whatever is on your main task's stack. In this case you would set android:taskAffinity="", saying that activity has no affinity to other activities.
