some more thoughts... What I've said about taskAffinity and launchMode attributes, in general, makes sense when the activities are in the same app since the default value of taskAffinity will be set to the package name. When the activities across apps activate one another, just the launch mode value tells if the launched activity would be the root of the new task. Again, this is because the package names of the apks would be different.
