I have a "base" group of activities. Let's call them A1, A2, and A3. When the user switches between these activities, they are at the "bottom" of the app. When they press the BACK button in either A1, A2 , or A3, they leave the app (or task).
An easy way to visualize this is a tab activity, such as the phone app. When you switch tabs in the phone app, the individual activities are not finished. This is important because if you scroll down in your call log, and then change tabs to your contacts, and then return to the call log, the activity is still in the same state, with the list being scrolled down. I am trying to find a way to mimic this behavior, but without the use of a TabActivity. The problem I've run into is that when you use the various task and intent flags such as FLAG_ACTIVITY_SINGLE_TOP, FLAG_ACTIVITY_NEW_TASK, and/or FLAG_ACTIVITY_CLEAR_TOP, is that you can mimic the navigational functionality, but the other tasks are finished() and destroyed when you switch. This is not optimal; when switching back and forth between the tabs/activities, there is no good reason to destroy and re-create the activities. (In the above example, the call log wouldn't be scrolled down to the same spot because it was destroyed and recreated) I would love to find a simple flag such as FLAG_CLEAR_TASK_STACK. That's all I need, although it doesn't exist from what I can tell. I wonder if the only way to accomplish this is to do what TabActivities do themselves and create my own ActivityGroup? I'm sure that would solve the problem, but it seems to be overkill to just solve this problem.
