I've already tried that, it doesn't. And to answer my question:
1 - There is a new Intent flag in API 11, FLAG_ACTIVITY_CLEAR_TASK, which does just what I need, clears the existing task before launching the activity as its root. Too bad I can't use that. 2 - Again in API 11, there is a whole new way of launching the application into the middle of its activity stack with PendingIntent, specifically built for use with widgets and status bar notifications. This is actually my case: the reason B ever exists all by itself in the task stack is because it was launched from a widget / status bar, and I'd prefer to launch A and B both in this case. -- Kostya 2011/6/17 Yong Ma <[email protected]> > > Set B's finishOnTaskLaunch true.
