"FLAG_ACTIVITY_CLEAR_TOP - If set, and the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent. "
Sadly this one doesn't help since it only clears the stack if the launched activity is already running in the task somewhere (and that's not the case here, sadly :( ) Tauno On Tue, Sep 22, 2009 at 12:17 PM, Andrei Bucur <andrei.bu...@gmail.com> wrote: > http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_CLEAR_TOP > > On Tue, Sep 22, 2009 at 11:26 AM, tauntz <tau...@gmail.com> wrote: >> >> Hi >> >> Activities: >> A & B are activities that once you have navigated away from them, >> it's not logical that you can get back to them using the back button. >> C ...
