This is a followup question. The docs for LocalActivityManager.startActivity() say -
"If the current activity uses a non-multiple launch mode (such as singleTop), or the Intent has the FLAG_ACTIVITY_SINGLE_TOP flag set, then the current activity will remain running and its Activity.onNewIntent() method called. " Two confusions here: (1) singleTop is a multiple (not a non-multiple) launch mode as I understand it. I assume this should read "singleTask" instead of "singleTop". (2) "current activity" apparently means "previous activity with the same id" which might not be the currently running activity returned by the getCurrentActivity() method. I think what the passage means is that if you set singleTop launch mode then it will resume the previous activity rather than recreating it whether or not it is the currently running (top) acrtivity. Otherwise there would not be a way to resume the previous Activity unless it was a non-multiple launch mode. Is that right? On Nov 23, 11:06 am, chentschel <[email protected]> wrote: > Thanks Dianne.
