After using "dumpsys activity" extensively to determine what is happening to the task activity stack, I have determined that when I add FLAG_ACTIVITY_NEW_TASK as a flag on my Intent used to switch between the two tasks in my application, Android is adding another activity to the stack, instead of just resuming the task in it's prior state.
For example, if I'm in Task B, and I want to switch to Task A, I do: Intent i = new Intent(context, RootActivityA.class); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); The documentation leads me to believe that Android is supposed to simply resume Task "A" (where RootActivityA is the root of Task A), and bring me back to where I left off (which was an Activity deeper in the stack in A, NOT RootActivityA). But instead what's happening is that it's adding another RootActivityA to the stack, i.e. RootActivityA-->Activity A1 --> Activity A2 --> RootActivityA This is not what I am expecting, considering this is the documentation for FLAG_ACTIVITY_NEW_TASK: "When using this flag, if a task is already running for the activity you are now starting, then a new activity will not be started; instead, the current task will simply be brought to the front of the screen with the state it was last in. See FLAG_ACTIVITY_MULTIPLE_TASK for a flag to disable this behavior." Does anyone have any idea why Android would be adding another copy of RootActivityA onto the history stack instead of just resuming the Task at the last place it left off? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
