In one of my sample I have three activities: A->B->C , where B has android:launchMode="singleInstance" in manifest. Activity A and C has default launch mode. Scenario: After navigating to C via A and B (i.e A->B->C), back button press from Activity C takes to Activity A (C->A), but back button press from Activity A does not quit the app, rather brings the Activity B to front, then back button press from Activity B quits the app. Question Why does

Activity stack keeps a navigation history of activities, and Task is a sequence of activities. Is this is only difference that Activity stack made up of one or more task(S)? Give some example please. 回答1: Activities and Tasks As noted earlier, one activity can start another, including one defined in a different application. Suppose, for example, that you'd like to let users display a street map of some location.

Setup is I have a home activity (subclass of support ActionBarActivity ). The home activity checks a boolean flag, and if true, launches a splash screen activity (yes, ideally the splash comes before the home activity, but let's assume I can't change it to work that way for now). The splash screen is launched with startActivityForResult , it downloads some config options from the server, then finishes and returns the result back to the home

Typical example is an AsyncTask that fetches something from the web and displays the result. There are 2 problems with this: The AsyncTask has a reference to Activity (because it needs to update its UI). After screen orientation change, the Activity is restarted. But the AsyncTask still references to the old destroyed Activity therefore it can't update the UI of the new Activity. This can lead to OutOfMemoryException

Is there any way to properly skip the login activity and go straight to the main activity without any UI glitches. All existing solutions involving finish() in onCreate() cause the login activity title to be briefly visible or some other brief blank screen UI glitch. 回答1: Have a launcher acitivy with no UI that decides to open the MainActivity or the LoginActivity. You can declare no UI with: android:theme="@android:style/Theme

For that I decided to add an activity indicator. I wrote a little function: func showActivityIndicator () { dispatch_async ( dispatch_get_main_queue ()) { self . spinner = UIActivityIndicatorView ( activityIndicatorStyle : .

The service sends a broadcast that will let the application start Activity B Now the user starts activity C. Now the service wants to start activity B again. But how do I let him know that the activity is still on the stack, or is there an intent flag for this? How do I avoid that it will launch activity B because its already in the stack? 回答1: I think you need to make your activity B singleInstance that if it's already create you
