[android-developers] Re: Main Activity Launches On Stack Every Time Home Screen Icon Is Clicked
A couple of things to keep in mind:
First, launcher icons are simply shortcuts to intents, and these intents
point to specific activities, not to your app as a whole. In the case of
your main launcher icon, the one in the app drawer, the target activity is
the one in your manifest with this intent filter:
intent-filter
action android:name=android.intent.action.MAIN /
category android:name=android.intent.category.LAUNCHER /
/intent-filter
In your case, I'm guessing that's the LoginActivity. What you probably need
to do is insert a check in its onCreate() method to reopen the
BrowseActivity if the user's already logged in. Something like:
if (loggedIn) {
startActivity(new Intent(this, BrowseActivity.class));
finish();
}
It may seem like a huge hack, but it's not really, not in the context of
launcher intent shortcuts.
Second, keep in mind that the activity *stack* is exactly that - a stack of
the recently-opened activities in your app. By default, opening an activity
simply adds it to that stack, on top of whatever was already there. If you
want different behavior, look at the stack-control intent flags (
http://developer.android.com/guide/topics/fundamentals/tasks-and-back-stack.html
).

Check out my answer (kaciula user) on this issue on stackoverflow.com: http://stackoverflow.com/questions/3042420/home-key-press-behaviour/4782423#4782423 I've filed a bug on b.android.com a couple of months ago but the bug report is still unnoticed. On Apr 9, 9:14 am, Tony Chuinard tony.chuin...@gmail.com wrote: My application consists of a LoginActivity followed by a BrowseActivity. When the user hits the Browse Activity, then hits the Home button, then hits the application icon again, the LoginActivity relaunches (but they're already logged in and in the browse activity so they should be there). However, if I hit back, the BrowseActivity is still there, and the LoginActivity is revisible when I hit back twice. It seems like the LoginActivity gets pushed to the top of the stack and displayed every time the application is launched, but the docs say that the last activity from that 'task' will be launched (which is what I want - a return to the BrowseActivity). I have a static LoginManager class, so I could check if that data is null or not in LoginActivity onCreate() and do a finish() if necessary, but I feel like that's a huge hack when my application should be behaving like this already. -- You received this message because you are subscribed to the Google Groups Android Developers group.
