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
).
