title: Properly skip login activity if already logged in
body: <p>My launcher icon currently starts the login activity. I've stored the logged in status in SharedPreferences. Is there any way to <strong>properly</strong> skip the login activity and go straight to the main activity without <strong>any</strong> UI glitches. All existing solutions involving <code>finish()</code> in <code>onCreate()</code> cause the login activity title to be briefly visible or some other brief blank screen UI glitch.</p>
