android - Slow startup of second activity -


what should when settings activity starting slow? anr keydispatch error if takes long.

should using preferenceactivity. absolute first time go settings delay time slow (about 5-10 seconds), otherwise goes super smooth. appear when i'm reinstalling application , start settings first time (so it's first time thing).

some code in settings preferenceactivity:

@override protected void oncreate(bundle icicle) {     super.oncreate(icicle);      pref = getpreferencemanager();          pref.setsharedpreferencesname(livewallpaper.preferences);     addpreferencesfromresource(r.xml.live);     pref.getsharedpreferences().registeronsharedpreferencechangelistener(this);      pref.findpreference("username").setonpreferenceclicklistener(new onpreferenceclicklistener() {                   public boolean onpreferenceclick(preference preference) {                                           // stuff...                 return true;                             }         }     ); // , on...

basically, want find out error located, question how? can see in logcat that's causing delay?

thanks answer!
