android - Some strings are not translated when changing system language without restarting app -

i'm having problem if open android app , go system settings change language , open app again, strings in app won't translated unless app force quit , relaunched. idea why happens? don't have android:configchanges set "locale" anywhere in androidmanifest, doesn't mean activities should restarted on own?

i had issue.i used code below posted in stackoverflow answer , changed language without refreshing activity

public void setlocale(string lang) {      mylocale = new locale(lang);     resources res = getresources();     displaymetrics dm = res.getdisplaymetrics();     configuration conf = res.getconfiguration();     conf.locale = mylocale;     res.updateconfiguration(conf, dm);     onconfigurationchanged(conf);  }  @override public void onconfigurationchanged(configuration newconfig) {     // refresh views here     lbllang.settext(r.string.langselection);     super.onconfigurationchanged(newconfig); } 

i hope you.......
