have a settings dialog/activity where I allow the user to change the locale. Within that activity i call

 Resources res = ctx.getResources(); 
// Change locale settings on the device 
DisplayMetrics dm = res.getDisplayMetrics(); 
android.content.res.Configuration conf = res.getConfiguration(); 
conf.locale = new Locale(language_code.toLowerCase(), 
coutry_code.toUpperCase()); 
res.updateConfiguration(conf, dm); 

and call onChanged() for my settings ListView... everything changes perfectly. Very nice. Then I hit the back button to go back to the previous activity thinking everything should be switched; nope. Everything is still in the previous locale. So I added the above code in the onResume() of the activity thinking that would do it; nope. Also, when I click the menu button of this activity again (not first time) I do not get called in onCreateOptionsMenu() it just displays the previous menu. My question is what is the correct way to force existing activities to reload using the new local?
