Hello
i'm doing an app and i have included this code
http://developer.android.com/training/contacts-provider/retrieve-names.html
but i have a problem...on kitkat it works well, in lollipop i can't see the
menu toolbar and when i click on a contact the app crashes with a
nullpointerexception
*void.android.app.actionbar.setdisplayhomeasupenabled(boolean) etc*
in this portion of code:
if (Utils.hasHoneycomb()) {
// Enables action bar "up" navigation
getActionBar().setDisplayHomeAsUpEnabled(true);
}
how can i resolve this??
thanks for all
