[activity(label = "material", icon = "@drawable/icon", theme = "@style/maintheme", mainlauncher = true, configurationchanges = configchanges.screensize | configchanges.orientation)] public class mainactivity : global::xamarin.forms.platform.android.formsappcompatactivity {     protected override void oncreate(bundle bundle)     {         tablayoutresource = resource.layout.tabbar;         toolbarresource = resource.layout.toolbar;          base.oncreate(bundle);         global::xamarin.forms.forms.init(this, bundle);         loadapplication(new app());     } }

i following this tutorial. thanks!

so far got this... enter image description here

you should wrap contentpage in navigationpage in app.(xaml).cs.

so when defining mainpage inside app.(xaml).cs way:

public app() {     initializecomponent();     mainpage = new navigationpage(new mainpage()); }

when navigating further, not have wrap contentpage in navigationpage each time, navigation relative.
