Android app Icons are not displayed in the menu, why?

Question

Android

I ask for help from experienced android application developers. I'm trying to make a menu with icons, but it doesn't work - the icons are not displayed.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_bookmark"
        android:icon="@drawable/ic_launcher"
        android:title="Bookmark" />

    <item android:id="@+id/menu_save"
        android:icon="@drawable/oplata"
        android:title="Save" />

    <item android:id="@+id/menu_search"
        android:icon="@drawable/abc_btn_check_material"
        android:title="Search" />

    <item android:id="@+id/menu_share"
        android:icon="@drawable/ic_launcher"
        android:title="Share" />

    <item android:id="@+id/menu_delete"
        android:icon="@drawable/ic_launcher"
        android:title="Delete" />

    <item android:id="@+id/menu_preferences"
        android:icon="@drawable/ic_launcher"
        android:title="Preferences" />
</menu>

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        menu.add(0, 0, 0, "androidDemo").setIcon(R.drawable.ic_launcher);
        getMenuInflater().inflate(R.menu.newmenu, menu);

I click on the menu call and I do not see the icons. The lessons say that they should already be, help me figure it out.
