Question

menu item is not appearing in action bar. I am trying this code on API 19, kitkat 4.4 using this XML code.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:title="Sign out"
        android:id="@+id/iSignout"
        android:icon="@drawable/signout"
        android:orderInCategory="100"
        android:showAsAction="always"/>
    <item
        android:title="My Profile"
        android:id="@+id/iEditProfile"/>
    <item
        android:title="Edit Profile"
        android:id="@+id/iMyProfile"/>
</menu>

and

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.action_bar_menu, menu);
        return true;
    }

Try this:

        android:id="@+id/iSignout"
        android:icon="@drawable/signout"
        android:orderInCategory="100"
        app:showAsAction="always"/>
    <item
        android:title="My Profile"
        android:id="@+id/iEditProfile"/>
    <item
