Right way to inflate android.support.v4.app.fragment from xml

Question

Please, help.

Which is right?

Like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <android.support.v4.app.fragment
        android:id="@+id/advertListFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:name="com.myapp.fragment.AdvertListFragment"/>

Or like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <fragment
        android:id="@+id/advertListFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:name="com.myapp.fragment.AdvertListFragment"/>

Without prefix "android.support.v4".

P.s. I haven't more details

Answer 1

Use

<fragment
    ...

inflated in an activity that extends android.support.v4.app.FragmentActivity.

For further details, it's FragmentActivity.onCreateView() that handles the inflation for fragment elements.
