Try to use <fragment android:name="" instead of class as this post — TuyenNTA

Change this file: list_fragment.xml

    <ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

Your Fragment extends from ListFragement. It implies that your fragment layout must have ListView with id android.R.id.list (Previously it was just a FrameLayout) so now it becomes a ListFragment. Android need to call functions on it so it needs a proper id on the listview which is by default android.R.id.list
