By the limited information you're giving, it looks like you're having the same problem addressed in this post.

Answer 3

Try this:

 <fragment
    android:id="@+id/frag"
    android:name="com.example.frag.MyFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:layout="@layout/frag_layout" />

you must use android:name="fully qualified path". you have used class="".
