XML : Including Package In Fragment Widget .XML

I'm adding a fragment called ZipInputFragment within the XML file of one of my activity's.

      <fragment      android:id="@+id/zipCodeFragment"      android:layout_gravity="center_horizontal"      android:layout_width="match_parent"      android:layout_height="wrap_content"      class="com.markf.application.ZipInputFragment"      tools:layout="@layout/fragment_zip_input" />    

This runs fine. The issue is that I have a separate package called non_activity where all of my fragments are stored. So when I place the ZipInputFragment in this package, my application crashes. I know that it's because of this line of code in my widget:

  class="com.markf.application.ZipInputFragment"    

The issue is that it's not acknowledging the fact that my Fragment is now in a separate package. Does anyone the syntax that would include my non_activity package in the widget? Thank you.
