The /res/layout/fragment_item_detail.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    <!-- I actually got it to work by deleting the second block and replacing "TextView" with
    "ImageView"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/item_detail"
    style="?android:attr/textAppearanceLarge"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    android:textIsSelectable="true"
    tools:context=".ItemDetailFragment" />

<!--  The following line complains -->
<ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/android" />
