You may have noticed that your CrimeFragment has mysteriously lost its margins. In fragment_crime.xml, you specified a margin of 16dp.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="16dp"
    android:orientation="vertical">

That margin no longer shows up. So, what gives? ViewPager’s layout params do not support margins. Update fragment_crime.xml and restore your margins.
