Android NullPointerException only in Galaxy SII/III phones

Android NullPointerException only in Galaxy SII/III phones

In my app, users select from a ListView and it plays a song based on the
position. Galaxy SII\SIII phones are throwing NullPointerExceptions when
the user tries to select a song. I set the activity to keep the portrait
orientation, and have one main layout(activity_main.xml).
Crash Report:
