Android アプリで次のコマンドに問題があります。
((android.support.v4.view.ViewPager.OnPageChangeListener)mSmallFragments.get(j)).onPageSelected(j);
私は得る：

mSmallFragments = new ArrayList();
問題は、アプリがスマートフォン (4.1.2) では完全に動作するが、タブレット (4.1.1) ではクラッシュすることです。
削除すると: ((android.support.v4.view.ViewPager.OnPageChangeListener)mSmallFragments.get(j)).onPageSelected(j);、
アプリは起動しますが、ArrayList は表示されません (アプリのメイン レイアウトのみ)。
