java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.setDrawingCacheEnabled(boolean)' on a null object reference

Got a crash from one user.
Making a null pointer check will solve this issue I guess in stopDrag(), e.g.

        if (item != null) {
            item.setDrawingCacheEnabled(false);
            item.destroyDrawingCache();

            item.setVisibility(View.VISIBLE);
        }

Android: 5.0.1
Manufacturer: samsung
Model: SM-N915G
