The report only provides a stack trace ending in android.support.v4.view.ViewPager.onInterceptTouchEvent at ViewPager.java:2064. Start by tracing that entry point and determining the touch sequence that produces the invalid pointer index; done means the crash is reproducibly prevented, but the issue gives no test or reproduction details.

Written by the indexing model from the issue text.
