Как отлаживать методы типа onListener, такие как onTouch или onOptionsItemSelected?

Question

Я пытаюсь отладить две части моего кода, одну из которых составляют обратные вызовы (onOptionsItemSelected), которые вызываются, когда пользователь выбирает выпадающее меню, вызывает сбой приложения, а другая (onTouch) не работает должным образом.

Очевидно, что мой первый ответ состоял в том, чтобы отладить и посмотреть, что происходит, но хотя я установил контрольные точки во всех местах, которые я хочу исследовать, отладчик на этом не останавливается.

Опять же, для ясности, методы, которые я хочу отлаживать, это метод onTouch и onOptionsItemSelected. Остальная часть кода здесь должна быть максимально подробной.

Кто-нибудь может помочь?
