Запуск SpeechRecognizer из JobService

Question

Я пытаюсь создать приложение для своего проекта в колледже, которое использует планировщик заданий для записи звука в фоновом режиме с микрофона устройства в течение 5 секунд каждые 15 минут с помощью SpeechRecognizer. Я пробовал следовать нескольким учебникам, но не могу заставить приложение работать.

В настоящее время у меня есть очень базовое c приложение, в котором есть кнопка, которая будет планировать задачу. Я не уверен, что есть ли лучший способ сделать это, но это был самый дальний уровень, который я смог получить с моим уровнем мастерства в студии android. Мне действительно нужна помощь. Я добавил свой код для приложения, а также ошибки, которые я получаю при запуске приложения.
