У меня есть эта странная ошибка, когда какой-то мой код не вызывается, но не смотрит, есть ли причина, почему он не будет вызван.
onFinishedRecording
вызывается, и тег "Finished recording."
выходит из системы, но код после этого вообще не вызывается. Весь код перестает вызываться, когда вызывается mMediaRecorder.stop();
. Он также не входит в блок catch. Почему это происходит?
Я думал, что это может быть связано с разными потоками, но я проверил все имена потоков, и все они работают в одном и том же главном потоке.
Кроме того, может быть что-то не так с настройкой предварительного просмотра камеры? Когда я пытаюсь воспроизвести видео, он поврежден и не может воспроизводиться.
В дополнение к вышеуказанным проблемам, моя кнопка назад ничего не делает в приложении. Не совсем понятно, почему и как это связано с кодом, который я реализовал.
