Мой Android-приложение зависает, сенсорная кнопка не работает должным образом

/ 21 мая 2019

Я создаю приложение, которое записывает и воспроизводит аудио. Я использую сенсорную кнопку для записи. Звук успешно записывается при длительном касании, но если я коснусь кнопки, не удерживая ее нажатой более одной секунды, мое приложение вылетает. 

    mRecordBtn.setOnTouchListener(new View.OnTouchListener(){
        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
                startRecording();
                mRecordLabel.setText("Recording...");
            }
            else if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                stopRecording();
                mRecordLabel.setText("Recording stopped");
            }
            return false;
        }
    });

    private void startRecording() {
        recorder = new MediaRecorder();
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        recorder.setOutputFile(fileName);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);

        try {
            recorder.prepare();
        } catch (IOException e) {
            Log.e(LOG_TAG, "prepare() failed");
        }
        recorder.start();
    }

    private void stopRecording() {
        recorder.stop();
        recorder.release();
        recorder = null;
    }

    Application terminated.

Я могу сказать, что что-то не так при остановке процесса записи, но я не могу исправить это самостоятельно ...

Подготовка требует некоторого времени для выполнения, поэтому при нажатии вы пытаетесь остановить рекордер, но не уверены, что он уже запущен, вы можете иметь переменную isStarted, чтобы проверить или окружить остановку с помощью попытки. поймать.

 private void startRecording() {
    recorder = new MediaRecorder();
    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    recorder.setOutputFile(fileName);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);

    try {
        recorder.prepare();
    } catch (IOException e) {
        Log.e(LOG_TAG, "prepare() failed");
    }

    recorder.start();
    isStarted = true;
}

private void stopRecording() {
  if(isStarted) {
    recorder.stop();
    recorder.release();
    recorder = null;
    isStarted = false;
  }
}
