В чем причина (java.io.IOException: No such file or directory)?

Пытаюсь записать аудио-поток в файл на устройство. Права на чтение/запись файлов в манифесте присутствуют.

<permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

При нажатии по соответствующей кнопке в активити, к которой привязан слушатель, в котором должен сработать метод, я получаю исключение следующего рода:

подаю url-адрес потока в метод в активити (StationActivity):

button_rec.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
        if (Streamer.getInstance().isPlaying()) {
            StationActivity.isRecording = true;
            AudioRecorder audioRecorder = new AudioRecorder(Streamer.getInstance().getStation().getStreams().toString(), StationActivity.context);
            button_rec.setImageResource(R.drawable.admin);
            System.out.println(Streamer.getInstance().getStation().getStreams().toString() + " : " + isRecording);
        } else if (StationActivity.isRecording && Streamer.getInstance().isPlaying()) {
            StationActivity.isRecording = false;
            button_rec.setImageResource(R.drawable.aboutus_menu);
            System.out.println(Streamer.getInstance().getStation().getStreams().toString() + " : " + isRecording);
        }
    }
});
