什么是Storage/Emulated/O？
这是我保存音频文件的函数：

private void synthesizeTextToAudioFile(String textToSpeak) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
       
        String destDirectory = Environment.getExternalStorageDirectory().getAbsolutePath();
        File directory = new File(destDirectory);
        if (!directory.exists()) {
            directory.mkdirs(); =
        }

        // Create a unique file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
        String audioFileName = "audio_" + timeStamp + ".mp3";
        File outputFile = new File(directory, audioFileName);

        // Synthesize text to an audio file
        speech.synthesizeToFile(textToSpeak, null, outputFile, "uniqueID");

        // Display a message with the file location
        Toast.makeText(getContext(), "Audio File Saved at: " + outputFile.getAbsolutePath(), Toast.LENGTH_LONG).show();
    } else {
        Log.e(TAG, "Synthesizing to file is not supported on this device");
       
    }
}

字符串
我试图在谷歌文件中找到该文件，但我无法.它说该文件是保存在storage/emulsified/0，但在哪里？有没有一种方法，我可以直接在sdCard中创建一个文件夹，然后能够在谷歌文件上打开它？
