我正在

java.io.FileNotFoundException: Is a directory

尝试将tts合成到文件时出现

错误（来自语音识别和文本输入）当使用4.1.2操作系统在Android设备上进行测试时，它会将音频文件放在根目录而不是文件夹I＆＃39 ; m告诉它使文件进入，然后崩溃与该错误，它在根目录中创建的文件的名称是：

K9 Remotespoken.wav //when it should be saved as: K9 Remote/spoken.wav

但是，当我用我的其他设备测试android 7.0 os时，它不会崩溃或给出错误，但它根本不会制作音频文件，我做错了什么？

有人可以解释为什么以及如何在函数synthesizeToFile（＆＃34; theText＆＃34;，bundle，file，string）中为lolipop和up synthesizeToFile函数获取第4个参数？我知道前3个是什么以及它们做了什么，但android开发者文档只说第4个参数中的字符串是唯一标识符？请解释一下，谢谢

private String state;
private File Root;
public File myFilename; //used in lolipop +
public String msg; //used in pre lolipop

//ON CREATE EVENT
    if (Environment.MEDIA_MOUNTED.equals(state)) {
        Root = Environment.getExternalStorageDirectory();
        myFilename = new File(Root.getAbsolutePath() + "/K9 Remote");
        if (!myFilename.exists()) {
            myFilename.mkdirs();
            msg = myFilename.toString();
        }
    }

    //REST OF RELEVANT CODE
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 400) {
        if (resultCode == RESULT_OK) {
            ArrayList<String> res = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            String holdForGMS = String.valueOf(res.get(0));
            HDC = appPreferences.getInt("h_d_c", 0);
            float nPitch = appPreferences.getFloat("my_pitch", (float) 1.0);
            float nSpeed = appPreferences.getFloat("my_speed", (float) 1.0);
            tts.setSpeechRate(nSpeed);
            tts.setPitch(nPitch);
                if (HDC == 0) {
                    if (transmitter == 1 && remote == 0) {
                        speakIT(holdForGMS);
                    }
                    if (transmitter == 1 && remote == 1) {
                        sendIT(holdForGMS);
                    }
                }
                if (HDC > 0)
                    synthToFile(holdForGMS);
            }
        }
    } 

 public void synthToFile(String ultraSynth) {

    try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {//THIS IS PRODUCING THE ERROR
            this.tts.synthesizeToFile(ultraSynth, null, myFilename,"/spoken.wav");
            PitchPlayer();
        }else
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {//I DO NOT HAVE A DEVICE WITH THIS OS TO EVEN TEST IF THIS CODE IS WORKING 
            this.tts.synthesizeToFile(ultraSynth, null, msg+"/spoken.wav");
            PitchPlayer();
        }
        } catch
                (NullPointerException e) {
            Log.i("K9 Remote", "Failed, can't synthesize to file");
        }
    }

synthesizeToFile给出java.io.FileNotFoundException：是一个目录错误
