我正在为我的 android 应用程序使用 CMU Flite TTS 引擎。我已经使用引擎名称初始化了 android TTS 对象，并且还在 onDestroy 中调用了它的 shupdown 方法，但我仍然收到服务连接泄漏错误。

请任何人告诉我我错在哪里。这是我的代码

protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    mProgressDialog = new ProgressDialog(this);
    mMediaPlayer = new MediaPlayer();
    mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    mProgressDialog.setMessage("Please wait ...");

    usertext = (EditText) findViewById(R.id.editText);
    play = (Button) findViewById(R.id.button);
    voiceempty = engine.initialize_engine(getApplicationContext());
    Toast.makeText(this,"Engine initialized",Toast.LENGTH_SHORT).show();
    if (voiceempty) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage("Flite voices not installed. Please add voices in order to run the application");
        builder.setNegativeButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.cancel();
                Intent intent = new Intent(Intent.ACTION_MAIN);
                intent.setComponent(new ComponentName("edu.cmu.cs.speech.tts.flite", "edu.cmu.cs.speech.tts.flite.DownloadVoiceData"));
                startActivity(intent);
                finish();
            }
        });
        AlertDialog alert = builder.create();
        alert.show();
    } else {
        // Initialize the TTS
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            mTts = new TextToSpeech(this, this, "edu.cmu.cs.speech.tts.flite");
        } else {
            mTts = new TextToSpeech(this, this);
        }
    }
}

onDestroy 方法的代码是

@Override
public void onDestroy()
{
    super.onDestroy();
    mTts.stop();
    mTts.shutdown();
    mMediaPlayer.stop();
    mMediaPlayer.release();
    String fileName = Environment.getExternalStorageDirectory().getAbsolutePath() + FILENAME;
    File file = new File(fileName);
    if(file.exists())
    {
        file.delete();
        Log.d("File_delete",fileName+" file deleted successfully");
    }
}

我什至在 onBackPressed 方法中尝试过这个，但仍然得到同样的错误。

我猜你在 TTS 系统有时间加载之前关闭/停止应用程序太快了。在按下返回按钮之前尝试稍等片刻，看看错误是否仍然发生。

我也有同样的问题。据我所知，没有办法解决它。但它没有任何后果，所以我选择忽略它。

如果你找到一个好的解决方案，请告诉我。

此外，作为旁注，您应该：

tts = new TextToSpeech(context, new TextToSpeech.OnInitListener() {
    @Override
    public void onInit(int status) {
        if (status == TextToSpeech.SUCCESS){
            int langResult = copilot.setLanguage(language);

            if (langResult == TextToSpeech.LANG_MISSING_DATA
                || langResult == TextToSpeech.LANG_NOT_SUPPORTED) {
                Log.e(TAG, "ERROR: Text to speech language is not supported");

            } else {

            // code here

            Log.w(TAG, "...Text to Speech ready!");
            }

        }else{
            Log.e(TAG, "ERROR: Text to Speech initialization failed");
        }
    }
});
