Activity已泄露ServiceConnection android.speech.SpeechRecognizer $ Connection

标签: android speech-recognition google-glass google-gdk

我试图在谷歌眼镜中创建一个功能,允许我在卡片之间导航,而不必说出热门词" ok glass"。

我尝试创建一个SpeechRecognizer,它将持续监听是否正在说某些内容以及是否正确的"命令"正在提及该应用程序将采取相应行动。

然而onError方法告诉我

Error occured: RecognitionService busy.

并且它抛出了一个错误

我目前正在使用这个项目来测试我想在最终应用程序中使用的一些功能。目前我正在使用

这是我为SpeechRecognizer编写的课程

package com.example.sw_stage.topfinder;

import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.os.Bundle;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.util.Log;

import java.util.ArrayList;


public class SpeechDetector {
AudioManager mAudioManager;
SpeechRecognizer mSpeechRecognizer;
Intent intent;
issueKey mIssueKey = new issueKey();

public SpeechDetector(Context context)
{
    Log.i("speechdetector", "calling speech detector");
    mAudioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

    mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(context);
    mSpeechRecognizer.setRecognitionListener(new listener(context));

    intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    Log.i("package name", context.getPackageName());
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, context.getPackageName());
    mSpeechRecognizer.startListening(intent);
    Log.i("111111","11111111"+"in");
}

class listener implements RecognitionListener
{
    Context context1;
    public listener(Context context)
    {
        context1 = context;
    }

    @Override
    public void onReadyForSpeech(Bundle bundle) {

    }

    @Override
    public void onBeginningOfSpeech() {

    }

    @Override
    public void onRmsChanged(float v) {

    }

    @Override
    public void onBufferReceived(byte[] bytes) {

    }

    @Override
    public void onEndOfSpeech() {
        mSpeechRecognizer.startListening(intent);
    }

    @Override
    public void onError(int i) {
        //3 Audio recording error.
        //5 Other client side errors.
        //6 - No speech input
        //7 -No recognition result matched.
        //8 RecognitionService busy.
        //9 - vInsufficient permissions


        if(i == 1 || i == 2 || i == 3 || i == 4 || i == 5 || i == 6 || i == 7 || i == 8 || i == 9)
        {
            Log.wtf("Error occured", "Error " + i);
            mSpeechRecognizer.startListening(intent);
        }
    }

    @Override
    public void onResults(Bundle bundle) {
        ArrayList data = bundle.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
        String result = "enter";
        String reslt = "";
        for (int i = 0; i < data.size(); i++)
        {
            reslt = reslt + " " + data.get(i);
        }
        switch(result)
        {
            case "next":  mIssueKey.issueKey(22);
                break;
            case "previous": mIssueKey.issueKey(21);
                break;
            case "enter": mIssueKey.issueKey(23);
                break;
            case "leave": mIssueKey.issueKey(4);
        }

    }

    @Override
    public void onPartialResults(Bundle bundle) {

    }

    @Override
    public void onEvent(int i, Bundle bundle) {

    }
}

}

我在我的MainActivity onCreate()方法中调用了这个类。

private SpeechDetector mSpeechDetector;

@Override
protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);

    mIssueKey = new issueKey();
    mSpeechDetector = new SpeechDetector(getApplicationContext());

我改变了

new SpeechDetector(MainActivity.this);

new SpeechDetector(getApplicationContext());

再次出现泄露错误

无论其

显然泄露的错误和RecognitionService忙不相关。 因此,我仍然坚持认为我的语音识别无效,因为它会引发RecognitionService busy错误

修改 我只是注意到它写了一个额外的日志

    03-03 13:11:13.252  20018-20018/? A/Error occured﹕ RecognitionService busy
    03-03 13:11:13.260      825-825/? I/RecognitionService﹕ concurrent startListening received - ignoring this call

2 个答案:

答案 0 :(得分:1)

看起来RecognitionService已在您拨打startListening()时使用。我相信这是因为您已在构造函数中调用startListening(),然后在onEndOfSpeech()中再次调用它。

在再次致电cancel()之前,请务必进行必要的startListening()来电。

答案 1 :(得分:0)

由于此代码,您获得RecognitionService busy

@Override
public void onEndOfSpeech() {
    mSpeechRecognizer.startListening(intent);
}

您应该在mSpeechRecognizer.startListening(intent)

中致电onResults
