我試圖在谷歌眼鏡中創建一個功能，允許我在卡片之間進行導航，而無需說出「ok glass」這個熱門詞彙。
我試着創建一個SpeechRecognizer，它會不斷地偵聽是否有人在說什麼，如果提到正確的「命令」，應用程序將會相應地執行。
然而，onError方法告訴我
Error occured: RecognitionService busy.
和它拋出，說
Activity com.example.sw_stage.topfinder.MainActivity has leaked ServiceConnection [email protected] that was originally bound here

我目前使用這個項目來測試一些我想有功能的錯誤我最終申請。目前我使用
- 頭部姿勢導航
- 活卡和浸泡
- 爲了使用shell命令的類simulate touch gestures
這裏組合爲I類寫了SpeechRecognizer
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（）方法中調用這個類。
private SpeechDetector mSpeechDetector;
@Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
mIssueKey = new issueKey();
mSpeechDetector = new SpeechDetector(getApplicationContext());
我改變
new SpeechDetector(MainActivity.this);
到
new SpeechDetector(getApplicationContext());
，我不得到泄露的錯誤了
無論其
顯然泄漏錯誤和RecognitionService忙不相關。 所以我還是堅持了這樣的事實，我的語音識別不起作用，因爲它拋出一個RecognitionService busy錯誤
編輯 我只注意到它寫入附加日誌
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
在你的MainActivity中，你有沒有把你的'SpeechDetector'類實例聲明爲'static'？ – 2015-03-03 10:07:54
@ZygoteInit沒有聲明爲靜態。我只是用SpeechDetector類的聲明和調用更新了我的代碼 – NoSixties 2015-03-03 10:14:36
您是否需要服務始終運行或者僅與活動生命有關，如果它只在活動生命中有效，則停止並取消註冊暫停或停止方法。 – 2015-03-03 11:03:18
