在模拟器和真实设备上都使用语音识别时，尽管清单明显，但“未连接网络”

Question

我正在尝试使用Android Studio进行语音识别。

我正在使用this website中的教程。

我知道语音识别的一些典型问题，所以我再次检查了这一点：

1. 我的清单文件包含其他权限。
2. 网络可在模拟器上运行。
3. 测试语音识别器是否可用-已通过模​​拟器。

我已经在模拟器（Nexus 5X API 28 x86）上对其进行了测试。

语音识别显示“网络未连接”（这是不正确的）：

我的清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mei.chat">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.BLUETOOTH" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name="com.example.mei.chat.SimpleVoiceRecognition"
        android:label="@string/title_activity_simple_voice_recognition"
        android:theme="@style/AppTheme.NoActionBar"></activity>
    <activity android:name="com.example.mei.chat.MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

我的MainActivity文件：

package com.example.mei.chat;

import android.app.Activity;
import android.content.Intent;
import android.speech.RecognizerIntent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import java.util.List;

public class MainActivity extends Activity {

private final int REQUEST_SPEECH_RECOGNIZER = 3000;
//private TextView mTextView;
private final String mQuestion = "Which company is the largest online retailer on the planet?";
private String mAnswer = "";

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

    setContentView(R.layout.activity_main);
   // mTextView = (TextView)findViewById(R.id.tvstt);

    startSpeechRecognizer();
}

private void startSpeechRecognizer() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, mQuestion);
    startActivityForResult(intent, REQUEST_SPEECH_RECOGNIZER);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == REQUEST_SPEECH_RECOGNIZER) {
        if (resultCode == RESULT_OK) {
            List<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            mAnswer = results.get(0);
            ...
        }
    }
}
}

运行日志看起来很干净（唯一的“错误”似乎是有关GPU加速的信息，我认为它们是无害的-“ E / eglCodecCommon”）：

要测试语音识别器在模拟器上是否可用，我使用了以下代码：

PackageManager pm = getPackageManager();
List activities = pm.queryIntentActivities(new Intent(
    RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() == 0) {
    Toast.makeText(this, "Voice recognizer is not available in your device", Toast.LENGTH_SHORT).show();
}else{
    Toast.makeText(this, "OK. Voice recognizer is available.", Toast.LENGTH_SHORT).show();
}
