Android "；“网络未连接”；在模拟器和真实设备上使用语音识别时

我正在尝试使用Android Studio进行语音识别工作

我正在使用来自的教程

我意识到语音识别的一些典型问题，因此我再次检查：

我的清单文件包含其他权限

网络在仿真器上工作

测试语音识别器是否可用-通过

我已经在emulator（Nexus 5X API 28 x86）上测试了它

语音识别显示“网络未连接”（事实并非如此）：

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>

为了测试emulator上的语音识别器是否可用，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();
}

识别器需要一个到谷歌服务器的Intellet连接。不管出于什么原因，你都没有。识别器需要一个到谷歌服务器的Intellet连接。不管什么原因，你都没有。
