Разрешение доступа микрофона (разрешение) в WebView [Android Studio] [Java]

Question

В настоящее время я работаю над музыкальным тюнером, который использует html5 и веб-просмотр для отображения «приложения». Я написал все разрешения, необходимые в манифесте, и я думаю, что для веб-просмотра требуется другое разрешение.

Я использую этот https://jbergknoff.github.io/guitar-tuner/ как страницу редиректа образца на текущий

Вот мой manifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.raynordev.projectrosin"> 

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.MICROPHONE" /> 
<uses-permission android:name="android.permission.RECORD_AUDIO" /> 
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-feature android:name="android.hardware.audio.low_latency" /> 
<uses-feature android:name="android.hardware.audio.pro" /> 
<uses-feature android:name="android.hardware.microphone" android:required="true"/> 


<application 
    android:allowBackup="true"

    </activity> 
    <activity android:name="com.raynordev.projectrosin.HomeActivity">   

    </activity> 
</application> 
</manifest> 

Вот мой .java

public class HomeActivity extends AppCompatActivity { 

private WebView wv; 
private String TAG = "HomeActivity"; 
private static final int REQUEST_INTERNET = 200; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_home); 
    WebView wv = (WebView) findViewById(R.id.webView); 
    wv.getSettings().setJavaScriptEnabled(true); 
    wv.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); 


    wv.setWebViewClient(new WebViewClient()); 
    wv.setWebChromeClient(new WebChromeClient()); 

    wv.loadUrl("https://jbergknoff.github.io/guitar-tuner/"); 
} 
} 

Если требуется больше информации от меня, пожалуйста, дай мне знать.

Спасибо всем!
