XML page

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission-group.MICROPHONE" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-feature android:name="android.hardware.camera2" android:required="true" />





    <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=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

Java page

public WebView webView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_main);

    webView = (WebView)findViewById(R.id.webView);
    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    webView.loadUrl("https://.online"); //web url

    webView.setWebViewClient(new WebViewClient()); //to prevent openning new window
    webView.setWebChromeClient(new WebChromeClient(){
        @TargetApi(Build.VERSION_CODES.LOLLIPOP)
        @Override
        public void onPermissionRequest(final PermissionRequest request) {
            request.grant(request.getResources());
        }
    });


}

I tried searching but the only thing I found is for marshmallow and up version
