Android: WebView - not getting Camera and Mic enabled for conference

Question

We connect to https://meet.jit.si for video conference. If we use a chrome browser on Android device (tested on both Android 7 and 10), we are able to join with both Camera and Mic enabled. Able to turn them on and off as well. But if we try the same using a webview, we are not even getting a prompt from the website to allow access and get a "Failed to access camera/mic" error when trying to turn them on.

This is our code.

Manifest

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

Getting runtime permission on load

    String[] permissions =
            {Manifest.permission.READ_EXTERNAL_STORAGE,
             Manifest.permission.WRITE_EXTERNAL_STORAGE,
             Manifest.permission.INTERNET,
             Manifest.permission.RECORD_AUDIO,
             Manifest.permission.CAMERA};

    ActivityCompat.requestPermissions(
            this,
            permissions,
            1010);

Loading the webpage into WebView

String url = "https://meet.jit.si/testingconf49854";
WebView webView = findViewById(R.id.webView);
WebSettings mWebSettings = webView.getSettings();
mWebSettings.setLoadsImagesAutomatically(true);
mWebSettings.setBlockNetworkLoads(false);
mWebSettings.setJavaScriptEnabled(true);
mWebSettings.setLoadWithOverviewMode(true);
mWebSettings.setUseWideViewPort(false);
mWebSettings.setTextZoom(70);
mWebSettings.setCacheMode( WebSettings.LOAD_NO_CACHE );
mWebSettings.setUserAgentString("Mozilla/5.0 (Linux; Android 5.1.1; Nexus 5 Build/LMY48B; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/43.0.2357.65 Mobile Safari/537.36");
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(true);

Map<String, String> noCacheHeaders = new HashMap<String, String>(2);
noCacheHeaders.put("Pragma", "no-cache");
noCacheHeaders.put("Cache-Control", "no-cache");
webView.loadUrl(url, noCacheHeaders);

Please let us know what we are missing here. Appreciate your help.

After getting those permissions, you need to override onPermissionRequest in WebChromeClient like this:

webView.setWebChromeClient(new WebChromeClient() {
  @Override
   public void onPermissionRequest(final PermissionRequest request) {
       request.grant(request.getResources());
}
});
