Camera access in web view in android

Question

I have below code added using other stacker over follow solution sites:

  mBinding.webView.setWebChromeClient(new WebChromeClient() {
            @Override
            public void onPermissionRequest(final PermissionRequest request) {
                Log.d(TAG,"onPermissionRequest");
                
                mPermissionRequest = request;
                final String[] requestedResources = request.getResources();
                for (String r : requestedResources) {
                    if (r.equals(PermissionRequest.RESOURCE_VIDEO_CAPTURE)) {
                       requireActivity().runOnUiThread(() -> {

                           CustomDialogNew customDialog1 = CustomDialogNew.getInstance();

                           Runnable runnable = () -> {
                               customDialog1.dismiss();
                               mPermissionRequest.grant(new String[]{PermissionRequest.RESOURCE_VIDEO_CAPTURE});
                               Log.d(TAG, "Granted");
                               loadUrl(lastUrlLoaded);
                           };

                           customDialog1.init(0, getString(R.string.message),
                                   false, getString(R.string.ok), "", runnable,
                                   null);
                           customDialog1.show(getParentFragmentManager(), TAG);
                       });
                    }
                }
            }

            @Override
            public void onPermissionRequestCanceled(PermissionRequest request) {
                Log.d(TAG,"onPermissionRequestCanceled");
                //super.onPermissionRequestCanceled(request);
            }
        });

Above logic not working when I grant permission after that when I reload the url that time I see black screen for camera, camera not open as expected.

Any help is apperciated!

In Webview you need to have a method which triggers Android method and by which you can achieve you functionality. Search about JavascriptInterface Also make sure before using camera ask the relevant permissions.
