接受权限后重新加载 webview 的问题，经过太多的研究，找到了这段代码并复制了下面的代码，100% 工作，我希望你的问题得到解决：-

mwebView.setWebChromeClient(new WebChromeClient() {
        @Override
        public void onPermissionRequest(final PermissionRequest request) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                myRequest = request;
                for (String permission : request.getResources()) {
                    if (permission.equals("android.webkit.resource.AUDIO_CAPTURE")) {
                        demandForPermission(request.getOrigin().toString(), Manifest.permission.RECORD_AUDIO, MY_PERMISSIONS_REQUEST_RECORD_AUDIO);
                    } else {
                        myRequest.grant(request.getResources());
                    }
                }
            }
        }

        @Override
        public void onPermissionRequestCanceled(PermissionRequest request) {
            super.onPermissionRequestCanceled(request);
        }
