android - 06-16 12 :05:46. 802 : E/chromium(15693): [ERROR:audio_manager_android. cc(239)] 无法选择音频设备

Question

我正在使用 xwalkview 在 android 中构建视频/音频通话应用程序。在进行音频/视频通话时，我不是每次都收到此错误 90% 次，因此我没有收到任何一方的视频。我添加了 Record_Audio,camera,Modify_audio_settings 的权限。

接受许可后重新加载 webview 的问题，经过大量研究，发现此代码并复制以下代码并 100% 正常工作，我希望您的问题能够解决:-

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);
        }
