WebContentsDelegate::CheckMediaAccessPermission: Not supported. 貌似是app有权限，但是xwalk没权限 xwalk没有webView.setWebChromeClient(new WebChromeClient(){ @TargetApi(Build.VERSION_CODES.LOLLIPOP) @OverRide public void onPermissionRequest(final PermissionRequest request) { request.grant(request.getResources()); } });

从log看，有两个问题：
1.摄像头及声音权限问题
2.SSL握手没有成功
