Question

我已经实现了WebChromeClient，并且从onPermissionRequest开始，我无法访问应用程序内部的“相机和音频”。

我的代码是

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

        final String[] requestedResources = request.getResources();
        for (String r : requestedResources) {
            if ((r.equals(PermissionRequest.RESOURCE_VIDEO_CAPTURE)) || r.equals(PermissionRequest.RESOURCE_AUDIO_CAPTURE)) {
                request.grant(new String[]{PermissionRequest.RESOURCE_VIDEO_CAPTURE,PermissionRequest.RESOURCE_AUDIO_CAPTURE});
                break;
            }

        }
    }

但是我不断收到如下异常和错误

Answer 1

如果您在第一行中有super通话

super.onPermissionRequest(request)

然后，您可能无法像尝试下一个循环那样再次“手动”调用grant或deny。将您的代码移至super调用上方，并确保不会为您自己处理的权限调用super-使准备的PermissionRequest没有这些，如果不为空（要求其他权限），则将此修改后的请求致电super

还请确保整个应用程序已获取适当的权限

将摄像机和音频的权限授予WebView？
