在Windows 9上使用相机“1”的Sinch VideoCaptureThread问题

Question

我正在制作一个小应用程序，我使用sinch进行视频通话，它在Android 8.1及更低版本上运行良好。但是在android 9上，当我进行视频通话时，我的应用程序崩溃了。这是错误：

尝试这种方法用相机拍摄视频可能会对你有所帮助： -

public void dispatchTakeVideoIntent() {
        PermissionUtil.with(this).setCallback(new PermissionUtil.PermissionGrantedListener() {
            @Override
            public void onPermissionResult(boolean isGranted, int requestCode) {
                if (isGranted) {
                    Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
                    if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
                        startActivityForResult(takeVideoIntent, AppConstants.REQUEST_CODE.REQUEST_VIDEO_CAPTURE);
                    }
                }
            }
        }).validate(Manifest.permission.CAMERA);
    }
