MediaPlugin: Plugin.Media.Abstractions.MediaPermissionException

When I debug my app in Android API 19 it works but when I debug in Android API 24 the exception “Plugin.Media.Abstractions.MediaPermissionException: Camera permission (s) is required” is displayed when I want to access the camera and this exception comes out when I want to select a photo from the gallery “Plugin.Media.Abstractions.MediaPermissionException: Storage permission (s) are required”.

                });
            }

            if (file != null)
            {
                imageSource = ImageSource.FromStream(() =>
                {
                    var stream = file.GetStream();
                    file.Dispose();
