无法从相机SD卡中下载原图
Completed
MSDK版本：V5.2.0
目标：从摄像头的SD卡中下载原图至遥控器（摄像头为P1摄像头，无人机为M300 RTK）
问题：
1、请反馈我的图片下载API调用步骤是否有问题，若无问题是否API问题？
2、以及，我是用JAVA进行API调用的，V5 SDK中是否存在只能使用kotlin语法特性的API。
做法：
1、新建空白项目，导入MSDK，进行APP注册。
注册调用API：
SDKManager.getInstance().init(this, new SDKManagerCallback(){});
2、利用MediaManager进行原图下载
下载依次调用API：
IMediaManager mediaManager = MediaDataCenter.getInstance().getMediaManager();
mediaManager.addMediaFileListStateListener(mediaFileListState -> {
});
mediaManager.enable(new CommonCallbacks.CompletionCallback() {});
MediaFileFilter mediaFileFilter = MediaFileFilter.PHOTO;
mediaManager.pullMediaFileListFromCamera(new PullMediaFileListParam.Builder().filter(mediaFileFilter).build(), new CommonCallbacks.CompletionCallback() {});
MediaFileListData mediaFileListData = mediaManager.getMediaFileListData();
List<MediaFile> mediaFiles = mediaFileListData.getData();
MediaFile mediaFile = mediaFiles.get(0);
结果：返回mediaFileListData为空，无法获取原图。

测试过Sample。我按照您说的做了，可以拉取到MediaFileListData了，但是仍然无法获取到原图，您可以帮我看看我接下来的API调用是否有问题吗？

如果你M300RTK用得是H20系列镜头，则可以边拍照边下载。闪退你总有闪退日志吧。pullOriginalMediaFileFromCamera第二个参数也有callback可以看到是什么情况呀。如何下载照片看这篇文章，https://sdk-forum.dji.net/hc/zh-cn/articles/11810412570393
