    这个看不出什么，能否把前后文说一下呢？你是使用LDM还是LDM PLUS，调用哪个接口出问题的，你的操作步骤是什么？

    调用这个函数出错

    DJISDKManager.getInstance().registerAppForLDM(context, callback);

    额 LDM和LDM PLUS的区别是什么

    LDM模式的介绍：https://sdk-forum.dji.net/hc/zh-cn/articles/4404611910425 普通LDM，首次注册仍然需要网络，注册后打开LDM以后下次登陆就不需要网络了。 LDM PLUS，是申请到一个离线文件，放到app下第一次注册也不需要网络。 registerAppForLDM这个接口别用了，你直接按照我给你的链接里描述的方式用。

    我是LDM PLUS,registerAppForLDM不调用这个,有了离线文件可以直接调用

    registerApp

    吗

    你有LDM PLUS就不需要调用任何LDM相关的接口，直接调用registerApp就行了。LDM的类是为普通LDM服务的。

    在这反馈一个问题

    DJISDKManager.LDM_PLUS_LICENSE_ROOT_PATH

    这个地址不是特别精准

    比如Android10下的返回String为

    /storage/emulated/0/Android/data/app包名/files//DJI/

    改为/storage/emulated/0/Android/data/app包名/files/DJI 会好些

    DJISDKManager.LDM_PLUS_LICENSE_ROOT_PATH 是代码生成的，不知道为啥会有两个//，我们会检查一下。
