      class ILDMManager

      interface ILDMManager
      Package:dji.v5.manager.interfaces
      Description:

      LDM(Local Data Mode) manager is used to enable or disable the LDM mode. After enabling LDM, the MSDK's internet access will be restricted. You can callenableLDMto enable LDM mode. Also, you can configure the exempt modules when enabling the LDM in order to allow those modules to access internet. For example, allowing RTK module as an exempt module in LDM will allow the RTK module to connect with RTK server to ensure the accuracy of navigation. Also, allowing a flysafe module as an exempt module in LDM can still access the flysafe ever to ensure the safety of flight. You have to apply successfully from our developer website(https://developer.dji.com/user/ldm/) and receive a LDM licence in order to use this feature.

      Supported since MSDK 5.0.0

      method isLDMLicenseLoaded
      boolean isLDMLicenseLoaded()
      Package:dji.v5.manager.interfaces
      Description:

      After callingenableLDM, MSDK will check if there is a local LDM license. Otherwise, it will ask the server to transmit a LDM license. If the LDM license has been loaded and activated, then returntrue.

      Supported since MSDK 5.0.0

      Return:
      booleantruemeans the LDM certificate has been loaded and activated.
      method isLDMEnabled
      boolean isLDMEnabled()
      Package:dji.v5.manager.interfaces
      Description:

      Return whether the LDM is enabled.

      Supported since MSDK 5.0.0

      Return:
      booleantruemeans LDM is enabled.
      method isNetworkServiceEnabledForModule
      boolean isNetworkServiceEnabledForModule(LDMExemptModule module)
      Package:dji.v5.manager.interfaces
      Description:

      Check the internet access of input LDMExemptModule.

      Input Parameters:
      LDMExemptModule moduleLDM exempt module.
      Return:
      booleantruemeans LDM is not enabled or the input LDMExemptModule still has internet access when LDM is enabled.false means LDM is enabled and the input LDMExemptModule has no internet access.
      method loadLocalLDMLicenseContent
      IDJIError loadLocalLDMLicenseContent(String content)
      Package:dji.v5.manager.interfaces
      Description:

      Load the content of LDM license, the content is the license_appname.txt given by developer website after successfully applying the LDM license.

      Supported since MSDK 5.0.0

      Input Parameters:
      String contentThe content of LDM License, the content is the license_appname.txt given by developer website after successfully applying for the LDM license.
      Return:
      IDJIErrorReturn the loading execution result of LDM License. The result is successful if returning null.
      method getLocalLDMLicensePath
      String getLocalLDMLicensePath(Context ctx)
      Package:dji.v5.manager.interfaces
      Description:

      Get the saved path of the offline LDM license. Please put the offline LDM license under this directory.

      MSDK 5.0.0 start support

      Input Parameters:
      Context ctxCurrent application's context
      Return:
      StringReturn the saved path of the offline LDM license.
      method
      enableLDM
      method enableLDM
      void enableLDM(Context context, CommonCallbacks.CompletionCallback callback, LDMExemptModule... modules)
      Package:dji.v5.manager.interfaces
      Description:

      A method of enabling LDM mode. When calling this method, you can pass multiple LDMExemptModule parameters in. It means the exempt modules when LDM is enabled. E.g. When you pass RTK and FLY_SAFE in, those modules can still access internet after enabling LDM.
      Note:
      1. You have to call this method after calling SDKManager.init() method in order to enable LDM. If you don't have an offline license, then you need to pass this parameter in, MSDK_INIT_AND_REGISTRATION. This will allow MSDK registration module to complete the registration.
      2. Make sure your offline LDM license（license_appname.txt）is saved in the correct directory when you use an offline LDM license to enable LDM. You can use getLocalLDMLicensePath to get the offline LDM License path.
      3. Except save the offline LDM license to the specified path, you can also call loadLocalLDMLicenseContent to load the content of LDM license to the LDM module.
      4. If you don't have an offline LDM license, the first time you call this method will access DJI LDM server to download the LDM license. Later on, calling this method will read the local cache.
      5. If you want to use the offline LDM license, you need to apply fromhttps://developer.dji.comloin your user account and apply.
