Can not Binding a .JAR

I got a .jar named "dji-sdk-provided-4.4.1.jar" from this site:https:$$github.com$dji-sdk$Mobile-SDK-Android.
When I try to bind this jar to dll follow the walkthrough of "Binding a .JAR" I got 7012 warnings.
And I can not find some namespaces("Dji.Sdk.Base","Dji.Sdk.Sdkmanager"...) in the dll.
The attachment is the file to be binding. I just rename it to "dji-sdk-provided-4.4.1.zip"
Any comments and suggestions will be appreciated.
