I follow the instructions from https://sdk-forum.dji.net/hc/en-us/articles/9168348360345-Chapter-3-Integrate-the-SDK-into-your-project. When I attempt to build I get that the class **com.secneo.sdk.Helper** is not found. The class is needed because I have my own call back registration handler and logic in my application. In other words, I use the uxsdk as a library, so the classes need to be unencrypted. This worked in prior 5.7 version. I need the newer version because of having "fd" file descriptor crashes in 5.7 video streaming. Please help!
