step1) use Android studio and make a AAR Plugin

step2) setting the Unity Directory( Asset - Plugin - Android) by locating Dji SDK(JAR File) And Android Plugin(AAR File)

step3) edit C# script in Unity and build it

step4) ten Unity gave me the error message like this

=======================ERROR=============================================== Ignoring InnerClasses attribute for an anonymous inner class (org.bouncycastle.asn1.ASN1InputStream$1) that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a compiler that did not target the modern .class file format. The recommended solution is to recompile the class from source, using an up-to-date compiler and without specifying any "-target" type options. The consequence of ignoring this warning is that reflective operations on this class will incorrectly indicate that it is not an inner class.

================================================================== here is my quistion
