1. Introduce the classes.jar package of unity. I will install unity-5.6.1 in D: \ program files \ unity-561 \ unity \ editor \ data \ playbackengines \ androidplayer \ variations \ mono \ release \ classes \ classes.jar
If you directly import classes.jar into the androidstudio project and compile AAR, unity compilation will report an error:
