Android native function cannot be called when Build System is Gradle

Hi,
Before this problem occurred, I always packaged in internal mode, but because of project requirements, I need to introduce ARFoudation to realize plane recognition, so Gradle packaging must be used.
I use Android studio to package the native module into an AAR package, which contains a MainActivity inheriting Unity Player Activity. The package names set on both sides of Android and Unity are exactly the same. The calling method code is as follows:

jc = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");
jo = jc.GetStatic<AndroidJavaObject> ("currentActivity");
jo.Call ("PLUMEInit");

Now packaged run error reporting:
AndroidJavaException: java.lang.NoSuchMethodError: no non-static method with name='JudgeSysBlueState' signature='()V' in class Ljava.lang.Object;
java.lang.NoSuchMethodError: no non-static method with name='JudgeSysBlueState' signature='()V' in class Ljava.lang.Object;

I thought about using MainActivity without inheriting Unity Player Activity, but I don't know how to implement those inherited OnDestroy functions. Please help me, I really don't know how to solve this problem.
