invoke function throws IllegalArgumentException expected 0, got 1 when passing null args

I try to use reflect to call the android.app.ActivityThread.currentActivityThread() function

val currentActivityThread = invoke_static_method("android.app.ActivityThread",
                "currentActivityThread",
                arrayOf<Class<*>>(),
                arrayOf<Any>())

fun invoke_static_method(className: String,
                         methodName: String,
                         pareTypes: Array<Class<*>>,
                         pareValues: Array<Any>): Any?{
    try {
        val objClass: Class<*> = Class.forName(className)
        val method = objClass.getMethod(methodName,*pareTypes)
        Log.d("dump",method.toString()+pareValues.size)
        return method.invoke(null,pareValues)
    }catch (e: Exception){
        Log.d("dump",e.toString())
        e.printStackTrace()
    }
    return null
}

From the log,I've alrady got this method

D/dump: public static android.app.ActivityThread android.app.ActivityThread.currentActivityThread()0

D/dump: java.lang.IllegalArgumentException: Wrong number of arguments; expected 0, got 1

I don't know why invoke throws out IllegalArgumentException since pareValues has been correctly initialized

Thx for any help
