find method failed

[Lv9S]

smali代码： .method public static varargs native cL([Ljava/lang/Object;)Ljava/lang/Object; .end method

调用代码： Number ret = clazz.callStaticJniMethod(emulator, "cL([Ljava/lang/Object;)Ljava/lang/Object;", vm.addLocalObject(new ObjectArray(objArr)));

报错： Exception in thread "main" java.lang.IllegalArgumentException: find method failed: cL([Ljava/lang/Object;)Ljava/lang/Object;

要测试代码才能检查
