Invoke method with parameters

Question

I have a problem with reflection.

The very essence: there is a bunch of methods in the class. I find it necessary this way (it's all good here):

invokingMethod = InstanceClass.getMethod(AMethodName, AArgumentTypes);

Then I want to call him:

result = invokingMethod.invoke(AInstance, AArgumentObjects);

The number of parameters can be different. Here, simply calling the authorization method and therefore only two parameters

Signature of the method:

public abstract long userLogin(java.lang.String,java.lang.String) 

Content AArgumentsTypes:

Content AArgumentObjects:

And as a result I have an error about the wrong type of parameters passed.

Works only if you explicitly pass all parameters to a function. Or I use AArgumentObjects[1] in the debug menu variable (if I change it in the code, the errors remain):

After calling from the code with AArgumentObjects[1]:

Answer 1

我以这种方式解决了问题，谢谢大家：

 result = invokingMethod.invoke(AInstance, ((Object[])AArgumentObjects[1]));
