How can I pass arguments to Java with AndroidJavaObject.Call?

Question

Hey guys,

So i've integrated my project with eclipse and make calls to my Java classes through C# calls:

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

Now providing I dont try to pass any arguments along with the Trigger method call, it calls the method perfectly. However, if i try to pass the variable through as follows:

 jo.Call("Trigger", "my string");

The unity engine thinks the mystring arg is referring to the signature type of the method being called. How can i pass variables through along to my Java method?

On top of this, how do i return variables from java to C#? Would it be as simple as

 String myString = jo.Call("Trigger");

Thanks for the help in advance!

Did you have any luck with this? I think I'm seeing a similar issue so I wouldn't be able to help with the first part of your question. However as to returning variables it's almost as simple as you say. You would just need to add something link this;

 String myString = jo.Call<String>("Trigger");
