Using AndroidJavaObject.CallStatic to retrieve a return value

Hi all,

I'm having some issues getting AndroidJavaObject's CallStatic to work for any primitive type, when a return value is expected. I am able to call void methods without issue.

In C#, I'm declaring the object as such:

 public AndroidJavaClass myJavaClass = new AndroidJavaClass("com.myapp.....");

Here's where it gets weird. Given two Java methods in that class:

 public static void methodA(final String parameter)
 {
 ...
 }
 
 public static boolean methodB(final String parameter)
 {
 ....
 return true;
 }

The latter is not working when called from C#.

There is no problem with the void method, which executes its Android native code as intended, when called as such:

 myJavaClass.CallStatic("methodA", "hello world");

However, I am getting JNI exceptions when I call:

 bool myBool = myJavaClass.CallStatic<bool>("methodB", "some paramter");

I am not sure what is wrong with #2 here, but Unity definitely doesn't like it:
