Hi, From my own experimentation it seems that the handles just don't work for me. They make the calls to java and return a handle, but after this, the amazon C++ code try to do something (what I don't know) that creates a classdefnotfound exception which crashes the application. I switched to using the callbacks.
Hello xfhe, We cannot actually reproduce the crash that you are experiencing using the current HandleWrapper methods that are exposed. However, please open a new thread with the exact methods that you are attempting to use at the time of the crash since to this post's thread since it was opened in 2012, the interface that the original post doesn't exist as of the latest version of the GameCircle SDK.
