How to call Java method from C++

Question

I am using JNI to call my C++ function from Java. One of the C++ function's arguments is jobject thiz (as far as I know, all JNI native functions have this argument). The function takes quite long to complete and I want to report progress back to the jobject thiz Java object, so that I can show the progress to the user. How can I call jobject's methods from C++?

You need to look at the JNI functions GetMethodID and Call<type>Method*.

The details of the various variants and how to call them are documented the JNI specification.
