Is there any way to extend the default GameActivity.java or provide a custom one, and add more java files to my game project without directly changing or adding files at the engine folders? How can I include these new files in the build process?
Thank you for your help, I was able to do it using the references you provided. However, I still find the documentation lacking, in such things as the description of the Build.cs classes interfaces and of the UPL system itself. As soon as I finish my project and have some time I’ll try to prepare something.
