I followed some of the points listed in the docs about making apk smaller. In particular I tried blacklisting engine’s stuff and some of the content I have in my project.
It didn’t seem to work at all. Since engine content is outside of the project’s folder, I had to use absolute path in PakBlacklist-Development.txt - that didn’t work (and yes, I was deploying Development build). Then I added relative path to my content folder - that didn’t work either.
The only way I was able to “blacklist” content of the project was through Project settings. I could not do that for engine’s content.
The blacklist does work on engine content, but you must follow the exact relative path in the doc: “…/…/…/Engine/Content”. Be very careful with the blacklist; it will allow you to remove stuff that may be necessary for the engine to work.
