APK grows in 4.9 and hwo to get rid of VR plugins?

My projects has grown about 3MB from 4.8.3 to 4.9.0 and after disabling all unnecessary plugins the size keeps the same.

Noticed a libvrapi.so inside the APK file in LIB folder that I believe my project doesn’t need it. How I can get rid of it? Disabling the VR pugings don’t do nothing, the file with about 1MB are still there.

My cotent assets file also grow, while I haven’t made any change to my game content after migrating. There is any possibility that some engine content has jumped in my project after the upgrade?

Kind regards,
piX

I have found this:

The plugs dialog is accessed from the Edit menu. You will need to have a code project for changes to take effect since this will need to compile a new library without the code; enabled plugins are compiled into the same .so on Android and iOS. If you only have a content-only project (Blueprints and no C++), you can just add an empty class to make it a code project. Staying under the 50 MB limit - Mobile Development - Unreal Engine Forums

Trying it, installed VS 2013 community, added a new C++ class to my project, without adding any code. Package it again and now the Build fails.

Also when I add a new C++ class to my project it don’t show in my content browser.

Update, new test:
Created a new C++ clean project from 2D SideScroller… Disabled all VR plugins… compile and package to android…
Anyway the libvrapi.so is still there…
