File not found (what is going on?)

whenever I try to build for android UE4 tells me that it can’t find a file and that I should include it, even though it already is included. What does unreal want from me?

When I remove that and AIBlueprinthelperLibrary.h it doesn’t complain anymore.

Hi,PasteteDoeniel! Well to use this header file you should include the “HeadMountedDisplay” module to your build.cs file and regenerate the project!Cause this header file is in this module and by default its not included in project!
