Packaging project on Android using OpenCV plugin on Unreal 5.3.2

Hello,

I am doing a project using the OpenCV plugin, It works well on windows but when I try to package it for Android or run it on my Android phone I get this error:

Missing precompiled manifest for 'OpenCVHelper' , 'D:\UE_5.3\Engine\Plugins\Runtime\OpenCV\Intermediate\Build\Android\UnrealGame\Development\OpenCVHelper\OpenCVHelper.precompiled'. This module was most likely not flagged for being included in a precompiled build - set 'PrecompileForTargets = PrecompileTargetsType.Any;' in OpenCVHelper.build.cs to override. If part of a plugin, also check if its 'Type' is correct.

Here is my build setup :

I have tried moving the OpenCV folder from the engine plugin to my project plugin as sugested on the internet and it still doesn’t work, it says that it cannot find OpenCV source code like imgproc.hpp for example.

I have built android app before, everything Android side (sdk…) should be well setted up.

Help please :slight_smile:

Have you managed to figure this one out?
