[Android] OpenCV stitching fails due to missing directory

[wojciechzahradnikdeviniti]

Hello,

During the execution of panorama stitching, the operation fails with an OpenCV error indicating that a required directory cannot be found. As a result, the app restarts due to failed stitching.

I'm using this branch: https://github.com/maxal-studio/flutter-plugin-camera360/tree/added-stitcher-settings

Logs:

OpenCV(4.8.0) Error: Requested object was not found (could not open directory: /data/app/.../base.apk!/lib/arm64-v8a) in glob_rec, file .../opencv-4.8.0/modules/core/src/glob.cpp, line 279
