hi there, what _exactly_ do you want ?
ie, there is no core.so for android, rather an opencv\_java.so
(which is statically linked against the opencv modules)

I was trying to create an app and also implement opencv in it
But the source I was using said there has to be a libcore.so file in the android sdk version
I’m using aide app though
I have looked for the sdk version but don’t know which one exactly
I even downloaded 4.10.0 and 4.9.0 versions but it’s just the java.so file that is there
The purpose was that I wanted to use the opencv native capabilities to create the app
If there is any way you can assist me to get more details
I would be grateful

doing what, exactly ? a c++ app ?
(the sdk is more focussed on java/kotlin based apps)
and again, there is no `libcore.so` at all
(probably meant: `libopencv_core.so` ?)
, but again, it won’t build that on android unless you specify `BUILD_SHARED_LIBS=OFF` in cmake

The source was Google Gemini
It was so frustrating
I was trying to build an app using aide and also implement opencv
I was using my mobile phone though coz I don’t have a PC and I was told that I can use aide to build and run a app
The purpose of the app is to detect hidden fruits in a game…
But Gemini is saying I can’t implement my code without the core.so files
I wanted to use opencv native libraries to implement which it said would be the best but it was so frustrating as I began to download all recent versions and looking for the core.so file in almost all the versions
Pls what’s your advice on this
Should I go without the core.so file

that’s not a source, but a hallucination

you won’t be able to build anything opencv related without.
please, do better research, before asking, thank you
