I have tried through several answers like apk split , Flavors Build but it does not works for me.

I'm building an Android app with min sdk 15, which uses opencv library.The problem is when I build apk size of it is more then 60 MB which is not very great.

I checked the app file, I could see that the size is too big due to libopencv_java3.so file in all architectures like amr64, armeabi, mips, x86 etc.

I am using openCv only for image processing.This library has a lot of other features like video processing, 3d image, object detection and much more, which I don't need in my app like

If I remove all those files and build APK, then size will be reduced 50 mb , but to make this app work I need to install OpenCVManager to run my app.

Is there any way by which I can reduce my apk size?

Or is it possible just to extract only the feature from openCv which I am intersted in and create .so for those features?

i'm no more using android, but you'd have to build your own sdk with a reduced opencv_java.so, and use static initialization (init_Debug() or what it was called), and NOT using the opencv manager, right ?

meaning: you'd have to interfere with cmake and choose a limited set of modules (not all there is), when building opencv_java.so.

You should consider splitting your APK into architecture specific versions:

https://developer.android.com/google/...

That way you only need to include one version of OpenCV pr. APK, e.g. arm64-v8a.

That should give you the size reduction you're looking for.
