Unable to create Minicap object using minicap_create #219

I have followed the below steps

1. Taken the header Minicap.hpp from /jni/minicap-shared/aosp/include/Minicap.hpp
2. Taken the minicap.so from /jni/minicap-shared/aosp/libs/android-29/arm64-v8a (running the app in android 10)
3. On launching the app, I tried to create minicap object using minicap_create(0) which returns null

I am stuck here. Please let me know how to create the Minicap object. Is my approach incorrect?

Is it required to copy any files to the android system?
