In our app we have SIP module (pjsua2), which has the JNI libs **libc++\_shared** , **libpjsua2**

- When we try to integrate Zoom SDK(mobilertc and commonlib) we are getting compile exception saying

_2 files found with path ‘lib/arm64-v8a/libc++\_shared.so’ from inputs:_

_- pjsua2/build/intermediates/library\_jni/debug/jni/arm64-v8a/libc++\_shared.so_

_- /mobilertc/build/.transforms/445b8adf65ed1845334c5eaf41712982/transformed/jetified-mobilertc/jni/arm64-v8a/libc++\_shared.so_

I tried to use packageOptions pickfirst like below to resolve this

```auto
android{
  packagingOptions {
      pickFirst 'lib/x86/libc++_shared.so'
      pickFirst 'lib/x86_64/libc++_shared.so'
      pickFirst 'lib/armeabi-v7a/libc++_shared.so'
      pickFirst 'lib/arm64-v8a/libc++_shared.so'
  }
}

```

With this I am able to run the project with this I tried to invoke below

- Initialise Zoom SDK - Success

- When I am trying to join the call

ZoomSDK.getInstance().getMeetingService().joinMeetingWithParams

- With this the exception throws **libc++\_shared**
