I got similar stacktrace. I am trying to solve it in my machine. It looks like an ndk problem...

I have the same problem. Did you find a solution?

How to downgrade your NDK to v16.

Download Android NDK, Revision 16b base on your platform here:
https://developer.android.com/ndk/downloads/older_releases

Windows:

Go to the root directory of your ndk-bundle. By default -> see the first step

1. cd ~\AppData\Local\Android
2. unzip ~\Downloads\android-ndk-r16b-windows-x86_64.zip
3. mv ndk-bundle ndk-bundle-v17
4. mv android-ndk-r16b ndk-bundle

Mac OS X:

Go to the root directory of your ndk-bundle. By default -> see the first step

1. cd ~/Library/Android
2. unzip ~/Downloads/android-ndk-r16b-darwin-x86_64.zip
3. mv ndk-bundle ndk-bundle-v17
4. mv android-ndk-r16b ndk-bundle

Happy coding!

I also have the same problem..

@Krishna-Vyas please verify your NDK version in android studio.
You can do it this way:

If your ndk version is later then v16 then check out my comment about downgrading your ndk to v 16.
If you use the proper version of NDK then you might have a problem with another dependency. Check your error log.

Thank you very much. Your solution helped me fix my app not compiling native library. Thank you.
