[Unity] Resolving the "ANDROID_NDK_ROOT is undefined or empty" error

Conclusion

• Select an appropriate folder in File → Build Settings → Export and try building once.
  • This will enable you to build.
• Or refer to the following article:
  • Open Preferences and in "External Tools,"
    uncheck "Android NDK Installed with Unity (recommended)" and then
    check it again before running the Android build. This successfully completed the build.

The environment variable ANDROID_NDK_ROOT is undefined or empty, is the Android NDK correctly installed?

Attempting to run the Unity build from the editor (script)

• Instead of the standard File → Build Settings → Export, I was trying to build using BuildPipeline via a script.
