Answer 1

I solved this problem but my platform is on Mac. This may be helpful for you.

I downloaded NDK r16b from Google but found it was very different from Unity Hub. Because many files and folders were missing. Also, the detail settings of Unity won't point NDK to the right place. So I used Unity Hub to download r16b and manually set it up.

Then it worked with Unity 2019 1.14f and 2019 2.14f.

Suggestion:

• Download NDK by Unity Hub
• Manually set NDK's path in Unity

Answer 2

Use Android NDK r16b and set its path in Unity Editor.

• Download Android NDK r16b directly from https://dl.google.com/android/repository/android-ndk-r16b-windows-x86_64.zip,
  OR Find android-ndk-r16b-windows-x86_64.zip on this page: https://developer.android.com/ndk/downloads/older_releases#ndk-16b-downloads.
  OR Search Google android ndk r16b and download android-ndk-r16b-windows-x86_64.zip.

• Save it either beside Android SDK or your preferred location (Default location is "C:\Users\UserName\AppData\Local\Android")

• In Unity Editor go to Edit > Preferences > External Tools > Uncheck Android NDK Installed with Unity > Enter Path of downloaded Android NDK r16b.
