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
