Ooooops! A further update. I tried building an a newer Daily Build (#2972) for Amazon and the build error returned:
Nov 01 09:26:29.799 ERROR: An error occurred during build (corona.build.7). The server returned the following message: --- A device build error occurred on the server. Error: Error packaging APK. Potential conflict between resources or plugins. BuildID: 581897fb4b22d --- Nov 01 09:26:29.799 Nov 01 09:26:29.810 Android build failed (5) after 12 seconds Nov 01 09:26:30.077 ERROR: Build Failed: A device build error occurred on the server. Error: Error packaging APK. Potential conflict between resources or plugins. BuildID: 581897fb4b22d Error code: 5
Then I changed to Corona #2943 and the app again built just fine.
Then I changed to Corona #2972 and it errored again.
Then I changed to Corona #2943 and it built just fine.
So it seems reproducible.
