I'm trying to generate an APK via buildozer, but this error ocurred:

My requirements are kivy, psycopg2, python3, sqlite3 and datetime. I'm trying to compile to Android API 27 and NDK 17c. How can I fix it?

Can't say much without the config.log or buildozer.spec file.
Keep in mind this is a bug tracker, if what you're looking for is actually support give this a try instead https://github.com/kivy/python-for-android#support
