We have exactly the same issue. Can someone help ?

[RobertFlatt]

I didn't try to figure this one (I was only doing regression testing) but each of the two described here would be worth trying https://github.com/Android-for-Python/Android-for-Python-Users#error-expression-is-not-assignable

[pedrognsmartins]

Thanks for your feedback.
I was able to solve the issue based on your input (update cython) plus declaring on requirements specifically version 2.0.2 for greenlet.
