Issue in Cython file compilation and building kivy.graphics.vertex_instruction extentions

[jayece09]

Hi!
I am trying to build .apk file using python for android and Kivy. The error returned on multiple occasions even after changing versions of Cython:-
building 'kivy.graphics.vertex_instructions' extension

Closing since the issue is old and both kivy and p4a have changed a lot since then. If you experience this problem, please report it on the kivy-users or python-for-android mailing lists.
