This is the last portion of the buildozer log.Here I am trying to build a hello world app for the android.I have kivy 1.11 installed on my system.I have also installed latest version of cython but still it fails.I have tried building with both cython 0.28 and 0.29 but still the building fails while installing Cython. I am new to Buildozer and kivy.PLease help.
