Error compiling Cython file in buildozer

I have built an android app using kivy and while I was compiling it to build an apk using buildozer, the following error popped up;

# In case of a bug report, please add a full log with log_level = 2

I know that there is some issue with latest version of cython and so I downgraded to cython==0.20 but no luck, still the same error. I have already compiled two more programs using buildozer by downgrading cython but now, in this case, I don't know whats happening. Some other answers here say that raising log level 2 in buildozer.spec file will clarify the details of the error but I am new to buildozer. I don't know how to do that.

Also, this process takes too long while it downloads SDK tools and so I am limited with resources. I request humbly to please help me getting rid of this error.

Thanks in advance!

I had something very similar in regards to cython versions. I only ever managed to get my buildozer to work with cython 0.23. It took many hours and many reinstalls to figure that out...

Perhaps give cython 0.23 a try. I can personally confirm that it works with buildozer 0.34.dev0.
