Buildozer failed to execute the last command

Probably you are running an updated version of cython, all major release start form 0.21 and up, you have to downgrade cython to 0.20 ( sudo pip install cython==0.20 ) then removing .buildozer folder ( rm -Rf .buildozer ) and then rebuilding with 'buildozer android debug'

First raise the log level = 2 in buildozer.spec,then it will show all logs and error clearly. Here in .buildozer/android/platform/python-for-android/dist/myapp/python 2.7 build.py was missing. To fix this issue run this command buildozer android clean and then rebuild it using buildozer android debug or automatically run using buildozer android debug deploy run.
