Kivy Buildozer AttributeError: 'Context' object has no attribute 'hostpython'

I'm trying to build an apk for a simple python3/kivy app using buildozer in the virtual machine I got straight from kivy.org, this is day2 and still no luck. I had many errors, instaled pip, updated buildozer, pip installed morse, pnglab, sh, appdirs, setuptools for py3, but now I got this error and I must admit it really got me, anyone know what is this about? I would very much apreciate an answer as I am planning to make droid development my job some day, thank you. This is the error:

AttributeError: 'Context' object has no attribute 'hostpython'

And the traceback:

Answer Source

This arises from a bug in the new python-for-android toolchain (which the android_new buildozer target uses). You can work around it by adding your python version target to the requirements, e.g. requirements = kivy,python2.
