Description
I have compiled a very basic helloWorld app as below. The app works fine on Ubuntu and also compiles fine into apk using buildozer.
__version__ = '1.0'
from kivy.app import App
from kivy.uix.button import Button
class Hello(App):
def build(self):
btn = Button(text='Hello World')
return btn
Hello().run()
When I run on Android the app immediately closes before displaying the hello world screen. After working through logs produced with adb logcat I see the following...

This appears to be the same issue raised as 1691 under the title "unicode error during startup (python3, numpy, opencv) - patch included #1691". If I am reading this patch correctly the current file _android.pyx should have the following changes
removed this line
python_act = autoclass(JAVA_NAMESPACE + u'.PythonActivity')
added these lines
java_namespace = JAVA_NAMESPACE.decode() if isinstance(JAVA_NAMESPACE, bytes) else JAVA_NAMESPACE
python_act = autoclass(java_namespace + u'.PythonActivity')
Yet when I look at the current code on Github for _android.pyx I do not see these changes applied. Has this fix somehow been removed from the current version? How can i apply this fix to my system?
