Python 3 fix for android package

[wolfgangp]

This should work with Python 2 and 3. It's tested on Python 3.5 only. I did test .decode on unicode and regular str in Python 2.7 and it's fine.
Without this change, a buildozer requirements line like this
requirements = python3crystax,kivy==master,pyjnius,android
will result in a python error stating that a string cannot be concatenated to a bytes object, i.e. JAVA_NAMESPACE is a bytes object.

Thanks, looks good but I'll test under python2 before merging.

(JAVA_NAMESPACE.decode() if type(JAVA_NAMESPACE) is bytes and type('') is not bytes else JAVA_NAMESPACE) is a ternary that would return the base string type regardless of interpreter, but im sure his patch is fine.

I was able to test python3 successfully with buildozer.spec
requirements = python3crystax,kivy,git+git://github.com/wolfgangp/python-for-android
After I did buildozer android clean

Just to make sure I understand before testing/merging, this was a problem when running on host Python3 only right?
So if I run buildozer/p4a with these requirements from host python3 I should see the issue, correct?

[wolfgangp]

Yes, only running Python 3 will elicit the problem p4a had. I think tests confirming this works in Python 2 are not in.

@AndreMiras @wolfgangp It doesn't make sense to decode it at that place because if something calls it (or the jni part), it'll fail. Ref: #1475

[wolfgangp]

I'm fine with closing this, as KeyWeeUsr's fix is more to the point.
