Question about extending QtAndroidExtras

[Kálmán Viktor]

My idea was that with a single string argument and string return value
users can simply pass in/return JSON and that would cover multiple
arguments and string/int/bool/float/list/dict types.

It's a little hacky but probably still nicer than hacking Qt and pyjnius
together.
