[PyQt] PyQt and JNI

[Kálmán Viktor]

As I see the QAndroidJniObject handles almost everything so that would be
the most useful, however I don't know what would be the minimal subset of
those functions/static members that would be enough. There is a small
example on the Qt blog using the class, maybe those that are used there:
