[Development] Android / IOS

[md at rpzdesign.com]

Hello Development:

I am newly arrived on Qt 5.2x scene and wanted to know how to contribute 
code, fixes,
and testing for Qt 5.3.x of IOS and Android.

Specifically, I want to focus on QT C++ <-> Objective C/Cocoa bridge
and QT C++ <-> Android/Java/JNI.

Is the development email list a free flowing forum or are there 
different subgroups
each with their own list or developer forum somewhere.

Where can I access threads of those focused on Android and IOS 
integration issues?

Thanks for any replies,

Marco
