I want to make a social application for our school. It will include a forum, radio, announcements section etc. but I need some more knowledge first.
I have never coded for mobile systems before, how can I code for Android and iOS?
How can I reach same data from different applications(networking etc.)?
How can I create a database?
I think it would be easy if I can display a webpage in an application, how can I do it?
Well, there surely are ways, but interaction with device from C++ code would be much more difficult. There are readily available libraries in Java that support interaction with various device's features, like networking, display, touch screen, battery etc. They are well supported by Google and easy to use. Porting to C++ means a lot of hassle on your end, shortage of available resources, reinventing the wheel and so on.
