Does anybody know what investment I need to Adobe AIR development?
I need to buy adobe flash?
Do I need anything else that is paid?

Hello,

I have intermediate knowledge about PHP/MySQL and I have some ideas about Apps that I would like to develop (from simple business apps, to different type of dating apps).

Now I can't decide should I start learning Android SDK/Java or Adobe AIR.
Native Android can provide faster apps and higher functionality
and on other side having Adobe AIR knowledge can be used to make cross platform apps or destop...
