What’s AIR™?
 .air Packages

Adobe Integrated Runtime
(AIR) is a cross-platform
runtime that allows you to
leverage your existing web
applications skills to build
and deploy Rich Internet
Applications (RIAs) to the
desktop

 Deploy to desktop
with double click
install
 Distribute as
standalone or
packaged with
runtime
 Remember JWS?

Flex for developers
• Actionscript ~ Javascript + Java.
• MXML ~ Actionscript
• Familiar syntax
– Similar to C++, Java, C#, JavaScript
• Dynamic Language, Strong/Weak Typing
– Variables can hold any type
– Can bind variable to specific data type
• Visibility Modifiers
– Public - Accessible to anyone
– Private - Only accessible inside the class (current .mxml or .as)
– Protected - Accessible inside the class and subclasses
– Internal - Only accessible to classes in the same package
• Default value (when visibility is omitted)
