What is Adobe AIR?
AIR stands for Adobe Integrated Runtime which enables developers to package the same code into native apps for iPhone, iPad, Kindle Fire, Nook Tablet and other devices supported by Android.
Developers can create a common codebase to deliver and package optimized games, content and apps, enabling them to reach millions of personal computers and mobile devices.
AIR 3.7 Features
The beta release provides access to the AIR 3.7 runtime and SDK for Windows, Mac OS, iOS and Android. The key features include:
• Captive Runtime Debugging Capability for Mobile Apps – allowing Android developers to create and debug captive apps.
• Preventing backup of Shared Objects (iOS) – only user data can be backed up on iCloud. Any files that can be downloaded or generated should not be backed up and should be marked as "DoNotBackup". This attribute allows developers to control which files should be backed up or excluded.
• Forcing CPU Rendermode on some devices (iOS) – allowing control over rendermode on different iOS devices. This feature allows developers to turn on CPU rendering for specific iOS devices and utilize GPU rendering for others.
• Loading External SWFs – iOS – This feature allows the developer to externally host SWFs and load when needed. The benefits include faster initialization time, smaller apps and more control over the game app.
