When creating Adobe AIR applications for Android mobile devices, it is now possible to bundle the AIR runtime into the .apk file so that users do not need to download and install the AIR runtime manually. This is a similar approach to what Adobe have taken with AIR for iOS, as applications do not need the user to install AIR on the device beforehand for applications to run. The downside to this approach is that applications suffer a much larger file size and will not receive any updates to AIR unless the application itself receives an update.
Using Flash Builder 4.6, exporting applications using the captive runtime is easy. When exporting your application for distribution, click ‘Project > Export Release Build‘ .
Click next, and then make sure you have ‘Export Application with Captive Runtime’ selected and then hit finish. Flash Builder should now export an .apk file into your bin-release folder with the bundled AIR runtime.
