This is an Air native extension for managing the background music on iOS and Android. It will disable music from other apps and set the appropriate audio session for your app. It has been developed by FreshPlanet and is used in the game SongPop.
The ANE binary (AirBackgroundMusic.ane) is located in the bin folder. You should add it to your application project's Build Path and make sure to package it with your app (more information here).
You just need to call AirBackgroundMusic.getInstance().initialize().
Should you need to edit the extension source code and/or recompile it, you will find an ant build script (build.xml) in the build folder:
cd /path/to/the/ane/build
mv example.build.config build.config
#edit the build.config file to provide your machine-specific paths
ant
This ANE has been written by Thibaut Crenn (iOS) and Daniel Rodriguez (Android). It belongs to FreshPlanet Inc. and is distributed under the Apache Licence, version 2.0.
