Problem in android app using AIR

Some problems with orientation were in later versions of AIR, you should think about using a more recent one. AIR 3.7 is out now, you could use that.

To stop the audio you will need to listen to the deactivate events, and stop the audio, or at least mute it. Then on activate you can start it again.

In order to get a deactivation event when a phone call comes in you will need to request the read_phone_state permission in the Android publishing settings.

To detect the Back button being pressed you will need to listen for the key events, something like this:

stage.addEventListener(KeyboardEvent.KEY_UP, fl_OptionsBackHandler);

private function fl_OptionsBackHandler(event:KeyboardEvent):void {

if (event.keyCode == Keyboard.BACK) {

SoundMixer.stopAll();

}
