有什么方法可以在应用程序关闭之前执行某些操作吗？

请说明是哪个平台！！！

对于浏览器，您必须使用 JavaScript onbeforeunload 事件和 Flash externalInterface。 Here is a how to Link!

对于 android，它看起来像这样！

if(Capabilities.cpuArchitecture=="ARM") // check if Android
{
    NativeApplication.nativeApplication.addEventListener(Event.ACTIVATE, handleActivate, false, 0, true);
    NativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE, handleDeactivate, false, 0, true);
    NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, handleKeys, false, 0, true);
}

private function handleActivate(event:Event):void
{
    // load your stuff again or whatever 
    NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;
}

private function handleDeactivate(event:Event):void
{
    // Save your Stuff and do whatever!!!
    NativeApplication.nativeApplication.exit();
}

private function handleKeys(event:KeyboardEvent):void
{
    if(event.keyCode == Keyboard.BACK){
        // Save your Stuff and do whatever!!!
        NativeApplication.nativeApplication.exit();
    }
}
