關閉應用程序之前做東西的方法？

Question

在應用程序關閉之前有什麼辦法執行某些操作嗎？
例如，有人關閉應用程序，但在它發生之前，我不得不發送一些數據到服務器...

請澄清哪個plattform！

對於瀏覽器，您將不得不使用JavaScript onbeforeunload事件和Flash externalInterface。 Here is a how to Link!

對於android它看起來像這樣！

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(); 
    } 
}
