Air android/mobile：相同的sharedobject爲不同的應用程序？

Question

我有兩個應用程序，一個是試用版，另一個是完整版遊戲，都是用Adobe Air製作的。雖然通過sharedobjects解決方案保存數據不成問題，但我希望爲這兩個appsm使用「one」savegame，以便用戶在升級到完整版時可以保持其進度。我嘗試了一下。但是代碼如...：

SharedObject.getLocal（「myApp」，「/」）;

...不工作。所以問題是，有沒有辦法讓兩個Air應用程序使用同一個共享對象？或者，如果不使用，至少「讀」另一個空氣應用程序的共享對象？

答案是肯定的，我實際上是通過網絡連接和6位散列用戶在新安裝的應用程序進入，以獲取做了一個遊戲傳輸系統爲iOS和Android SO來自服務器。您可以使用本地存儲在SD卡或其他本地存儲設備上的簡單文件進行此操作。

/** 
* send this user's current save data to the server 
*/ 
public function send():void{ 

    var ba:ByteArray = new ByteArray(); 

    // Main.sv.user - is the registerClassAlias object we write/read locally via SharedObject 
    ba.writeObject(Main.sv.user); 

    var name:String = Crypto.hash("Random Secrect Salt - typically user score, name, etc."); 
    // create 6 digit hash 
    var key:String = Crypto.hash(name).slice(0, 6).toUpperCase(); 

    var request:URLRequest = new URLRequest ('https://sharedobject.com/transfer/save/name/'+name+'/key/'+key); 
    var loader: URLLoader = new URLLoader(); 
    request.contentType = 'application/octet-stream'; 
    request.method = URLRequestMethod.POST; 
    request.data = ba; 

    loader.addEventListener(IOErrorEvent.IO_ERROR, function (evt:Event) { 
     trace("error - network"); 
     onSaveRestoreEvent(1); 
    }); 

    loader.addEventListener(Event.COMPLETE, function (evt:Event) { 
     addChild(new BaseDialog("Save Sent To Server", "Your data has been sent to the server. To get this data back from the server " + 
      "you will need your secret key. Please write this six digit key down:\n"+name)); 
    }); 

    loader.load(request); 
}
