Adobe AIR SharedObject - Android / iOS - 未找到更新

标签: android ios actionscript-3 flash air

正如标题所述,我在iOS和Android上的用户报告当我将更新推送到受尊敬的店面时,他们的保存数据已被删除。游戏在应用程序加载和退出时正确保存和恢复数据。我没有更改任何保存信息位置或包名称...只是错误修复,构建,推送。

任何澄清都会有所帮助,或者我应该采取建议的冗余数据备份方案,以确保最终用户体验从此不会受到负面影响。我还想更好地了解我如何测试它,因为不允许发布包更新市场安装的应用程序。

var so:SharedObject = SharedObject.getLocal("storage"); 
var u:User;
if(so.data != null){
    u = so.data.user;
}

trace("Loading application...");

if(u != null){
    trace("LOADING SAVE DATA");
    user = u;
}else{
    trace("NO SAVE DATA EXISTS");
    user = new User();
}

我已经发现了这个问题的原因,似乎Adobe已经确定并修复了这个问题(从AIR 3.5开始)。 https://bugbase.adobe.com/index.cfm?event=bug&id=3347676

SharedObjects存储在根据应用程序使用的SWF命名的目录中,因此如果您的应用程序运行“myApp.swf”,则SharedObject将存储在“myApp”目录中。如果更改此SWF的名称(即AIR项目的相应XML构建表配置文件),则任何后续构建都会将其SharedObject存储在新位置。

此错误中描述的问题专门针对iOS表示,其中应用程序未将SharedObject存储在如上所述的相应SWF位置中,而是存储在项目的XML构建表中由“filename”属性表示的单独位置。

我还发现Adobe确实宽恕在移动平台上使用SharedObject进行持久存储。

我已经为将来的版本保存冗余开发了一个简单的备份,以防将来的更新无法持久存在SharedObject。

/** the last timestamp a deep save was completed */
private var mLastSave:Number = -1;


/**

 * sub objects.
 * @warning
 * all objects must implement variables in a "public" state.
 * Private variables are not saved within the persistance manager
 */
public function save():void{
    var so:SharedObject = SharedObject.getLocal("storage");
    so.data.user = user;
    so.flush();
    saveDeep();
}


/**

 */ 
public function saveDeep():void{
    // save on first application save or after
    // every 5 minutes
    if(mLastSave == -1 || mLastSave < getTime() + 300000){
        mLastSave = getTime();

        var file:File = File.applicationStorageDirectory.resolvePath("userSave");
        var fileStream:FileStream = new FileStream(); 
        fileStream.open(file, FileMode.WRITE);
        var ba:ByteArray = new ByteArray();
        ba.writeObject(user);
        fileStream.writeBytes(ba);
        fileStream.close();
    }   
}

            var fileStream:FileStream = new FileStream();

            fileStream.close();
            try{

            }catch( e : EOFError ){
                trace("SharedObject did not exist, attempted userSave load, failed");
            }
