AsyncTask toString（）方法不起作用

Question

我正在尝试在AsyncTask类中的AWS-SimpleDB中创建一个域，但是每次执行它时App都会崩溃。它工作和崩溃的情况下的代码片段如下：

这有效：

   protected Void doInBackground(Param... params) {
            private static final String APP_DOMAIN = "Domain1";

            AWSCredentials credentials = new BasicAWSCredentials(Constants.ACCESS_KEY_ID, Constants.SECRET_KEY);
            this.sdbClient = new AmazonSimpleDBClient(credentials);
            CreateDomainRequest cdr = new CreateDomainRequest(APP_DOMAIN);
            this.sdbClient.createDomain(cdr);
}

但是，当我想将Date String添加到域名时，应用程序崩溃了：

    protected Void doInBackground(Param... params) {
        static Date dt = new Date();
        private static final String APP_DOMAIN = "Domain1"+dt.toString();

        AWSCredentials credentials = new BasicAWSCredentials(Constants.ACCESS_KEY_ID, Constants.SECRET_KEY);
        this.sdbClient = new AmazonSimpleDBClient(credentials);
        CreateDomainRequest cdr = new CreateDomainRequest(APP_DOMAIN);
        this.sdbClient.createDomain(cdr);
}

我在这里做错了什么？是不是AsyncTask不能传递Date对象？

我想问题是你发送“domain1Fri Feb 20 22:50:07 EET 2015”作为域名，不能有空格。
