小编Asi*_*ono的帖子

上个下午我创建了一个项目,并开始部署移动后端.我编辑了客户端代码并成功完成了一些数据插入.

在一段时间(小时)之后,我再次更改了cliend代码并且插入失败并显示错误:

com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found

由于我没有对代码进行任何实质性更改,因此我得出结论,错误发生在应用程序引擎端,因此我重新部署了项目并解决了问题.插入又来了.

今天早上我回来了404错误.这次重新部署不起作用.

我在应用引擎中得到的错误日志是:

我正在尝试在我的Android应用程序中使用Mobile Backend Starter.为此,我需要在数据存储区中存储一些数据.我正在使用提供的对象,CloudEntity但我只能一致地插入和读取String.

这是我用来发送数据的示例代码:

CloudEntity entity = new CloudEntity(TEST_KIND_NAME);

entity.put(KEY_DATE, new Date(System.currentTimeMillis()));
entity.put(KEY_CALENDAR, Calendar.getInstance());
entity.put(KEY_LONG,  Long.valueOf(Long.MAX_VALUE));                
entity.put(KEY_INTEGER, Integer.valueOf(Integer.MAX_VALUE));
getCloudBackend().insert(entity, simpleHandler);

这是我读回数据(下一个代码放在了onComplete在CloudBackendHandler:

StringBuffer strBuff = new StringBuffer();
strBuff.append("Inserted: \n");
strBuff.append("\tId = " + result.getId() + "\n");
Object o;
o = result.get(KEY_DATE);            
strBuff.append("\tDate was retrieved as : " + ((o == null)? "null" : o.getClass().getName()) + "\n");

o = result.get(KEY_CALENDAR);
strBuff.append("\tCalendar was retrieved as : " + ((o == null)? "null" : o.getClass().getName()) + …
