我有点问题。
我有一个正在运行的 android 应用程序，非常棒。我使用“cleanservice”将操作存储在 BlockingQueue 中，然后每分钟执行一次服务运行。现在，当用户想要关闭应用程序时，就会出现问题。当他想关闭时，我最后一次运行该服务以通过 Internet 发送所有操作。
但是当没有可用的互联网连接时，我所有排队的操作都会丢失。
如果无法发送，我需要一种方法来在关闭时存储这些操作（例如在 sharedpreferences 或文件中或......）。当我再次打开应用程序时，我可以检查是否有未执行的操作需要发送。
我发现有几种存储数据的方法。但是最好的方法是什么？
if(!finaltry)
processActionQueues(true, true);
else{
// We get here when we are logging off (shutting down) and our final try has failed to send the updates to the server
// We are going to save the actions so we can send them when we log on again
}
我的操作来自这个界面：
public interface IWebServiceAction {
/**
* Executes the action on the server.
* Here you would typically do an http request to the webservice
* @param ctx
* @return
* @throws IOException
* @throws AuthenticationException
*/
boolean execute(Context ctx) throws IOException, AuthenticationException;
/**
* Indicates whether this is an urgent action. If the action is
* to be executed by the CleanService then it will execute it
* immediately if the action is urgent.
* Default = false
* @return
*/
boolean isUrgent();
/**
* If the user needs to be logged into the system before we can
* execute the action then isPrivate is true.
* Public actions that can be executed regardless of login are for
* example the login action itself, or a check for updates.
* Default = true
* @return
*/
boolean isPrivate();
/**
* Indicates whether this action requires that all previous actions are
* executed before we begin executing this one
* @return
*/
boolean requiresQueueuToBeCompleted();
}
