X分钟后自动注销，安卓 [英] Auto logout after X minutes, Android

问题描述

我期待实现一个功能，注销闲置X分钟后的用户。在经历上这么相似的答案，建议的方法似乎是 -

• 在后台运行的计时器。它安排x分钟后超时。
• 在每一个地方的用户提供应用程序（基本上所有的事件处理程序）进行交互的功能，称之为复位定时器的方法。

我想不出有什么比这更好的自己，但它似乎是一个巨大的痛苦，即使是中等大小的应用程序具有6-7不同的屏幕和一大堆的UI组件。有没有更好的方式来处理呢？

谢谢，

没有，是的。使用一个计时器，如果你实现它在 服务 或在 IntentService 。否则，不。

  

在每一个地方的用户提供应用程序（基本上所有的事件处理程序）进行交互的功能，称之为复位定时器的方法。

这解决办法是很难维持的。

您应该有一个 IntentService （展示品的>）中，可以很容易实现的 的TimerTask 或的 处理程序 ，使里面的可运行code类火灾广播到你的活动。在你的活动，你可以轻松地添加一个 BroadcastReciever 并可以注销用户如果时间超出这种情况下。当你的应用程序是不可见的用户，你就可以开始你的服务。

I'm looking to implement a feature that logs out the user after X minutes of inactivity. After going through a similar answer on SO, the suggested method seems to be to -

• Have a timer running in the background. Schedule it to timeout after x minutes.
• In every function where the user interacts with the app (basically all event handlers), call a method that resets the timer.

I can't think of anything better than this myself, but it's seems to be a huge pain even for a medium sized application that has 6-7 different screens and a whole bunch of UI components. Is there a better way to handle this?

Thanks,
Teja.

解决方案

Have a timer running in the background. Schedule it to timeout after x minutes.

No and yes. Use a timer if you're implementing it in a Service or in an IntentService. Otherwise, don't.

In every function where the user interacts with the app (basically all event handlers), call a method that resets the timer.

That solution would be hard to maintain.

You should have an IntentService (demonstrating article here) running in the background that can easily implement a TimerTask or a Handler and make the runnable code inside it fire a broadcast to your activities. In your activities you can easily add a BroadcastReciever and in that case you can log out the user if time is out. You can start your service when your application isn't visible to the user.
