I want to pull some data from a server every x minutes. IF the info contains certain information I would like to create a notification. I want this polling to happen even when the app is in the background, or the phone is asleep. I have a few questions about polling in android.

• 什么是去这样做的最好方法是什么？我应该使用

• What is the best way to go about doing it? Should I use an
  IntentService, an AlarmManager, something else?

我应该多久是轮询的数据？我想保持它 相对频繁，说每隔10分钟下。

How often should I be polling the data? I would like to keep it relatively often, say under every 10 minutes.

推荐答案

我赞成一个 AlarmManager ，我尽量不连续运行正在运行的服务，除非我真的需要，但它真的取决于你将如何使用它。

I would favour an AlarmManager as I try not to run continuously running services unless I really need to but it does really depend on how you will be using it.

如果是我的话我会（基于有限的描述）： -

If it were me I would (based on the limited description) :-

1. 设置了一个 AlarmManager 火在说10分钟。
2. 在响应报警，启动一个服务，调查的数据。
3. 在投票后，它应该为自己设定了一个新的报警再过10分钟后再次触发。
4. 在该服务自动关闭。

1. Set up an AlarmManager to fire in say 10 minutes.
2. In response to the alarm, start a service that polls the data.
3. After polling it should set itself up with a new Alarm to fire again in another 10 minutes.
4. The service shuts itself down.
